Start with the Steam Deck’s native 1280×800 output, the maximum graphics preset, and a 60 FPS target. A September 28, 2026 report on the current Poly Fighter demo found that combination remained stable during play. If your Deck draws more power than you want during long fights, reduce shadows, effects, or post-processing one step at a time before changing resolution. Use AMD FSR only if the game actually exposes the option, and treat Proton Experimental as a compatibility fallback rather than a required setting.
Poly Fighter is a single-player roguelike fighting game in Steam Early Access. HeartLoop Games labels it Steam Deck compatible, and its Early Access announcement lists 16 playable fighters. Because the game is still being updated, keep a known-good profile and change one variable at a time when a patch alters performance.
The best starting profile
The profile below is the most defensible default for the current demo: it prioritizes the low-latency feel that matters in a fighting game while preserving the Deck’s sharp native image.
What’s actually slowing this PC down?
Pick the symptom - the matching free tool is one click away.
| Setting | Recommended starting value | Why | Evidence or qualification |
|---|---|---|---|
| Output resolution | 1280×800 | Uses the Deck’s native panel resolution and avoids unnecessary scaling. | The current demo was reported stable at this resolution. |
| Graphics preset | Maximum | Preserves visual quality without an established need to lower the preset. | The published demo report found maximum settings stable. |
| Frame-rate target | 60 FPS | Gives controls the most responsive feel among the documented options. | 60 FPS is the tested result for the current demo; no Poly Fighter-specific 40 FPS test was published. |
| Upscaling | Off initially; AMD FSR only if available | Native rendering is the clearest baseline. FSR can help when a lower internal resolution is needed. | FSR is an optional Steam Deck technique, not a confirmed requirement for this game. |
| SteamOS frame limit | 60 FPS | Provides a consistent ceiling and prevents the game from rendering beyond the target. | SteamOS exposes a per-game 10–60 FPS limit. |
| TDP limit | Leave at the default first | Establishes a performance baseline before trading power for battery life. | SteamOS provides a 3–15 W TDP slider; a lower value can reduce consumption but may reduce smoothness in demanding scenes. |
| Compatibility tool | Default Proton | Avoids changing a working installation unnecessarily. | Proton Experimental is a fallback for update-related launch or rendering problems. |
This is a starting point, not a promise that every future build will behave identically. The 60 FPS observation applies to the current demo described in the September 28, 2026 report, not to every Early Access update, every Deck model, or every scene in a later release.

Why native 1280×800 is the right first choice
The Steam Deck’s built-in display is 1280×800. Selecting that output gives you a one-to-one target for the panel instead of asking the Deck to upscale a smaller image or render a wider aspect ratio that leaves unused space. For a game with readable attack animations and timing-sensitive inputs, beginning with the panel’s native resolution also makes it easier to judge whether a later quality change is actually helping.
Do not lower resolution simply because an upscaler exists. Upscaling is useful when the GPU cannot sustain your chosen frame rate, but it introduces an additional image-processing step. Test native rendering first, then compare the same scene with FSR if you need to reduce load. Keep the output at 1280×800 while testing so that only the internal rendering method changes.
How to set the resolution
- Launch Poly Fighter and open its video or graphics settings.
- Choose 1280×800 if the game offers an explicit resolution selector.
- Use fullscreen or borderless fullscreen according to the game’s available labels; select the mode that fills the Deck display without cropping.
- Apply the change and return to a fight or training area before judging performance.
If the game does not show a resolution selector, leave the Steam Deck display at its native setting and use the game’s own default. Do not force a different resolution through SteamOS until you have confirmed that the in-game option is unavailable.
Maximum settings versus lower settings
The current demo report found maximum settings stable, so there is no evidence-based reason to begin with a reduced preset. Maximum is also a useful reference point: once you know how the game behaves at that level, every later change has a clear purpose.
When to lower the preset
Lower the preset only when you observe a problem that it can plausibly address: sustained frame-rate drops, unusually high power draw, excessive heat, or a fan level you find distracting. A lower preset is not automatically better for battery life if the game was already meeting its target efficiently. Make one change, replay the same type of encounter, and watch both the frame counter and power behavior.
Which options to reduce first
The published report says that reducing graphics settings addressed unexpectedly high power consumption without visible quality loss, but it does not identify a single most-effective option. Use a conservative order:
- Lower shadows one step. Shadow maps can be expensive while having little effect on the clarity of characters and attacks.
- Lower effects one step if the arena contains frequent particles, flashes, or impact effects.
- Lower post-processing one step if the game provides a separate control for bloom, depth of field, motion blur, or similar screen effects.
- Only then consider a broader preset change or an internal-resolution reduction.
These are practical tuning choices, not Poly Fighter-specific benchmark results. If a particular build names options differently, use the closest equivalent and record what you changed so you can restore the previous profile after an update.

Frame-rate targets: 60 FPS or a lower cap?
A 60 FPS target is the appropriate first choice for responsive fighting controls. It reduces the time between rendered frames compared with a lower cap and gives you a clear reference for judging input timing. The current demo has a published stable-60 result at native resolution and maximum settings.
A lower cap can make sense when battery life, fan noise, or heat matters more than minimum input latency. SteamOS allows a per-game frame limit from 10 to 60 FPS through the Quick Access performance controls. There is no published Poly Fighter-specific benchmark for a 40 FPS cap, so selecting 40 or another lower value is a practical experiment, not a tested recommendation.
How to set the SteamOS frame limit
- Start Poly Fighter and leave it running.
- Press the Steam Deck’s Quick Access button (the button with the three-dot icon).
- Open the Performance tab.
- Enable the frame-limit control if it is disabled, then choose a value between 10 and 60 FPS.
- Return to the game and play a repeatable section, such as several fights, before deciding whether the cap feels consistent.
Keep the in-game frame-rate setting and the SteamOS limit aligned when possible. If the game has its own limiter, use one primary limiter rather than stacking several different caps, which can make behavior harder to interpret. If frame pacing feels uneven, restore the 60 FPS SteamOS limit and test the game’s own setting separately.
Power draw, TDP, and battery-focused tuning
During prolonged fights, the current demo was reported to consume more power than expected. The same report found that lowering graphics settings could address that behavior without an obvious loss of image quality. Because the report does not isolate the responsible option, tune in small steps instead of assuming that one slider is the cause.
Monitor before changing anything
- Open the Quick Access menu while the game is running.
- Select Performance.
- Enable the performance overlay or the available readouts for frame rate and power behavior.
- Play for several minutes, including a busy fight, and note whether the frame rate remains at your target and whether power draw rises steadily.
A brief spike is different from a sustained increase. Judge a change over a comparable session rather than from a single menu screen or loading transition.
Lower graphics load before lowering TDP
If power use is high but frame delivery is already smooth, first reduce shadows, effects, or post-processing by one step. This keeps the frame-rate target intact while removing work that may not be visible during play. If the game still draws more power than you want, consider a lower frame cap, accepting that the controls may feel less immediate.
Using the TDP slider
SteamOS exposes a TDP range of 3–15 W in the Performance tab. A lower TDP can extend battery life, but it also limits the power available to the CPU and GPU. Windows Central’s Steam Deck guidance notes that more CPU-intensive or graphically demanding games require more power to run smoothly. For Poly Fighter, do not jump straight to a low value: reduce TDP gradually and verify that the frame rate and frame pacing remain acceptable in a busy fight.
Rank #3
- Operating System: SteamOS 3.0
- Open Quick Access and choose Performance.
- Enable the manual TDP control.
- Reduce the value by a small increment.
- Return to the same type of fight and watch for missed frames, stutter, or delayed visual feedback.
- Restore the previous value immediately if the target is no longer maintained.
TDP tuning is a battery trade-off, not a quality upgrade. Keep the default value as your reference profile so you can tell whether a later game update, rather than your manual limit, caused a change.
FSR: when to use it and what it changes
AMD FidelityFX Super Resolution renders the game internally at a lower resolution and upscales the result to your selected output. Windows Central recommends using FSR when a game supports it, but Poly Fighter is not documented as requiring it. Since the current demo already has a stable native-resolution report, leave FSR off for your first test unless the game exposes the option and you need additional performance headroom.
Use FSR when these conditions apply
- The game offers FSR in its own graphics menu.
- Native 1280×800 no longer holds your chosen frame target after a game update or a demanding scene.
- You are willing to trade some fine image detail for lower rendering load.
FSR setup procedure
- Open the game’s graphics or display settings.
- Enable AMD FSR only if it appears as a supported upscaling option.
- Keep the output resolution at 1280×800.
- Choose the least aggressive quality mode that solves the performance problem.
- Inspect thin lines, character outlines, and moving effects during a fight for shimmer or softness.
If the image looks worse and the frame rate is already satisfactory, turn FSR off. Do not combine an unknown in-game resolution change with FSR during the first test; changing both at once prevents you from knowing which setting caused the result.
Compatibility: default Proton first, Proton Experimental second
Poly Fighter is labeled Steam Deck compatible, so the default compatibility configuration is the sensible starting point. Proton Experimental is a general troubleshooting option, not a confirmed Poly Fighter requirement.
When to try Proton Experimental
- The game previously launched and stops launching after an update.
- A patch introduces a rendering problem that was not present before.
- The default Proton configuration produces a repeatable black screen, crash, or severe visual corruption.
How to switch compatibility tools
- Exit the game.
- Open your Steam Library and highlight Poly Fighter.
- Open Properties.
- Select Compatibility.
- Enable the option to force a specific Steam Play compatibility tool.
- Choose Proton Experimental, close Properties, and launch the game.
Test the new tool by itself before changing graphics or TDP. If it does not help, return to the previous compatibility selection. A compatibility change can affect shader compilation, launch behavior, or rendering independently of your performance settings.

Rank #4
- Valve is entering the gaming console marketplace with the new Steam Deck, a console geared towards PC gamers. The Steam Deck can be docked to a monitor, and used as a PC, or docked to a TV.
- Players can play a huge variety of games at any time with the comfort of a console and the freedom of a PC. Not anti-glare screen.
- Like the name suggests, the Steam Deck will include upgraded 1TB storage, and will include a carrying case. A micro SD slot will also enable expanded storage.
- Valve partnered with AMD to create a specialized APU optimized for handheld gaming, and Valve says the chip will deliver performance to run AAA gaming titles.
- The Steam Deck is outfitted with a 7-inch touchscreen, and two trackpads under the control sticks that allow gamers to operate games never designed outside of mouse and keyboard capabilities.
Troubleshooting by symptom
The game launches but performance falls below the target
- Confirm that the SteamOS frame limit has not been set below 60 FPS.
- Check whether the game switched away from 1280×800 after an update.
- Return to the maximum preset only after confirming that no hidden resolution change occurred.
- If the problem persists, lower shadows, effects, or post-processing one step at a time.
- Use FSR only if the game provides it and native rendering cannot maintain your chosen target.
Power use climbs during long fights
- Verify that the frame rate is not uncapped.
- Reduce one graphics option, beginning with shadows, effects, or post-processing.
- Repeat a similarly long fight and compare behavior.
- If the image remains smooth but battery use is still too high, test a lower frame cap.
- Only then experiment with a lower TDP, restoring the previous value if frame pacing deteriorates.
The image becomes soft or shows shimmering
Disable FSR and return to native output. If the issue remains, restore the previous post-processing value and check that the game is not rendering at a lower internal resolution. Change one setting per test so you can identify the source.
An update causes a black screen, crash, or rendering fault
- Restart the Deck and verify that the game update completed.
- Launch once with the default compatibility tool.
- If the fault remains, use Properties > Compatibility to force Proton Experimental.
- Test without changing resolution, frame limit, or TDP.
- If Proton Experimental does not resolve the issue, return to the prior tool and wait for a game or Proton update rather than layering multiple unverified tweaks.
A repeatable testing method
Settings are easier to evaluate when every test follows the same routine. Use the same display brightness, battery state, and type of encounter where practical. Start from the responsive baseline, then change a single variable. Play long enough to include ordinary movement and a busy fight, not just an idle menu. Record the frame-rate reading, whether controls feel consistent, and whether power behavior changes.
Do these 3 things before closing this tab:
1Scan for outdated or missing drivers - takes under a minute2Clear out junk files and repair common Windows errors3Fix the driver behind crashes, sound loss and screen glitchesDo not treat a single short session as proof that a setting is universally better. Early Access builds can alter shaders, effects, arenas, or default configuration. If a patch changes behavior, reproduce the issue with the baseline before deciding that FSR, a lower cap, or Proton Experimental is necessary.
Steam Deck controls and session planning
Because Poly Fighter is designed for single-player runs, a stable local profile is more important than a network latency configuration. Keep the frame-rate limit and graphics choices per game rather than changing global Steam Deck settings that could affect unrelated titles. Quick Access controls are especially useful when moving between a demanding fight and a menu: open the Performance tab, make the smallest adjustment needed, and return to the game.
Long sessions also make storage and charging practical concerns. Carrying additional games on a compatible microSD card or using a USB-C power bank can be convenient, but neither accessory is a performance requirement for Poly Fighter. They do not replace the frame-limit, graphics, or TDP tuning described above.
What may change as Early Access continues
The game’s Steam Deck compatibility label and the current demo’s stable native-resolution result describe the software available at the time of those statements. Early Access updates can change default graphics settings, shader behavior, effects, loading, or compatibility. After a major update, confirm the output resolution, preset, frame limit, and compatibility tool before assuming that an old profile still applies.

Keep the following recovery order: restore 1280×800, maximum settings, and the 60 FPS limit; remove manual TDP restrictions; disable FSR unless it is needed; and use the default Proton configuration. This returns you to the documented baseline before you investigate a new problem.
Final recommendation
For most Steam Deck owners, use 1280×800 at the maximum preset with a 60 FPS target and the default TDP and Proton configuration. That matches the current demo’s documented stable setup and gives the controls the responsive feel expected from a fighting game. If prolonged fights draw too much power, lower shadows, effects, or post-processing one step at a time. If battery life remains the priority, test a lower frame cap and then a modest TDP reduction, understanding that neither combination has a published Poly Fighter-specific benchmark. Reserve FSR for a game-supported situation where native rendering no longer meets your target, and keep Proton Experimental as a targeted fallback for update-related launch or rendering failures.
