For a cautious first pass, update The Mound: Omen of Cthulhu, start with the Medium preset instead of Ultra, reduce lighting and shadows when the GPU is struggling, and enable DLSS if your graphics card exposes it. A frame cap can make delivery more consistent, especially while streaming. These steps are practical starting points, not a promise of 30, 60, or 120 frames per second: the available published material does not contain a controlled, game-wide benchmark or a complete official PC requirements table.
The game is an ACE Team first-person horror title with online co-op for up to four players. NACON lists PC, PlayStation 5, and Xbox Series X|S as platforms in its 2025 press release. On PC, patch level matters because several updates changed performance behavior.
What should you change first for better performance?
Change the game in this order: update it, use Medium as a baseline, adjust lighting and shadows, then try DLSS and a sensible frame cap. Make one change at a time and replay the same area so you can separate a real improvement from a scene that simply has less work to render.
- Install the newest build available to you. The documented patch trail includes PC performance-profile improvements, a fix for low performance after relaunching in Ultra, and geometry streaming intended to improve memory management and performance.
- Choose Medium. It is a safer troubleshooting starting point than Ultra. Medium is not a universal best setting; different graphics cards, resolutions, and scenes can change the result.
- Lower lighting and shadow quality. These are reasonable early levers when the GPU has little headroom, while preserving more of the overall image than immediately dropping every option to Low.
- Enable DLSS when available. DLSS Super Resolution can render internally at a lower resolution and upscale the image, trading some image detail for GPU headroom. The published material does not establish a fixed percentage improvement.
- Set a frame cap appropriate to your display. Treat the cap as a stability tool to evaluate, not as a required target. A community streaming report used 60 FPS, but that figure is not a universal requirement for the game.
Why should you patch the game before judging performance?
Patch history makes an old installation an unreliable basis for graphics decisions. The first post-launch update reported improved PC performance profiles and broader optimization work, while noting that more optimization was planned. Patch 1.02 specifically listed a fix for players who saw low performance in Ultra after relaunching the game. Patch 1.03 added geometry streaming for better memory management and further optimization.

The available source trail is versioned through 1.03, but it does not establish that 1.03 is the newest release on October 30, 2026. Check the build number shown by your launcher and the current official patch information before assuming your installation matches those notes. Updating cannot guarantee a particular frame rate, but it removes known software variables before you tune image quality.
What the documented patches change
| Update | Reported performance-related change | Why it matters when troubleshooting |
|---|---|---|
| First post-launch patch | Improved PC performance profiles and broader optimization work | An unpatched build may behave differently from a current build |
| 1.02 | Fix for low performance in Ultra after relaunching | Ultra is a poor diagnostic baseline until the installed build is confirmed |
| 1.03 | Geometry streaming for memory management and additional optimization | Streaming and memory behavior may improve after updating |
Which graphics preset should you use?
Use Medium first, then move individual options up or down. Ultra can look better but is not the right default for diagnosing a relaunch-related performance problem, and Low is best reserved for a machine that still cannot maintain acceptable smoothness after targeted changes.
| Setting approach | Image quality | GPU headroom | Best use |
|---|---|---|---|
| Ultra | Highest preset quality | Least headroom | Only after the current build is confirmed stable and lower presets leave clear capacity |
| Medium | Balanced preset quality | More headroom than Ultra | Recommended troubleshooting baseline |
| Low | Reduced detail and effects | Most headroom among the listed presets | When Medium still stutters or leaves insufficient GPU capacity |
| Medium plus targeted reductions | Keeps most preset quality while reducing expensive categories | Improves headroom where it is needed | When lighting or shadows are the main limiter |
The table describes a tuning order, not a benchmark ranking. A faster graphics card at 1440p may have a different limit from a modest card at 1080p, and a busy co-op scene can behave differently from a quiet corridor.
How do you tune lighting and shadows without making the game look flat?
Reduce lighting and shadow quality before abandoning the entire Medium preset. A player report about streaming tested Low and Medium settings and later identified the lighting-and-shadow category as a meaningful lever. That is anecdotal evidence, not a controlled comparison, but it gives a sensible order for troubleshooting.

- Leave the preset at Medium and record how the same scene feels.
- Lower lighting quality one step, then replay the scene.
- If stutter or low GPU headroom remains, lower shadow quality one step.
- Keep the change that improves consistency without introducing distracting loss of detail.
- Only then consider dropping the complete preset to Low or reducing other quality options exposed by your build.
Do not change several categories simultaneously if you are trying to identify the cause. Notes about smoothness, visible image changes, and whether the problem appears only in particular rooms are more useful than an unexplained switch from Ultra to Low.
Does The Mound: Omen of Cthulhu support DLSS?
A repost of NVIDIA vendor-news wording states that the game launched with DLSS Super Resolution, Multi Frame Generation, and NVIDIA Reflex support. The same report says GeForce RTX users could access newer DLSS features through the NVIDIA app. Availability still depends on the graphics card, driver, game build, and the options exposed in your installation.
How to use DLSS as a troubleshooting step
- Open the game’s graphics or display menu and look for the DLSS or upscaling option.
- Enable DLSS Super Resolution at the quality mode that keeps text and fine geometry acceptable.
- Replay the same demanding area and compare smoothness and image clarity with native rendering.
- If your hardware exposes Multi Frame Generation, treat it as a separate experiment rather than assuming it fixes a low base frame rate.
- Use NVIDIA Reflex if it is available and you are trying to reduce input latency; it does not replace the need to solve severe stutter or an overloaded GPU.
DLSS is an optional fallback, not a reason to purchase a particular GPU. The available material does not name a minimum RTX model, provide repeatable frame-rate deltas, or show that every RTX configuration benefits equally.

What frame cap should you try?
Choose a cap your system can sustain in the most demanding area you regularly play, rather than chasing a number from someone else’s setup. A cap below an unstable peak can reduce swings in GPU load and leave room for background tasks, co-op scenes, or a broadcast encoder.

The cited community streaming report used a 60 FPS test, but that is a user-specific setup and not a universal target for this game. If your display is 60 Hz, 60 FPS may be a practical experiment; higher-refresh displays may benefit from a different cap if the PC can hold it consistently. If the game still hitches at the cap, investigate frame-time spikes and streaming overhead instead of raising the limit.
How can you diagnose stuttering on PC?
Stutter can come from an outdated build, a GPU that is out of headroom, memory or geometry streaming, or the extra work created by capture and encoding. Use a repeatable sequence so each observation points to one cause.
When the GPU is near its limit
- Keep Medium and lower lighting, then shadows.
- Try DLSS if the option is available.
- Use a frame cap that the demanding scene can sustain.
This preserves more image quality than immediately selecting Low everywhere.

When hitching continues after lowering settings
Verify that the game is updated and test a less demanding scene. If geometry or memory streaming is involved, the 1.03-era optimization changes may matter, but the patch notes do not promise identical behavior on every PC. Avoid unsupported config-file edits or “optimizer” utilities; no evidence here establishes a safe tweak of that kind.
Independent reader supportYour contribution helps us test, update, and keep practical guides available for everyone.What settings are sensible when streaming with OBS?
Streaming adds a second workload. A game that feels smooth locally can still produce missed renders or an unstable broadcast when OBS captures the game and the encoder competes for GPU time.
One player report tested 60 FPS at 2560×1440 with DLSS, Low and Medium presets, fullscreen and windowed modes, Game Capture, NVENC H.264, and Twitch Enhanced Broadcasting. That report said lowering the game’s settings and disabling Enhanced Broadcasting improved OBS performance. It is a community anecdote, not a controlled benchmark, so use it as a troubleshooting branch rather than a universal recipe.
Recommended Free Tools
- Start with the game at Medium and a frame cap that leaves GPU headroom.
- Use Game Capture and check whether OBS reports missed rendering or encoding frames.
- If OBS struggles, lower lighting and shadows, then retest before dropping every option to Low.
- Compare fullscreen and windowed modes only one at a time.
- If Enhanced Broadcasting is enabled, test with it disabled; the cited report found that change helpful on its system.
- Keep the configuration that produces stable game frame times and clean OBS output, even if it is not the sharpest local image.
Do not present the report’s frame-rate or OBS counters as representative numbers for other PCs. Encoder type, resolution, capture mode, scene complexity, and graphics hardware all affect the result.

Do you need an NVIDIA GeForce RTX card?
No. RTX hardware is relevant only if you want to use the reported DLSS features. The available evidence does not provide a minimum GPU, a recommended model, or a guaranteed FPS gain, so buying an RTX card should not be the first response to low performance.
First update the game, establish a Medium baseline, reduce lighting and shadows, and test a frame cap. Consider a hardware upgrade only after those changes and your normal resolution have been assessed against the performance you actually need.
Which performance claims can you trust?
Trust the patch notes for the fixes they explicitly describe, and treat player reports as observations from one setup. The documented material does not include a publisher-backed repeatable benchmark, a complete official PC requirements table, or a universal graphics-settings matrix.
- There is no supported promise here of 30, 60, or 120 FPS on a particular class of PC.
- There is no evidence for a minimum RTX model or a fixed DLSS percentage uplift.
- There are no evidence-backed config-file edits, driver requirements, or mod instructions to add to this guide.
- “Best” depends on resolution, display refresh, co-op scene load, and whether OBS is using the same GPU.
Frequently Asked Questions
Can I run The Mound: Omen of Cthulhu at 120 FPS?
The available published material does not establish a universal 120 FPS target or a hardware combination that guarantees it. Your achievable rate depends on resolution, scene complexity, preset, and whether streaming is active, so judge it with a repeatable scene on your own build.
Is DLSS available on AMD or Intel graphics cards?
DLSS is NVIDIA’s upscaling technology and the cited launch report discusses GeForce RTX support. The supplied evidence does not document an AMD- or Intel-specific equivalent for this game, so do not assume another upscaler is present without checking your graphics menu.
Why does performance change between solo play and co-op?
The game supports online co-op for up to four players, and busier scenes can add rendering and streaming work. A setting that is stable in a quiet solo area may need a lower lighting or shadow level, or a tighter frame cap, during a full co-op session.
Should I lower resolution before changing quality settings?
Resolution reduction can provide additional GPU headroom, but the supplied game-specific material does not rank it against each individual quality option. Try the targeted lighting, shadow, DLSS, and frame-cap steps first so you can preserve clarity where possible, then evaluate resolution as a separate change.
