The safest way to improve FPS is to lower demanding in-game quality settings one at a time, measure the result in the same repeatable scene, and leave GPU clocks and voltage at their defaults. Use a frame cap or variable refresh rate (VRR) when your goal is steadier frame pacing or less tearing. Overclocking and undervolting are optional experiments, not required steps, and neither has a guaranteed gain for every game or graphics card.
What you are trying to improve: FPS, smoothness, or latency
These outcomes overlap, but they are not interchangeable. Rendered FPS is how many frames the GPU produces. Frame pacing is how evenly those frames arrive; uneven frame times can feel stuttery even when the average FPS looks high. Input latency is the delay between an action and the displayed result. A setting that improves one may leave another unchanged or make it worse.
For example, a frame cap can deliberately lower the peak FPS number while preventing the GPU from rendering frames your monitor cannot display. V-Sync and VRR primarily control presentation and tearing. They do not create additional rendered frames. Lowering a GPU-heavy quality option can increase rendered FPS, but the gain depends on the game, your graphics card, and whether that option is actually the bottleneck.
Establish a trustworthy baseline before changing anything
Without a repeatable baseline, it is easy to mistake a different scene, a shader-compilation hitch, or normal run-to-run variation for an improvement. Record the following before tuning:

Run the same scene for the same amount of time after each change. Change one setting at a time, keep other variables constant, and write down the result. There is no universal FPS percentage that can be promised from any particular setting.
Lower in-game settings first
Game settings are the most reversible way to trade image quality for performance. NVIDIA’s latency guidance recommends reducing game settings when performance is insufficient. AMD documentation specifically notes that limiting tessellation can improve FPS in games that use high tessellation. The size of any improvement varies by title and hardware, so use the game’s performance indicators and your own measurements rather than a fixed “best” order.
Start with settings the game identifies as expensive
Many games show estimated performance impact beside options or expose a benchmark run. Begin with an option marked high impact, reduce it by one level, and test. Common candidates include geometry or tessellation-related detail, volumetric effects, shadows, reflections, and other effects that substantially increase GPU work; which of these matters most is title-dependent. If the game does not identify an expensive option, test one setting at a time and keep the change only when the repeated scene improves.

Keep the visual trade-off explicit
Lower quality can raise FPS where the setting is a bottleneck, but it reduces detail or effects. Compare the scene while moving, not only in a static screenshot: shimmering, shadow breakup, distant-object pop-in, and reduced reflections may be more noticeable during play. If an option produces no measurable change, restore it and test another rather than lowering everything indiscriminately.

Resolution is a deliberate image-quality decision
Reducing resolution can reduce GPU workload, but the available sources do not establish a universal resolution recommendation or a stable FPS gain across games. Keep native resolution when image clarity is the priority. If you choose a lower resolution or an in-game resolution scale, record that change separately because it changes image quality as well as performance.
Use a frame cap when the display cannot show every rendered frame
A frame cap limits the maximum rendered FPS. It is useful when the game regularly renders above the display’s refresh rate or when you want to remain inside the supported range of a VRR display. AMD recommends V-Sync or a cap when FPS regularly exceeds display refresh, describing either as a way to provide a tear-free experience in that situation.
How to choose a cap
First check the monitor’s refresh rate and the game’s sustained FPS in the baseline scene. Set an in-game cap at a value your system can hold consistently and test frame pacing and input response. A cap can reduce the peak FPS number by design; that is the trade-off for avoiding unnecessary rendering and, with VRR, staying within the display’s operating range. The best value depends on the display, game, and your preference for responsiveness versus consistency.

Driver-level limiters are an alternative when a game lacks a reliable limiter, but labels and behavior can vary by driver version. Do not claim that a cap increases raw FPS; its benefit is controlled presentation and workload.

Understand V-Sync, Adaptive V-Sync, and VRR
V-Sync
V-Sync synchronizes frame output with the display refresh cycle and can reduce tearing. Conventional V-Sync behavior can stutter when the frame rate falls below the synchronization cap, as NVIDIA explains in its Adaptive V-Sync documentation. Exact behavior depends on the game and implementation, so test with the title you play rather than assuming one universal result.
Adaptive V-Sync
NVIDIA’s Adaptive V-Sync approach changes synchronization behavior as FPS changes, addressing the trade-off between tearing at high FPS and stutter when FPS drops. It is a presentation option, not a method for rendering more frames. If latency is your priority, compare it directly with an uncapped run and with VRR on your display.
FreeSync and G-SYNC
VRR matches the display’s refresh timing to the GPU’s frame rate within a supported range, which can reduce tearing and stutter when frame rate fluctuates. It requires compatible hardware and correct configuration. AMD says to enable FreeSync on the display and in the driver, and requires a FreeSync-compatible display and GPU. NVIDIA states that G-SYNC requires a G-SYNC or G-SYNC Compatible display.

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 glitchesAfter enabling VRR, verify that the monitor reports the feature as active and that the game is running on the intended display. If the game exceeds the display’s VRR range, a cap can keep it inside that range. If it drops below the range, VRR may no longer cover every frame; lowering a demanding setting can help maintain the target range.

GPU clocks and voltage: optional, gradual, and reversible
Overclocking raises operating targets; undervolting reduces voltage for a given performance target. Both can change performance, efficiency, temperature, and stability, but the available guidance does not establish a guaranteed gain or a universal stable setting. Treat them as experiments only after in-game settings and presentation controls have been checked.
Use the controls supplied for your GPU
AMD Software: Adrenalin Edition documents automatic undervolting that reduces voltage while maintaining clock speeds, with the aim of improving performance per watt. It also documents manual overclocking and a GPU stress test. Availability depends on the GPU and software support. NVIDIA and other vendors may expose different controls, so use the current documentation for your exact model and driver rather than copying a value from another card.
Change one control at a time
- Save or record the factory/default values.
- Apply one small clock or voltage change.
- Run the vendor stress test, then play the game and scene you actually care about.
- Watch for crashes, reboots, driver resets, visual artifacts, corrupted textures, or sudden clock drops.
- Revert the last change when any symptom appears, then retest at the previous stable value.
AMD documents that, in its software, a failed stress test that causes a crash or reboot resets AMD tuning settings to defaults. That reset behavior is specific to the documented AMD software; do not assume another vendor’s tool behaves the same way. Keep a written record so you know which setting to restore if a driver update or game patch changes behavior.
Setting trade-offs at a glance
| Setting or control | Primary effect | Trade-off or limitation | Use it when |
|---|---|---|---|
| Lower in-game quality | Can increase rendered FPS when the reduced option is a bottleneck | Image detail or effects decrease; gains vary by game and GPU | Your baseline shows a GPU-bound scene and the visual loss is acceptable |
| Frame cap | Limits maximum rendered FPS and can keep output within a VRR range | Peak FPS is intentionally limited | FPS regularly exceeds refresh rate or fluctuates around a VRR limit |
| V-Sync | Synchronizes output to refresh and can reduce tearing | Conventional behavior can stutter when FPS falls below the cap | Tearing is distracting and the game can sustain the display timing |
| FreeSync or G-SYNC | Matches refresh timing to GPU frame rate over a supported range | Requires compatible display, GPU, connection, and configuration | You have a compatible VRR monitor and variable FPS |
| Undervolting or overclocking | May alter efficiency or performance | No guaranteed gain; instability can cause artifacts, crashes, or resets | You are willing to test gradually after reversible settings are exhausted |
A low-risk tuning sequence
- Measure the baseline. Use one repeatable scene and record resolution, quality settings, average FPS, and frame-time or 1% low data when available.
- Identify the bottleneck. Use the game’s own performance indicators and monitoring data. Test a setting only when it appears relevant to the GPU workload.
- Reduce one demanding quality option. Tessellation is an AMD-documented example for games that use it heavily; other options must be evaluated per title.
- Repeat the same test. Keep the change only if it improves the metric you care about without an unacceptable visual loss.
- Test presentation controls. If FPS exceeds refresh, compare an in-game cap and V-Sync. If you have compatible VRR, enable it on the display and in the driver, then verify operation.
- Consider GPU tuning last. Record defaults, make one small change, stress-test, play-test, and revert immediately when instability appears.
Troubleshoot common results
FPS did not change after lowering a setting
The option may not be the bottleneck, or the game may be limited by the CPU, a frame cap, V-Sync, or another subsystem. Restore the setting and test a different GPU-heavy option. Do not keep lowering image quality without a measured benefit.

The FPS number is high but motion still stutters
Check frame-time consistency rather than average FPS alone. A cap, VRR, or a different synchronization mode may improve presentation even when the average number stays similar. Also test the same scene after shader compilation or loading has settled, because inconsistent test conditions can mimic a setting problem.
Enabling VRR changed nothing
Confirm that both the monitor and GPU support the selected technology, that the feature is enabled in the monitor menu and driver, and that the game is using that display. G-SYNC requires a G-SYNC or G-SYNC Compatible display; FreeSync requires a compatible display and GPU. A game running outside the supported refresh range may also limit the visible benefit.
A tuning change caused a crash or artifacts
Return to the last known-good clock and voltage. Remove the change rather than compensating with another control, then rerun the stress test and the game scene. On AMD Software, a crash or reboot during its documented stress test can reset tuning to defaults; verify the values before making another adjustment.
When a VRR monitor is worth considering
A variable-refresh-rate gaming monitor can make fluctuating FPS look smoother, but it does not increase the GPU’s rendered FPS by itself. Before buying one, check that your graphics card supports the monitor’s VRR technology, that the monitor’s supported refresh range covers the FPS you normally achieve, and that your connection and driver support the required mode. AMD requires a FreeSync-compatible display and GPU, while NVIDIA requires a G-SYNC or G-SYNC Compatible display for G-SYNC.
Quick Recap
Practical decision checklist
- Want more rendered FPS? Lower a demanding in-game setting and measure the same scene.
- Want less tearing? Test V-Sync or compatible VRR.
- Want steadier frame pacing? Try a cap that your system can sustain and evaluate frame-time data.
- Want lower latency? Compare synchronization modes in the game you play; do not assume a higher FPS number automatically feels faster.
- Want better efficiency or an experimental performance gain? Try vendor-supported undervolting or overclocking only after recording defaults and preparing to revert.
- Seeing crashes or artifacts? Undo the last tuning change and return to the last stable configuration.
