The primary goal for Fall Guys physics optimization is Input-to-Server Alignment. Unity-based games often suffer from “frame-rounding” errors if the frame rate is uncapped or fluctuates wildly. This configuration focuses on locking your FrameRateLimit to a stable integer and disabling Dynamic Resolution, which can cause physics “hiccups” when the GPU load spikes during a 60-player round.
File Location
The configuration file is located in your Local AppData. Ensure the game and the Epic Games Launcher are closed before editing:
%LocalAppData%\FallGuys_client\Saved\Config\WindowsClient\GameUserSettings.ini
Technical Configuration (The 2026 “Sync-Master” Template)
Open the file with Notepad++. Search for these specific variables to stabilize the physics engine:

sg.ShadingQuality=1Parameter Breakdown:
- FrameRateLimit=144.0: In Fall Guys, having 300+ FPS can actually be detrimental to physics consistency. It is highly recommended to lock this to your monitor’s refresh rate (e.g.,
144.0,165.0, or240.0). A stable, locked frame rate ensures the physics “steps” are calculated evenly. - FullscreenMode=0: Forces Exclusive Fullscreen. Windowed or Borderless modes introduce “Desktop Window Manager” (DWM) lag, which creates a delay between your button press and your bean’s jump.
- sg.ShadowQuality=0: Shadows in Fall Guys are surprisingly CPU-intensive. Since physics is also handled by the CPU, lowering shadows frees up “cycles” to ensure your movement data is sent to the server as fast as possible.
- bUseDynamicResolution=False: Prevents the game from changing resolution mid-round. Any sudden change in resolution can cause a “micro-stutter” that might eat your jump input on a disappearing tile.
Strategy for 2026 Physics Advantage
To ensure you never “slide” off a platform you clearly landed on:
- The “Polling Rate” Rule: In 2026, high-end mice/controllers support 8000Hz polling. For Fall Guys, it is recommended to drop this to 1000Hz. The game’s engine can struggle with ultra-high polling, leading to “heavy” feeling movement or jerky camera physics.
- NVIDIA Reflex “On”: If you have an NVIDIA card, ensure this is set to On in-game. It reduces the “Render Queue” to nearly zero, which is vital for the split-second timing required in Kraken Slam.
- Ethernet vs. Wi-Fi: Physics desync is almost always worsened by “Jitter” (Ping instability). In 2026, Fall Guys uses a “rollback” physics system; if your Wi-Fi drops a packet, the server will “snap” you back to your old position, usually resulting in a fall.
- Disable “Bloom” and “Depth of Field”: These post-processing effects can make distant platforms look blurry. Disabling them in the
.ini(or settingPostProcessQuality=0) makes the edges of obstacles much sharper, improving your spatial awareness.
Key Performance Parameters
| Parameter | Recommended Value | Impact |
| V-Sync | Off | Removes the 30-50ms of input delay. |
| FPS Lock | Monitor Hz | Stabilizes Unity physics calculations. |
| Anti-Aliasing | Off (0) | Sharpens the “hitboxes” of platforms. |
| Full Screen | Exclusive (0) | Best possible “click-to-jump” response. |
Frequently Asked Questions (FAQ)
Why does my bean “stumble” more than others?
Stumbling is often tied to your frame-time consistency. If your FPS is jumping between 100 and 140, the physics engine can get “confused” about the impact force. Locking your FPS in GameUserSettings.ini usually fixes the “random stumble” bug.
Can I use “Stretched Resolution” in Fall Guys?
Yes, you can set ResolutionSizeX=1728 and ResolutionSizeY=1080 in the .ini. While it doesn’t give a huge advantage, some players find the “wider” platforms easier to land on.
Does sg.ResolutionQuality=100 matter?
Yes. If this is below 100, the game is upscaling, which adds a tiny amount of processing lag. For physics-heavy games, you want the cleanest “one-to-one” pixel output possible.
My settings reset when I open the Epic Games Launcher!
After saving your changes, right-click GameUserSettings.ini > Properties > Check “Read-only.” This prevents the launcher from “syncing” your settings back to the cloud defaults.
Conclusion and Expected Results
By locking your FrameRateLimit to your refresh rate and forcing Exclusive Fullscreen in your GameUserSettings.ini, you are aligning your hardware’s output with the game’s physics steps. You can expect more consistent jumps on moving platforms, reduced “input lag” during grabs, and the elimination of micro-stutters during high-player rounds.
