The primary goal for Rocket League response optimization is Input-to-Render Latency Reduction. By default, Unreal Engine 3 uses several “smoothing” techniques (like OneFrameThreadLag) to make the game look fluid, but these add a small delay to your controls. This configuration focuses on disabling Motion Blur, Depth of Field, and Lens Flares at the engine level, while forcing a “Minimal-Buffer” state for the GPU.
Hardware & Connection Prerequisites
- Polling Rate: Ensure your controller (DS4, DualSense, or Xbox) is “overclocked” to 1000Hz using tools like LordOfMice’s HIDUSBF for the best results with these settings.
- Monitor Refresh Rate: These tweaks are most effective when your FPS is uncapped or set to a multiple of your refresh rate (e.g., 240 FPS for a 240Hz monitor).
- Fullscreen Mode: Always use
Fullscreen(not Borderless) to allow Rocket League to take exclusive control of the display.
File Location
Rocket League stores its hardware-specific engine settings in the following path:
%USERPROFILE%\Documents\My Games\Rocket League\TAGame\Config\TASystemSettings.ini
Technical Configuration (Code Block)
Open the TASystemSettings.ini with Notepad. Use Ctrl+F to find and modify these specific lines to minimize latency:
[SystemSettings]
# The most important setting for input lag
# Set to False to remove the 1-frame delay (Requires strong CPU)
OneFrameThreadLag=False
# Post-Processing (Set to False for Max Clarity)
AllowRadialBlur=False
AllowMotionBlur=False
AllowDepthOfField=False
AllowBloom=False
AllowLightShafts=False
AllowLensFlares=False
# Rendering Efficiency
# Disables the "soft" look for sharper edges
AllowAmbientOcclusion=False
AllowStaticDecals=True
AllowDynamicDecals=False
# Framerate & Sync
# Mandatory: Disables all forms of internal VSync
UseVsync=False
AllowD3D10=True
# Improves frame pacing on modern GPUs
AllowOpenGL=False
Strategy for Ultra-Fast Response
To achieve “Pro-Level” mechanical consistency:
- The OneFrameThreadLag Trade-off: Setting
OneFrameThreadLag=Falseis the single biggest change you can make. It forces the CPU and GPU to stay perfectly in sync. While this might slightly lower your maximum FPS, it removes the “floaty” feeling of the car, making flicking and catching the ball much more intuitive. - Disabling Bloom & Motion Blur: In high-speed aerials, “Bloom” causes the ball to “glow” against the arena lights, making it harder to see the exact point of contact. Disabling these via the
.iniensures the ball’s silhouette is razor-sharp. - Uncapped FPS Logic: In Rocket League, higher FPS reduces input lag even if your monitor can’t display those frames. Aim for 240 FPS or 360 FPS regardless of your monitor’s Hz to keep the input sampling rate as high as possible.
Key Performance Parameters
| Parameter | Recommended Value | Impact |
| OneFrameThreadLag | False | Removes the built-in 1-frame input delay. |
| UseVsync | False | Eliminates the massive 30ms+ lag caused by syncing. |
| AllowMotionBlur | False | Improves visual tracking during fast rotations. |
| AllowDepthOfField | False | Keeps distant cars and the ball in focus at all times. |
Frequently Asked Questions (FAQ)
Why does my game feel “stuttery” after setting OneFrameThreadLag to False?
This happens if your CPU cannot keep up with your GPU. If the stuttering is too much, change it back to True, but most modern gaming CPUs (Ryzen 3600 / Intel 10th Gen and above) should handle False without issues.
Should I use “NVIDIA Reflex” in-game with these settings?
Yes. Enabling NVIDIA Reflex (On + Boost) works perfectly with these .ini tweaks to further reduce the render queue and keep your GPU clock speeds at their peak.
Does lowering “World Detail” help with input lag?
Yes. Lowering world detail reduces the number of draw calls the CPU has to process. This gives the CPU more “room” to process your controller inputs and physics calculations.
Will I get banned for editing .ini files?
No. Psyonix allows the modification of TASystemSettings.ini as it only affects graphical rendering and does not provide an unfair mechanical advantage (like auto-aim or speed hacks).
Conclusion and Expected Results
By manually refining your TASystemSettings.ini to prioritize direct frame delivery and stripping away heavy post-processing, you are optimizing Rocket League for raw performance. You can expect a “heavier” but more precise car feel, instantaneous aerial response, and the removal of visual clutter during high-speed play.
