Fix Tokyo Xtreme Racer Slow Motion and Low FPS Issues

If your car feels like it is moving through molasses even when your speedometer says 150, you are dealing with a known engine issue where the game physics are tied directly to your frame rate. When your FPS dips below 60, the entire simulation slows down to compensate. You can stop this by tuning the graphics and locking your frame rate.

Why this happens

The game engine couples its physics calculation with the frame rate, meaning any instability causes the game to enter slow motion. Overly aggressive settings like Global Illumination and poorly implemented Frame Generation are the primary culprits for these frame drops.

Steps

1. 01
   Navigate to Escape menu then Options and Graphics Settings to begin the manual configuration.
2. 02
   Set Global Illumination to Medium and Shadows to High to immediately recover significant frame rates.
3. 03
   Adjust Post Processing and Reflections to Medium to reduce visual clutter and stuttering.
4. 04
   Set your FPS Limit to 60 if your hardware cannot maintain a perfectly stable framerate above that, which prevents the physics-related slow motion bug.
5. 05
   Turn off V-Sync and Frame Generation entirely, as these cause conflict with the game engine, and use G-Sync or FreeSync through your GPU control panel instead.
6. 06
   Use DLSS set to Balanced with a sharpness of 0.3 if you are on an NVIDIA card, or FXAA if you are not, to stabilize rendering performance.
7. 07
   Restart your game every 10 to 15 minutes if you notice a gradual decrease in performance, which indicates an active memory leak that requires a fresh process.

Still not working?

If you are still experiencing stutters after these changes, perform a clean graphics driver installation using DDU (Display Driver Uninstaller). Ensure your game is installed on an SSD to prevent asset streaming hitches. If issues persist, check that your GPU temperature is not throttling your clock speeds during long sessions.

Frequently asked questions

Does the slow motion bug mean my save file is corrupted?

No, this is strictly a performance and engine synchronization issue. Your save data remains intact.

Why does the game run fine at first but get worse later?

The game currently suffers from a memory leak. If your FPS tanks after 15 minutes of play, it is filling your system memory; restarting the game is the only temporary fix until the developers patch it.

Should I use Frame Generation for higher FPS?

No, keep Frame Generation off. It is currently broken and often causes the very slow motion issues you are trying to avoid.
