Tokyo Xtreme Racer is currently in Early Access on Steam. The graphics and style look rather dated but the game is very well polished and runs great on Steam Deck with some adjustments. These adjustments won't lock down the FPS counter but will give a good balance of looking good and maintaining above 40 FPS 99% of your game time.

Best Settings:

FPS Settings: 60 FPS

Graphics Quality: Medium

Shadows: Low

Global Illumination: Low

Upscaling Quality: Quality
