If CarX Street lags or stutters even on good hardware, start by updating your graphics drivers (NVIDIA/AMD/Intel) and the game, because outdated drivers often cause performance issues.
Also set the game’s graphics settings to match your hardware — lowering shadows, crowd density, and post-processing can significantly smooth performance.
On PC, use V-Sync off, frame rate caps, and make sure the game is using your dedicated GPU in your system settings (not integrated graphics).
On consoles or mobile, close background apps to free up RAM/CPU resources.
Disabling overlays (Steam/Discord) and background recording can also reduce stutters.
If lag persists, check for thermal throttling (overheating) and improve cooling, and report your issue with logs to CarX support so they can optimize future patches.
