Use DirectX 11 for the best stability and performance on modern hardware.

Located in Advanced Graphics , setting this below 1x (e.g., 0.750 or 0.834 ) renders the game at a lower resolution and upscales it, providing a major FPS boost at the cost of some sharpness.

Set this to Normal or High . Setting grass to Ultra can cost you roughly 10-15 FPS in rural areas.

Set to High . Setting this to Ultra can drain up to 20 FPS, while High offers a good visual baseline for a much lower cost.

Turn MSAA Off . This is one of the most demanding settings in the game. Use FXAA On instead for a low-cost solution that smooths edges without a major performance hit.

Reduce these sliders to 50% or lower . This significantly lowers the CPU load by reducing the number of cars and NPCs rendered at once.
