Need for Speed Heat
Tinker Steps:Set launch options
__NV_PRIME_RENDER_OFFLOAD=1 __GLX_VENDOR_LIBRARY_NAME=nvidia mangohud %command%
Performance:Significant Performance Problems
After installing the app, I launched the game but encountered severe low FPS and stuttering. This issue was caused by a kernel setting called split_lock_mitigate
, which can be disabled by running the command:
sudo sysctl kernel.split_lock_mitigate=0
For a more permanent solution, you can modify your kernel parameters to disable it entirely. Once I applied this fix, the game ran smoothly in single-player mode. I haven't tested multiplayer yet.
In summary, both the launch issue and severe stuttering on newer kernels can be resolved with a simple kernel tweak, allowing the game to run smoothly.
