I have a PC with a fairly budget low-end CPU (AMD Athlon X4 845) and 8GB of RAM, for me, this results in a very slow UI, particularily in the parts selector, but I found out I can make it run much quicker for me by setting the "BeamNG.drive.x64.ui.exe" process priority to "Real-Time" (there's sometimes an extra copy that I also set to Realtime priority that helps, usually when part selector is open) Would it be possible as a minor update to make that an option within the BeamNG settings for those people like me with a lower-end PC? As mentioned, it greatly increased my performance with the UI, with virtually no in-game performance hit.
If Realtime does end up causing stability issues, how about High priority? Or is it the same case here?
