KSP Version: 12.3.3173 (LinuxPlayer) x86_64
Detailed Explanation: I've been recently looking to switch from Windows 10 to Linux. I purchased a new SSD for my desktop, installed it, and installed Linux Mint 20.3 on it. Shortly later, I installed Kerbal Space Program and both DLC expansions. I configured my game settings and ran the game, performing a test flight of the Aeris 3A around the Space Center. In this flight, I noticed framerate was considerably lower than what I would have expected for my hardware specifications and settings. I proceeded to check framerate with the F12 debug menu, and noted framerate was indeed lower than expected for a Stock install, averaging between 60 and 70 FPS (I have a 144 Hz monitor and a limit set to 160 frames for the game).
I proceeded to do a fresh install on my Windows 10 drive, and copied the config file from the Linux install to the Windows one, to test performance with the same settings. I found it was much higher, often maxing out at or hovering around 160. I was hoping to heavily mod my install, as I've done with previous versions in the past, but having a lower framerate right off the bat may make that nonviable.
I have tried running the game with Feral Gamemode, but I did not notice much of a performance improvement.
Is the Linux version of the game just that much worse performing than the Windows counterpart, or is there something else going on that I'm not aware of? Any and all help would be greatly appreciated!
