I'm using the latest version. The "heavy" mods are all of the USI mods https://umbraspaceindustries.github.io/UmbraSpaceIndustries/ plus some qol mods and other science experiments CPU: Intel Core i7-2600 Graphics: AM RX 570 I had no problems playing on windows, but i'm using only linux now

Already tried that, but thanks!

I've installed KSP in my, now main OS, Manjaro. With the vanilla game i had no problem, but after installing a couple mods, around 20, the frames in the VAB drop to around 3-5 per second. The problem is that in game, with a 120 plus parts the game runs absolutely smooth. Any suggestions?
