So i play gmod, a lot, and i mean i got 4300 hours. I like to build custom things, and its never been a problem to my FPS. One day i noticed that when the high prop stuff, made out of tons of things was standing still, FPS = ok. All of a sudden, it moves and immediately 15 fps......... Please help, i've ran full system scans, reinstalled the game, put settings on lowest, yet it still does it. And gmod is a low quality game, i can run games better than it. YET it does this.
