I started GSCE today and it suddenly was running at 15 fps. At tuesday it was working just fine. In the meanwhile I had not done any system or hardware changes. Removed the whole game folder and downloaded it again from Steam. Unplugged all controllers. Deleted any nvidia profiles. Uninstalled any unnecessary programs. It was running the same way, without any mods and brand new driver profile: 16 fps. Reduced every detail to minimum: 18 fps. Tried running windowed, disabling steam overlay, disabling mirrors and gui elements, changing d3d9.ini with a sweetfx one, reinstalling directx 9 from the support directory, no result. MSI afterburner showed gpu usage of 10 percent, cpu usage of 18 percent... Went back to the other install and noticed that it was running in low fps only when I was in car... replays and menus tho were running as smooth as before, even quick replays, no matter if form cockpit or outside cameras. When I tried to drive tho, even from swingman view: 18 fps again. Every other game works as good as before. I got no idea what the problem is and what I'm supposed to do... reinstalling windows is not something I want to do right now. I could't find out how to disable the track map, I guess this could help... System: GTX 550ti 1gb, Windows 10, pentium core2quad q8200 cpu, 4 cores, 2,33 ghz, 4 gb ddr2 ram at 800mhz.
