kay so recently, It should not be lagging on garry's mod. Video Card: NVIDIA GTX 650 Ti Processer: Intel(R) Cote (TM) i7-3770 CPU @3.40GHz 3.90GHz RAM: 8 GBs But Recently since the recent update my game has been randomly crashing and just exiting and going straight to my computer desktop. The FPS has been pure aids running at 30-90 and lagging horribly. But any other game like Counter Strike Global offensvie I easily run it at 200-250 FPS What I have done: Verified CSS and Garry's Mod Cache Reinstalled Garry's Mod Uninstalled all addons Updated Drivers.
Sounds like incompatible drivers on your graphics card. Recommend rolling those back. Also reinstall css if that doesn't work. Otherwise i have no idea.
I have every Counter Strike Installed, Running a Virus Scan at the moment. How exactly would I roll back my graphics card drivers.
