Ok so my computer has 16gb of ram an intel 4790 (not k) processor and 2 tb or storage and intel 4600 hd graphics and lately garry's mod isn't running well. I can play counter strike global fine and i've even tried playing gmod at 800x600 and I get like 20 fps and before this had happened I got like 100 fps on all servers 1024x768. It is weird and I'm not sure why this is happening I've had this going on for a few weeks and I've lowered my settings put all settings on lowest of low 800x600 and still like 30fps at best. Please help
