I'm pretty sure I have one. It started a few weeks ago when I could ride coasters like Atlas or even Thermite with a good 80-100 FPS, but now for some reason I can hardly get NEAR that. Now I can't even ride Atlas, and Thermite runs on 8-20 FPS and even if I only build a station my average is just 10-20 FPS. I even set my specs to low!
I'm not the most computer savy person, so I was wondering if you can help me find a program that can help get rid of it for free or that's cheap and reliable or is there something I can do myself to fix it since it's affecting my mom and her work and just everyone, really.[:(]
