nah, l4d2 with shit ton of mods i have 300fps & gta5 70
&also no virus, alrdy checked
40-59 you call that low Fps?
Then i must be playing in Photo mode cuz i barely get 30.
Anyways you can try doing a disc Defrag,since your PC is very old and probably your HD is a mess,but behare that is going to take one hell of time to do that.
well, was used to constant 60fps, alrdy hard to race with ´my current fps, but racing with 30 fps is hardcore
i hope kenny can help me
