My fps lately has been stuck at 40 fps which I personally think isn't very good. I tried updating my graphics card and lowering quality but it still is stuck at 40 fps. Before the 40 fps, i had 128 fps average, but now its just stuck at 40 no matter what I do. I just want to know what the problem is so I can try to fix it, and some tips to get some better fps. 
SoundChaosDebug1 votesUninstall your video driver and try using this.
Also your resolution settings can make a difference, can you give us a little more information on what you have for your video settings?

SoundChaosDebug1 votesThe driver pack solutions needs to be downloaded in a torrent, because it's like 10 gigs of drivers.
It will fix up a shit ton of drivers on your computer with out even realizing you needed more drivers than you think.
I use it on computers where I put a fresh operating system on and it saves so much time.
