If you restart the apps does it fix it for 10 minutes again? Or is it still as bad? I'm wondering if it's a heat issue...

just to say it must definitly be something to do with heat. having the side of the case off has prevented the problem. Thing is leaving the case off means it will fill up with dust and dirt so it can only be short term fix. How do i keep my graphics card more cool?
Rearrange your cards so that there's a bit of space for the graphics card's fan to do its thing, make sure the back of the case isn't blocked so that air can get out, if the case is on carpet, raise it off it a few inches, and make sure your case isn't right next to a radiator.Later i went on lotro to see all the new ftp changes and went to help some friends and i was getting movement lag, like people running on the same spot then jumping forward and everything glitching when im walking.
I'm not sure if that would be a graphics problem. Running on the spot then suddenly catching up deffinately sounds like a network/latency issue to me. But this doesn't explain it going slowly in Windows.
Run a full AV/malware scan? You could have picked something up causing these issues?
