The lag is almost like a freeze, it just slows down horrendously.
I used HD Tune, it said everything was fine.
and, no I don't have this problem when there are no games running.
I'll try lowering the resolution in a little bit and post results.
I've seen this happen in games like shaiya ( rarely ) and Minecraft
any suggestions for a better cheap-ish graphics card? mines already probably between 1-2 years old :v.
edit: lowering the resolution seems to have solved the problem, thanks
