I have a pretty good rig, 1TB HDD, Core i7 870, HD RADEON 4350 1 GB, 4 GB KINGSTON RAM. So how come I have lag in games, it's not so much lag but not smooth gameplay, i.e. I'll be in one place and then will appear a few meters forward a second later, it's like it skips a few frames, this has been getting on my nerves and is ruining a few games. I have tried everytrhing on low specs, have good antivirus but still can't think of anything. Please help me, Fallout 3 is unbearable like this :P
