I was trying to play CS:GO and heart of the swarm today and I was getting lag on both of them. In heart of the swarm, i got a constant 30 - 40 fps the whole time, and I have a i5 @ 3.2 ghz and 8gb ddr3 ram, I should have no problems running at ultra with my specs, but couldn't even get good fps on high. On cs:go I had a constant 100 fps, dropping to 20 at random intervals, which is impossible to play the game like that.
I hear that the clocks change from 1000 to 300mhz alot for some unkown reason and I can't find a good fix for this.
If anyone could help me I would be very thankful.
