I'm having some kind of issue with video spikes both in the game and watching streaming video and its giving me fits. With Comcast I believe its Flash related cause I have few when I unchecked Hardware acceleration in Flash controls it doesnt happen as much but the playback quality is lower. In Aces High it can only be my connection or my video card and I dont see why it should be my card.
I have an i7 950 at 3.07 so the processor is a little old and seems to stress when gaming at 4K. I have 12 gig RAM and considering upgrading that. I tried that Project Lasso software with mixed results, it prioritzes processes running in background. Actually I think Im having fewer spikes in game with it but still enough to bother me. Things is a few months ago I was running everything flawlessly.
I'm stumped with this. It can really be anything.
