[QUOTE="edterbak, post: 621768, member: 69192"] I did some research. Owlsroost, you are right in some things. I notice a activity of the hd3450 of ~45-55% in windowed mode and once the window size is bigger it goes up to 70%. But I dont think (feeling) that this is the root of the problem. I just found out that in 32bits color settings (with aero on) I see CPU spikes. Rond the time the stutterinterval starts. With 16bit color setting (aero off I think) these cpu spikes are gone. All is good even in full screen like this. I think aero is somehow causing the cpu spikes ... maybe vsync triggerred or something. Here are some screens with dll v4 and aero on in 3 windowed modes. Does any of this can make sense to you? [/QUOTE]
