Here we can see spikes in regular intervals, they are very small but have no idea what can be a cause. Is not linear.
I try windows power option max performace, vsync on/off, limit framerate to 60 but same issue. Look at the graphs, do you think it's normal? Would be great if some of you perform this test as well.
Thanks for help.
