hardfork frustrations

i must be missing something here

i switched to the windows pc, installed linux on a separate drive , it has an amd something something and a gtx 970 and for some reason it feels like it renders at the same speed as that celeron/€20nvidia .... ??!?

well its 1920x1080 @ 25fps with all aliasing and set to 100% io 90 but i was expecting some serious performance increase ... probably some setting i missed after re-install
