I'd recommend just turning those few settings down. They barely do anything and 60 FPS is more worth it. Even hairworks is barely noticeable on Geralt and I meant the leaves look bad regardless of settings.I think I can accept 30-40 at 1440 with everything maxed. What cpu do you use? I have a 2600k at 4.5ghz and 980, don't know if I should buy it now or wait for future updates.
My CPU's a 3770K (currently at stock), your 2600K will be fine.
