Hi Klaus, i have weird graphic glitches. It's started withe previous version. I have stable 60fps but after a while the graphics start "stuttering" but as i see not computing problem. After a while it's going to normal then i get the stuttering again. OSX Sierra, GTX1060 6GB on 4k. It's not resolution dependent if i try on lower setting i get the same results. On the same PC the Windows version works without any problem.
