Yes also DX11... Graphics are mostly high. What kind of graphic settings you want to know?
A friend of me does not have that problem - never seen. He knows a lot more about computer than me and he is going to look at my system in the next weeks maybe...
I also think, that it is a "system" issue, not a server issue. I don't think this problem has always existed... but I can't say when the problem started...
If he can locate the problem i will tell you all, of course 🙂
