Hello, I can report the same issue here.
I just got the game, and got that issue right away, I've tried things, updated drivers and set compatibility modes, all did not help.
Specs:
Windows 10 x64
GPU: GTX 970
CPU: i5 6600
Bug Reporter:
Connection Test - NAS-219101
Reported - NAS-219263
Trying on Beta did not solve the issue.
Looking forward to a fix.
