With 436.30 nvidia drivers, the vsync doesn't work. I was testing to turn vsync on from game display menu, and no results. After form nivida control panel neither. Finally I tried to lock frames with nvidia profile inspector, and nothing. Sector 3 please take a look thank you
Maybe some Problems with the latest Driver(436....). Look at the Nvidia forum. But its allready on the buglist.
Finally found my issue, if you have a GSYNC compatible card and choose GSYNC as the Sync method it wont work after 5 or 6 driver in the past..today i tried FIxed refresh rate and all ok maxed out at 100FPS.... so basically GSYNC got borked on RRRE for some mysterious reason...
