I’ll start off by saying that I have a gtx 860m. The tearing happens under very specific circumstances, target performance set to 30fps with V-Sync ON and 1920x1080p resolution. If i set the resolution to anything lower the tearing will disappear. It also disappears if I turn V-Sync off or if i switch target performance to 60 fps, the V-Sync setting does not matter in the 2nd case and neither does the resolution. Right now, I’m kind of forced to play it in 900p since 30fps with V-Sync on is the most stable performance I can get. It feels weird with V-Sync disabled and at 60fps it sometimes dips to 50-55 fps suddenly so it’s pretty annoying.
I get the same thing on my Alienware 17 R3 (GTX 980m) …Very annoying, I really hope this is worked out before release.
