Gaf, I'm having some issues and so far asking on reddit has just been hostile.
I've started to have issues with Witcher 3 in 4k only recently. I've been playing it the last few weeks in 1080p 60fps through my TV but decided to return it to my 4k monitor today and cap it to 30 fps.
Whenever I move around be it with Geralt on the my horse the screen seems to tear and jump and cause a strange rubber band like effect. It's EXTREMELY off putting and only started happening recently (maybe since the patch?). I've played in 4k before with no issues like this so I'm not sure what the problem is.
I've recorded a video showcasing this, sorry about the phone camera but I'd like to think it can still be seen in it.
As a note, I'm running two R9 290s in CROSSFIRE but as I said before,
I haven't had issues before.

One clear part is on the 48th second where the bottom half tears/jumps
