I'm getting several graphics glitches in the Blood and Wine expansion, including the red and yellow transparent squares in the waterfall as in the included pic. I've verified and repaired the game filis and done a fresh reinstall of the latest Nvidia drivers but nothing changes.

I had a Big lag problem after the first save game. Seems go at 10 fps. Checking the data game from gog app, he recovery 7 mb of data file.
Now run were well at medium setting on laptop hp envy 15 with 850M.

I know this topic is 3 months old, but i'm curious if anyone found solution to the problem with those red transparent squares around the waterfall. Every time I see them in my game, my immersion is immediately dead ;(
