For those looking to buy a Geforce 5xxx series GPU, I warn you that if you play BDO with 21:9+ aspect ratios that you will encounter an intrusive visual bug. Flickering black checkers will fill the top half of your screen. The only way to sort of get rid of them is to use the ultra graphic mode or FSR with balance setting (I think). If you decide to use ultra mode you will take a significant fps hit.  Many users are experiencing this problem, I've reported it several times since the beginning of this summer. But the problem is not even acknoweledged. Nvidia themselves said it's not a driver issue but an issue with the game. Meaning only PA can fix it. 

Here are links displaying and discussing the issue:

i kinda tryed every workaround but i still got the flickering too sadly but if i play on High "texture quality" and on "Lowest/optimal" graphics i dont got the flickering effect xD 

Bump!

Crimson Desert had an almost identical bug. It was fixed within a couple of weeks. Surely the devs can take the time to fix this bug that has been around for over a year.
