Wow big suprise, it seems like nvidia drivers and game update done the job for me.
i7 3070ti 32gb ram - 2k all ultra except hd textures - playing for 2 hours and bug isnt showing up anymore.

Last far [censored] game I paid for. More than two weeks after release and still no update...

@kalitheman Mate you should try going back to 471.96 because I am running a very similar setup like yours (RTX 3070 i7 32GB) and I am able to play 2k all maxed out with RT except HD textures and bug isn't showing up anymore. Even if game is eating more than 6gb vram all the time for me.

I have done some more testing now and after two hours of playing bug didn't appear at all. I have RTX 3070 and after going back to 479.16 driver I am able to play at 1440p all settings maxed out except HD textures and the bug isn't coming back at all

It looks like rolling back to 471.96 nvidia driver solved the issue for me. To be fair framerate has dropped about 15% but I was testing it for 40 mins and bug didn't appear so far. Before I was between 80 and 100 fps and now I am about 65/85 on ultra 2k without hd textures. I'll do some longer testing later on.

@kevinsyslo2 Bug appears even without HD textures, resolution or quality presets doesn't have anything to do with that.

I am wondering how long will it take for them to fix this mess...
What a crap company
