Pure crap

[JCKödel]

1) Doesn't obey which is my main monitor (I have 3)
2) Doesn't support 4k (initially the screen was 4K but the mouse was 1080p, so I could not click on the option)
3) After setting resolution, the game just crashes.

i9 12900KS, RTX 4090, 128Gb RAM.

I'm running on a 5900x + 6700XT and the engine used or the way it was coded is done in such a way that my GPU usage is only around 50-60%. It's putting most all the load on my first core and thread and CPU bottlenecking me around 40-45fps lol.

I know that doesn't help and your GPU is multiple times better than mine, but yeah... game has some issues.

However, I'm running 1440p all Ultra Vsync off with the "120fps cap" (max setting) and it's not giving me any problems.

In your case, I'd try unplugging the two monitors you don't want to use and try again.

Not only try to unplug, just do it.
