[2019] GPU Requirements for 1440p@60 FPS?

Unfortunately we can’t really give a guaranteed yes/no on this. There are a lot of factors that go in to how well the game runs. That video card is above the minimum requirements and should do fine. We have many performance improvements still coming down the pipe (Unity 2019.3 was just released 2 days ago and we’re upgrading asap).

I think that an RX590 is a great choice for video card and should serve you quite well. Other components in the computer or software that might be running in the background could cause a computer with an RX590 to not run at 60fps some of the time.

Personally, I have a GTX 1080 and can play on high settings with no frame problems.
Here is a comparison of GTX 1080 and RX 590.
