I don't think the requirements have changed, but I had major issues with patch 6 on the high end of things. Uses a lot of RAM and prone to crashing. I switched to DirectX and it was playable.

Then I upgraded my processor from an i7-5960X to Ryzen 9 5600 and the game is so much more smooth. I don't know if it's a problem with running DLSS or lack of optimization but I imagine it will smooth out by release for the system minimum.
