Hello, I was playing the game on Tuesday and it worked fine on my computer on the balanced setting. Then after the update it was laggy and not playing well until I turned on Ultimate Performance Mode and then it was playable. I've got a Geforce RTX 4060 and a similarly high level CPU so I shouldn't be having problems with it. I am however using Arch Linux so that might be part of it but like I said, it was working fine until the patch.

there was a new setting added called FSR frame generation that's a toggle. You might try to turn it off.
