I’ve got a good spec and a 3080, I use a 42” Samsung tv in 4K. After lots of messing I’ve locked the card to 30hz which is by and large very stable in almost all environments and with most setups/aircraft and high/ultra settings at 2560x1440. Looks and plays great, I can get 100fps in some areas but it’s no good when the FPS drops.
Hopefully dx12,and dlss will be used in the future to optimise FPS. I can’t image a solid 60hz but we’ll see.
