Well isn't this on their to-do list? I mean it's not like they are not going to try & improve things.
I will be getting a new GPU & CPU when they are out hopefully this year, but i play other games so its going to be justified.
If recent rumours are true raster performance gain is going to be 40-70% of 20 series, i can't see how that is not going to help DCS in some way. So with a new CPU & vulkan eventually arriving That could see DCS being more playable in VR WITH LESS SHIMMER & much better frame rates.
I don't think DLSS will be possible in DCS. DLSS 3.0 is rumoured to be easy to implement but you need TXAA which i believe is not an option for DCS correct me if im wrong.
