Just to be clear, the game runs great with the DX11 on my Steam Deck Oled. The only downside is that i find out that you can actually enable HDR by following this guide and it works GREAT… until it doesn’t. The guide itself work with no issue but to enable the hdr option I have to run the game with DX12, and dx12 ( tested with or without mods) cause some random drop to 1 fps in some point of the map, usually in the space between rooms. I tried both Proton Experimental, and GE Proton but the lags keep happening. Anyone have a fix to that?
Do you always get the lags when changing between the same rooms or only once when you enter a new area? Might be due to a new shader needing compilation.
I don’t know if VKD3D has anything similar to DXVK_ASYNC. But that’s the direction I would look in.
