I'd appreciate your thoughts on a discovery, @ivyl : **Red Dead Redemption 2** requires `PROTON_ENABLE_NVAPI=1` and _also_ `PROTON_HIDE_NVIDIA_GPU=0` for DLSS to be correctly detected (even under its default Vulkan renderer,...

I've seen this on raytraced reflections under VKD3D on a number of UE4 titles - this is a nice clear example though.

I wouldn't be able to say...

I'm relaying this analysis from NVIDIA's compiler folk, so apologies if I'm mangling it in the process, but the conclusion (as I understand it) is that the generated SPIR-V is...

Thanks for the info. Reckon you're right! Compiler folk are still investigating, I'll comment here if they have further findings.

@doitsujin Thanks again for the new findings; forwarded to the compiler folk!

I gave this a spin. It successfully avoids the slow swapchain-thrashing that was previously reproducible in Spider-Man Miles Morales, Ratchet & Clank, and RoboCop Rogue City.
