What does it means? I don't think DLSS can work as proper DLSS on 16xx series or yes (just like DXR/VulkanRT without RT cores)?
Thanks!

Hi,

As it says lets you use real DLSS on 16xx series cards. Usually it's slower than native until balanced/performance but worth checking.

To double check you can enable DLSS overlay with reg file from NVidia's DLSS repo.

:o Just out of interest, how is this even possible? Are there tensor cores in the 16xx series? Or it's another kind of implementation?

Hi,

I am just hijacking response of nvngx and return DLSS supported to nvngx_dlss.dll. According to performance level most probably some kinda emulation happening but TBH I am not sure.

Can you test it in QuakeRT? I get the upscaling working but the game crashes after some seconds.

I noticed that too, as a workaround it works nowmally on windowed mode. As far as I can see 2.1 has issue with colors tho
