Hello @jacek.wielebnowski and welcome to the NVIDIA developer forums!
Unfortunately I am not able to immediately answer your question, but I will ask the DLSS experts internally for their input.
Could you please share the (zipped up) contents of your log file directories for them to have a look at? Their locations are stated in your output snippets above. Also, what kind of Windows container (VM or docker?) is this and on what host OS are you running?
In the meantime a quick checklist:
- Did you try to update UE to the latest release version (5.0.1)?
- I assume you downloaded the latest DLSS UE plugin already from NVIDIA?
- Are you running the latest NVIDIA driver?
Thank you!
