Vulkan runtime on not hw accelerated GPUs (1660/1660 Ti) are slower than Q2RTX one (but still working) FSR 2.1 is already available, please update *there's a strange bug about textures: if I shoot - with the shotgun - a black wall ('cause of shadows) it lights up.....and remains bright until the viewport changes (rotation, etc).

It's amazing that it works on 1660, I would try to optimize, if I had that hardware in addition
I just forgot to rename the button, FSR 2.1 is there
This is a temporal lag, and temporal accumulation should be tweaked, but it's quite hard. There's a chance that the current algorithm will be replaced

It works well on the 1660 Ti, but @1280x720 I got 25 FPS literally everywhere :| (Q2 RTX 40 FPS but in Q2 we got more tweaking options like the global illumination complexity and so on and conveniently in the graphic options menu)

sultim-t commented 1 year ago

I didn't expect 25FPS. Is it without AMD FSR? There's direct dependency between render size and performance, so AMD FSR is a must in your case :)

donizettilorenzo commented 1 year ago

Yes, exactly. There's why temporal upscalers are essential to raytracing via classic shaders (and why I did ask to update it :p )
