My thoughts on 2.1's pathtracing
Okay so, the ghosting is gone — that's great. CDPR has switched from ReLAX and RTXDI, to using just ReSTIR.
I was playing with ReSTIR for a while before 2.1 released (you'll see the old commands in old versions of the mod)... While it doesn't have ghosting:
- it's slower than the 2.0 path tracing (it's running at half-res, which isn't necessarily bad)
- it's lower detail (imo)
- it's blotchy in some lighting conditions, especially at lower fps
- we can't control rays/bounces
- it can't be made super fast like the previous Fast versions
I'm keen to hear people's thoughts and experiences. I'm on the fence about disabling ReSTIR and re-enabling the tweaked ultra+ PT from 2.0. For these reasons:
- on high end systems at DLSS quality, there is barely any noise or ghosting (see the front page video)
- on lower end systems, Fast PT can be made... actually fast, and people seemed to appreciate this
- on Full... idk... maybe ReSTIR is appropriate here?
Either my game is bugged or we have very different standards. Ghosting is still very noticeable but not quite as bad as before. I'd still rather play with it off because it's still ruinous to the overall image quality.Ghosting is hugely better from the testing I've just done. To the point where I'd say it's no longer an issue worth mentioning.

3440x1440. Either DLSS Quality or DLAA. The moment I flip the Path Tracing switch, I see ghosting.Maybe different resolution and frame rate?

I play on a 4090+13900K+32GB RAM.
There is a video but more material would be better.Any comparisons of ReSTIR yet?
I don't think they are, when actually playing and moving somewhat quickly i'm noticing the lighting delay alot and I am kind of happy i finished it with the old PT mode. Even that area with the coloured lighting they used to show how RR made the whole area change colour when I ran through there the other day it seemed to be like the old none RR way again i.e the lighting wasn't colouring the walls/ground etc again and I did have RR on. I havn't been back to look at it properly to confirm that observation though.Differences mostly inconsequential

The part I was talking about is the one they used to show RR, i'll link the video timestamped. I probably shouldn't have said not colouring the walls/floor because yes it still does, it's just no where near as vibrant/noticable again. The current version with PT and DLSS/FG/RR all on looked closer to the 3rd slice without RR on. @pjbliverpool seemed to agree, i'll try grab some video and do a better comparison but I don't have a video editor so I'll probably just have to throw them up as 2 seperate videos.I don't really understand what you mean. Just made this shot. The colors could change a little faster but they still appear.
