JRVR MC29 Testing [Pre-release / Old]
jmone:
I've started testing using Auto Select Tone Mapping, and it looks GREAT, but I'm getting some issues.
- What is the Default for Auto Select?
- I'm seeing Brightness Pulsing after a scene change
- Is it more expensive to tone map a 4000nit video (UHD 23.976 Fury Road) than 1000nit (UHD 59.94 Gemini Man)? Fury Road is dropping frames and is almost twice the render time on my 1660Ti than Gemini Man.... or is nvidia doing some power mgt thing?
jmone:
Forget the performance question. A reboot fixed the issue with frame drops on Fury Road.... and render time is now half Gemini Man (which is what I'd expect). Got to love Windows!
On the Brightness Pulsing, it is related to Peak Detection. It pulses when it is Checked and Does not pulse when it is unchecked.
Hendrik:
If you have delayed peak detection on, turn it off. Otherwise it's just what it does, if the image brightness changes, it compensates, which in extreme changes can be more visible then otherwise.
But with the new tonemapping, peak detection should be needed much less now.
jmone:
Delayed Peak Detection was OFF. With Peak Detection ON (and Delayed Peak Protection OFF) I'd see a double pulse after some scene changes as it seemed to rapidly adjust one way then back again. Anyway, I'll leave it OFF for now.
jmone:
I'm very impressed on what JRVR can do in such a short period of time... striking a great balance of performance and quality. Who would have thought a lowly iGPU in a NUC could handled HDR Passthrough on UHD 59.94 content, or that a 1660Ti could have all the goodies at Max, Tonemap ... and still have plenty of headroom?!
The other benefit that should not be underestimated is that it "works out of the box" with little need to tweak 100's of combinations/permeations of settings with madVR. While I'm sure hard core videophiles will still prefer madVR to extract the very best results for a particular setup, the fact is that JRVR is far more efficient, hence runs on a much wider range of HW, and yet manages to produce a great image. It is an enormous step up from EVR, and for most of us, indistinguishable to madVR without the need to fine tune.
Well done. I don't see a reason why JRVR should not be the default for RO.
