JRVR Status, Plans and Upcoming Changes
jmone:
@datdude, as Hendrik says, there should be no difference in the refresh rate behaviour between madVR and JRVR in regards to dropped frame caused by bitstreaming drift. One of the big benefits from my testing with JRVR is that, as it is more efficient, you can run stronger scaling algos. The first thing to work out is if your dropped frames are from the GPU hitting its performance limit (in while case you have to ease up on the algos) or if it is the occasional ones from bitstreaming drift.
datdude:
I watched it intently for several hours over several different MC 28 and 29 versions and the performance metrics were always low. Can’t remember what they were but they were lower than madvr. And yet I would notice a slight visual stutter and then check the stats and sure enough there were dropped frames. I tried using the lowest possible settings which of course helped the performance numbers, but it still dropped frames. I tried non-bitstreaming and never had any issues. Madvr basically never drops frames and I never notice it. Maybe it is because I’m on an AMD, who knows.
Open to any other suggestions though.

I don't have any experience with AMD :(.
- If you are seeing 1 drop or repeat every XX Minutes when bitstreaming (and none with decoding when using Video Clock) that is the auto clock drift and should be the same on any Video Renderer. The only way of fixing that when bitstreaming is to play with custom timings.
- If you are seeing a bunch of drops and at more random times then it could be GPU slipping into and out of Low Power Mode. I see this on my 1660Ti and the only way was to either add more load (eg better, more intense algos) or in the GPU Control Panel select what ever the AMD equivalent of preferring "Max Performance".

Where do you set the custom timings? In madvr there is a tool for that not but not in JRVR. That’s what I was wondering if JRVR was going to add in. I think that is why I don’t get dropped frames in madvr.
jmone:
Custom timing are system wide (eg not just madVR), and are created by the GPU SW or 3rd parties like CRU, madVR etc. Once applied all applications are then using the new timings. So if you have one created in madVR then they are also the set of timings all apps (including JRVR) will be using.
