Is there anything else I should consider?

Unfortunately, you cannot use 398.11/385.28 with RTX cards

madVR has lots of algorithm adjustments to fine tune. We know you've adjusted them. So does PowerDVD. Did you adjust any of them? Even with the algorithms off, my results using PowerDVD and madVR don't look anywhere near as bad as the pictures you posted. I sure hope it's your camera.

madVR doesn't need to hide from proper comparison.
you won't believe how much work it is to turn an image to look like crap.

i would have done a proper comparison already if i would even dear to give pdvd a single Pfennig and i have no doubt in my mind madVR will win not even a challenge.
but this needs to be done with proper screenshoots and at least the same frame.

This does matter. My only issues personally were with HDR when using an RTX card. But on another thread it seems some cards have the issue I did and other do not.

Some people have had problems with HDR content on certain RTX cards where there will be judder which is unrelated to clock timings and repeated/dropped frames. It appears as a visual judder or hiccup during playback. No setting I changed corrected the issue. Swapping to the GTX 1080 in my desktop pc (and downgrading my drivers) removed the issue completely so this is no longer a problem for me. I'm not sure if it is related to some of the new beta builds of MadVR, specific cards, etc. I also noticed that it always happened at the same spots during playback. I've seen people who have RTX 2080s say they've seen it as well as myself who had an RTX2060 at the time. So unsure what the root cause of the problem is. It only happened during HDR playback wile using an RTX card and never on 4K SDR or 1080P playback.

I see thanks, my RTX card is in my desktop with no HDR so looks like a non issue for me.

I have solved the problem simply by using FSE (Full Screen Exclusive mode), that took care of the micro stutter completely.
I Quote myself to have some traceability of solutions for the micro stutter with RTX 2080 graphics cards.


I can confirm and I think it was @Soulnight who wrote that by changing the Vertical sync to "ON" in the Manage 3D settings in NVIDIA control panel completely solved the micro stutter I had in Fullscreen Windowed mode.

So the two solutions that is working for me is to enable automatic fullscreen exclusive mode in madVR or set Vertical sync to "ON" and continue using enable window overlay in madVR. Both will solve the micro stutter I had when using my RTX 2080 graphics card.


edit: adding a picture to better illustrate the vertical sync change needed.

Great that it also worked for you.
It also worked for everyone who had the same issue in the german madVR/HTPC facebook group.

Onkyoman pointed that out to me earlier but it didn't change anything for me unfortunately. Glad there are things that are helping some people! I'm just happy I had an alternate video card I could use!

wanting the Radeon VII. I am over Nvidia overpriced overhyped gimmicky bs


Can anyone tell me from the HTPC user point of view if there are any pros and cons you all can give me regarding amd or nvidia? (all fan-boy comments aside please). Just really wanna hear some honest non biased comments from actual users. I use Madvr all the time for hdr 10bit rips. Any features I would be missing out on from one to the other? etc.



Thanks in advance

So right now I use Ycbcr444 on the GPU, madvr is Auto and projector is also Auto and that works. But it is not RGB

I have HTPC with RTX 2080 and is using a JVC X7500 projector.

Any idea what setting I might have done wrong. Do you need more info please let me now.
Anyone who can help me out.

When watching 1080p movies upscaled to 2160p I get RGB 8 bit full, but when I watch 2160p I get RGB 12 bit limited, Ycbcr444 limited. Can't get RGB 8 bit full when watchng 4K

madshi gave a hind for the use of tensor and a clear recommendation RTX cards because of that.

and yes the RTX cards where known to be over priced until AMD joined them with the VEGA 7 which is just a vega refresh with a RTX like price tag and no real new feature if useful or not. these turing cards have quite some potential which may never get's used and i'm clearly not talking about ray tracing here...
how can nvidia over price there cards if AMD does the same? worst possible outcome...

nvidia has currently a major "bug" (they may do it intentionally wrong which makes it even worse) with HDR pass through.
the AMD user number is currently low for madVR because polaris can't deal properly with NGU so major driver bugs are less known. i'm not aware of any that can'T be easily workaround.

what i currently do is not getting any GPU right now and hope navi is a good architecture and tensor cores are not needed for whatever new thingy madshi plans or i hope for cheaper nvidia cards not using an old manufacturing process. the release of vega 7 clearly didn't help me believe navi is going to be any good...

for gaming the 580 is the current go to card in it's price range if power consumption doesn't matter to you (a 1660 uses less then half the power).

TL;DR

wait for NAVI and hope it get's better but it looks like nvidia is the vendor of choice for madVR if you want to use all of it's features.

I agree with you in the 2nd part
Unfortunately, as huhn said, Radeon 7 is not meant to be a gaming GPU but AMD didn't have anything else to present this year (?) since Navi is hold back for now. Biggest issue can be power consumption and heat -> noise. If it was 2/3 of the price of an equivalent nvidia GPU, then maybe, but that's not the case. (They state that the new memory type is the really pricey one on it (compared to gddr 6) and AMD even loose money on the card! )

Hopefully Navi will be big. Under big I don't mean the fastest chips but an energy efficient powerful mid-range chip with a nice price tag. But who knows, we will see in time. If they won't announce it during computex then probably it won't happen this year.

I'm not telling to not buy one (you can send it back if you don't like it ), if you will then probably you'll be the 1st one with Radeon 7 and you can "benchmark" madvr with it

Interesting. Does your projector have HDR mode? If so, is it selected when 2160p content is used? Otherwise it doesn't make any sense.

Yeah right now isnt the best time to try to get an upgraded card. I was afraid you guys were gonna say to wait till Navi. I agree, I mean Ive had the 970 this long I can wait longer. If the 2080ti were reasonably priced I would get that but that price is just ridiculous. And not interested in getting a mid tier card as the 970 is fine at the moment. Thanks!

I have a RTX 2080 ti and was having stuttering both during 1080p playback and downscaling 4K HDR to 1080p. Regarding 1080p, changing the preferences in the nvidia control panel to "Prefer Maximum Performance" solved the stuttering issue, as it the card was not being taxed and moving back and forth from no load to load was causing the render times to jump all over the place. Just turned VSYNC on in the control panel, will need to do more testing regarding the 4K HDR stuttering. Definitely an RTX issue as I was having no problems with my previous GTX 1070.

It does select the HDR mode when playing 2160p movies.

Then that's the issue, ask around in the projector topics about this if you want to use the HDR mode of the projector.

The best result will come from converting to SDR, so there is no need to send HDR to the projector. That could simplify your issue, which affects many JVC projectors.

It actually makes sense. I had some settings in madvr before and all work fine withv the 8 bit.

But have made two profiles under my projector, a HDR and a BT709. The made a if line > If (HDR) "hdr" else "bt709" and since then I have had the problems. Was a guy who told me to do it like that, so that I could use the HDR profile on the projector., to take advantage of the BT2020.

The BT709 profile is right now set to passthrough HDR.

Before I used two profiles unde processing and the if line was this. if (srcWidth <2001) and the over way around >2000.

Onkyoman can you guide me a little here?

Just turned VSYNC on in the control panel, will need to do more testing regarding the 4K HDR stuttering. Definitely an RTX issue as I was having no problems with my previous GTX 1070.
Thanks for the update. I thought I remember "prefer max performance" does something with idle clocks? Like locks them at 3d clocks instead of idle. Not sure if that is true or not. I'll look more into it.

You can set it to "Prefer Maximum Performance" specifically for whatever player application you are using (MPC-HC in my case) in the nvidia control panel. Monitoring the clocks with EVGA Precision, playing 1080p content, it was about 1300MHz as opposed to bouncing around from ~400Mhz up to ~2000Mhz when just using "Adaptive" power setting. So not really any power or temp concerns playing 1080p content. 4K content, with the scaling settings I'm using, was pretty much using a bunch of the card anyway so I don't think the setting has too much of an effect in that scenario.

Render times are ~4.74ms at 1080p and ~27ms downscaling 4K to 1080p.
