Read the last few pages of that thread and look for NeoXP's posts that contain his settings. That'll be a fairly decent place to start.

So I bit the bullet and jumped on the 113 train. It really does look good!

I am using: D3D11 (native), Chroma @ AA Medium, Luma @ Sharp High

**ONE important thing I noticed is that my video ram usage is VERY high. 3924MB (out of 4GB) so I am pretty much peaked - which could result in some playback issues on some scenes.

Is there a way to reduce video ram WITHOUT reducing quality in any way? Something like reducing the amount of frames presented in advance to 4 instead of 8?? Does that help video card ram at all? Any other ideas would be appreciated!**

Try lowering the GPU queue size and see if that helps and if it breaks anything.

I recommend not setting frames presented in advance above 3 so that is a great way to reduce memory usage.

Windows 10 doesn't seem to like too many frames presented in advance, it can cause un-reported (in madVR's UI) frame glitches/stutters.

Like SamuriHL suggested six or even lower GPU buffers works well on my system. This has the biggest impact on memory usage.

Hi, just wondering if there are any advantages or pitfalls not using FSE, havent really used it for a while now, hasnt been required on AMD cards for HDR or 3D for a while

When using native hardware decoding, reducing the decode queue (still mistakenly called 'CPU queue' in settings GUI) also helps reduce VRAM usage.

@mclingo - There is really no reason to use FSE. Since MS added "fullscreen optimizations", FSE only works correctly if you disable this feature in the compatibility settings of the player.

Like SamuriHL suggested six or even lower GPU buffers works well on my system. This has the biggest impact on memory usage.
I changed my settings as follows:
CPU Que - down to 8 (does lowering this help with rendering timing?)
GPU que - down to 4
Windows Frames to Present ahead - 3

This definitely reduced the video ram. Just a little bit, but that was all I needed to keep myself from maxing out my video card's 4GB.

I was even able to get chroma back up to AA medium. Although my rendering time is skating the LIMIT at between 36 and 39ms. I did notice it 'steal' one of the read ahead frames a couple of times - but they did their job, and no lost frame. So far at least.

I know I can reduce the Chroma to LOW if needed, and that will shave those rendering times down to 33.

Speaking of which, I played a 25FPS 4k file (a planet earth II) - and just this little bit of extra FPS was enough to tip the scale. I HAD to lower chroma to low in order to watch that file.

Separate Question: Does LUMA upscaling only come into play when actually upscaling? Like watching 1080p on my 4k screen? I only ever see it in CTRL-J when I am watching 1080p content.

Yes, unless you're insane and upscale 4K->8k and downscale it. (Don't ask. no, I'm not one of those people....yet). I'm glad you got it working well.

Now I can break your heart. Unfortunately, since you are right on the edge for 23.976fps, there's an almost 0 chance of playing 60fps UHD movies on that card without dropping frames. At least not with these settings. Trust me, I have to make a ton of compromises myself with the 2070 to do it. Fortunately (?!) there's not a lot of 60fps UHD content just yet, but, be aware of the limitation.

Will lowering the CPU que even more help with rendering times? Or is that only RAM?

Someone suggested ticking the Compromise Tone & Gamut box - is that something worth trying? Makes me nervous when I see the 3 read ahead frames getting used.

I tried to play a 720p 60fps file the other day (a sporting event) - and it didn't like that at ALL.. Thankfully I have MPV Player to help with those files. MPV player does basic HDR to SDR, so uses very little GPU.

Only RAM.

If you need faster you can tick it, if not it isn't better.

You might setup profiles for 720p60 or use much faster luma scaling options. You are probably doubling it twice which is very hard but you don't need to loose all the benefits of madVR to solve it.

the CPU name is misleading it's Vram for native decoder.

don't go below 16 as far as i know these frames are actually used by the decoder and 16 ref frames are a thing.

i have no proof for the need of 16 for ref frames.

So.. checking the box for compromise on Tone & Gamut made a HUGE difference. HUGE.

From almost 40ms rendering times to 29ms rendering times.

Was enough of a performance savings that I was able to up the chroma to AA HIGH again. Now hovering between 33 and 35ms rendering times.

The savings was enough to even play the 25fps planet earth II file without any playback issues.

I feel like I am getting pretty damn close to finding the optimal settings for my GTX 1650 Super. I may have already!

Any opinions on the Soulnight's Mirror contrast curve? I am liking it so far.

You'll DEFINITELY need profiles for 60fps content. I do for my 2070, as well. There's all kinds of different compromises you can create for your different profiles.

I tested with a 9 ref frames file and madVR queue to 4 and it decoded just fine.
Pretty sure this only represents the number of 'usable' frames madVR asks the decoder to output and is independent of reference frames which is stuff internal to the decoder.
Of course reference frames for decoding use additional RAM too.

@LordX2... you will at some point need a good set of profiles so that you do not need to go in and change settings for different content (res, frame rate, etc)... Here is a copy of mine, I have not edited it for some time and I am sure I have a lot of duplicate settings now... The wonder of upgrading to a much faster card, higher settings can go a lot further :P

Code:
if     (srcHeight < 721)  and (deintFps < 25) "720p23"
elseif (srcHeight < 1081) and (bitdepth > 8)  "1080p23 HDR"
elseif (srcHeight < 1081) and (deintFps < 25) "1080p23"
elseif (srcHeight < 2161) and (deintFps < 25) "2160p23"
elseif (srcHeight < 721)  and (deintFps < 26) "720p25"
elseif (srcHeight < 1081) and (deintFps < 26) "1080p25"
elseif (srcHeight < 721)  and (deintFps < 31) "720p29"
elseif (srcHeight < 1081) and (deintFps < 31) "1080p29"
elseif (srcHeight < 2161) and (deintFps < 31) "2160p29"
elseif (srcHeight < 721)  and (deintFps < 51) "720p50"
elseif (srcHeight < 1081) and (deintFps < 51) "1080p50"
elseif (srcHeight < 721)  and (deintFps < 61) "720p59"
elseif (srcHeight < 1081) and (deintFps < 61) "1080p59"
elseif (srcHeight < 2161) and (deintFps < 61) "2160p59"

i know for sure that it affects decoding VP9 with to many frames it will corrupt the image that's why it's limited now.

So, looking at the settings I attached on the last page - is there something other than Chroma I should have upped?

I went from Chroma AA Low to Chroma AA High after ticking the compromise for tone and gamut, but if there is something else that would have made more sense to crank up rather than chroma, I am all ears.

Clock Deviation.... it is the one thing left that will get me a dropped frame every now and then.

When all settles out, it estimates 1 dropped frame every 1.07 hours.

This frame ALWAYS drops. The buffer doesn't dip or anything - the frame just drops.

My refresh is damn close to source - 23.97612

What else can get clock deviation tighter? If I could get it over 2 hours - I would be set.

Sorry for offtopic, but how is this effect called of the background:
https://www.youtube.com/watch?v=07FYdnEawAQ&t=47

I thought it is posterization, but I am not sure about it. I could also be banding. Do you think this "is a bug or a feature" of the video, I mean is it intentional?
