set this to "only if scaling factor is 4.0 (or bigger)" and see if it still happens.

Yes! That fixed it. No frames are now being dropped

Thanks huhn.

So does that mean that MadVR was trying to quadruple the frame size as it was slightly less than 1080p and then downscale it again?

yes and if that happens with "let madVR decide" i see this as a real problem and it should be changed to at least 3.0. quadrupling for 20 missing pixel is just a total overkill.

just my opinion.

I agree. That seems like a weird edge case with a non-standard resolution but one maybe madshi can look at.

I agree, quadrupling for less than a 3.0x upscale is total overkill, and even a negative at times. However, I thought "let madVR decide" for quadrupling was 2.4x so quadrupling should not have activated.

My 4k display is 8bit + frc and I can't work out whether I should be setting MadVR to 8bit or 10bit.

Would there be any obvious downside to selecting either in this case?

madVR doesn't care about CPU core numbers.
But what about system memory or does it matter? I'm thinking about getting the newest Surface Pro equipped w/an i7, Iris Plus 640, and either 8GB or 16GB of system memory. Going to be using it mainly for the usual stuff, internet, email etc and watching my blu-ray collection on my TV via the display port and a little video encoding w/BDRebuilder. Any help/suggestions would be greatly appreciated. TIA!

8GB Memory is plenty. A Surface Pro system will be fine.

I have a small problem and not sure how to describe it.
Im not sure if its an issue with my JVC X9900 that I resently changed to from a JVC X9500.
I had never seen this artifact on the X9500.
I have all processing turned off on the X9900.

The issue comes about only accasionally when the screen is black and the next image fades in. The look of the fade in kind of goes into double ghosting, or the look of water/waves moving across the screen.
I just tried to video it to show you guys but it doesnt show up clear on the video.
The artifact appears for a few seconds after the text "The Mountain Between Us", however you will not really see it on this video.
https://youtu.be/TmhsoMWAVs0

I use the 1080Ti card and upscale BDs to 4K using NGU sharp. I have tried NGU soft, NGU AA and many others, the artifact is still there. I have tried dont render frames during fade in and out, doesnt help. Ive spent hours playing this scene over and over when turning almost evrything off on madvr and on the proj, it doesnt help. My rendering times are very very low, round 17ms, I have no dropped frames...

It might just be the projector, as I say this never used to happen with the X9500. I dont think I ever see this during a film, maybe only at the start...

Thoughts please?

the ghosting is easily visible in the video. but not sure if this is the issue you are talking about.

can you make me a screen of the OSD?

2.4 default for double again mode (or NGU AA). For direct 4x "if any upscaling is needed" by default.

Thank you for your fast reply, 8GB it is. Will save me a few buck too. Love this forum... and madVR!

You really cant see the artifact Im describing in the video. What you are seeing is not the problem described. The video is not displaying this ghost/double image on the fade in after the text "The Mountain Between Us"

I really think its an issue with the JVC X9900.

This video has the OSD stats. The top display section 23.97??? is missing from the OSD with my black velvet screen masking.

make sure your device of choice doesn't have thermal throttling issues(sadly not uncommon for small factor intel devices) and you are not going to do more than FHD.

I would like to know how to use the control function for the videoprojector, in particular I would like at the end of the playback to return to position 1 of the lens. thank you

Mine is also 8bit+frc (see in the signature): use 10bit in madvr.

In regards of refresh rates, which one is the better option - to overclock your monitor to be used 72hz all the time (no switching), or to use the default 60hz, and to create 48hz and madvr to switch it on when needed? I don't like smooth motion at all :/

If you donīt like smoothmotion, use custom refresh rates according to your video material and according to the capabilities of your monitor.
For 23.976fps movies use refresh rate 23.976Hz OR 47.952Hz OR 71.928Hz OR ... Which one doesnīt matter, use the one your monitor accepts.
So a full set of refresh rates for all possible common movie frame rates would mean e.g. 47.952Hz (->23.976fps), 48.000Hz (->24.000fps, 48.000fps), 50.000Hz (->25.000fps, 50.000fps), 59.94Hz (->29.970fps, 59.940fps), 60.000Hz (->30.000fps, 60.000fps). Or other multiples if your monitor doesnīt accept these ones.
72Hz with no switching only works correctly for 24.000fps movies, so thatīs no option when wanting judder free playback and not using smoothmotion.
The default 60Hz are usually in reality 59.94Hz, so with your default "60 Hz" and 48 Hz you could only playback 29.970 fps, 59.940fps, 24.000fps and 48.000fps correctly.
It depends on your video material, but for all possible scenarios you would need the 5 custom refresh rates, see above.
I wouldnīt use the term "overclocking" in this context. Ok, a colcok of 72Hz is higher than the "default 60Hz", but there arenīt the same principles like overclocking e.g. a GPU or a CPU (which gives more temperature and more electrical stress on the components). A monitor accepts a given refresh rate by the computer or not. A higher refresh rate doesnīt do any harm or is dangerous. The worst thing that could happen is, that you have to do a safe boot because of getting a black screen when using a custom resolution your monitor doesnīt accept. But thatīs it. Use whatever your monitor can display correctly.
