because you changed the scaling rules to 4x always.

Oh right, I think I understand. So is this just an issue for frame sizes that aren't clear divisions of the display size?

EDIT: scratch that, I'm really not sure I do understand this at all.

Is there a good resource for getting my head around scaling in MadVR? I thought I had my head around it but these couple of films seem to behave differently to everything else

Yea, your rendering times are off the chart as huhn said likely because of the scaling. That's an odd source resolution.

The thing is my scaling settings aren't set up for anything crazy bearing in mind I have a GTX1060.

Well now I'm very confused because I didn't do that at all.

I had NGU sharp set as my luma upscaler with high on the doubler. Everything else is set to let MadVR decide. Is that really so stressful for a 1060?

The only way I can prevent dropped frames is by setting it to NGU sharp low

Is it possible the peculiar resolution is the problem?

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!
