The media player reacts. When I press stop button then it is pressed and the sound of the actual file stops playing. The video remains frozen until I close mpc-hc.

I would also add information that the system have two displays. One is the primary PC monitor. The second one is TV where the movies are played fullscreen. I operate mpc-hc from the main PC monitor taskbar (for this kind of test).

I also updated mpc-hc from 1.7.9.202 to 1.7.9.213. It did not change the behavior.

Unfortunately that wasn't it.
Thanks though.

I see, thanks.

so you get tearing with overlay mode?

I see, thanks.

Did you try playing with General Settings, checking/unchecking "use separate device"?

Crispen edges can look a little rough/aliased, which enhance detail brings out further. Nevertheless the two make my favorite combo with enhanced detail enabled under image enhancements. Thin edges seems to help with light haloing, looks better in upscaling refinement. In earlier versions I would normally prefer finesharp swhitching to lumasharpen if I saw artefacts. My sources are mostly live action. I always have Superres enabled in upscaling refinement.

I find Sharpen Edges + Enhance Detail is a superior combination than Crispen Edges + Enhance Detail. Edge enhancement is less obvious.

I don't like crispen edges either, with it alone image does look hardly shaper to my eyes and I don't find combinations with it very useful (rather combine SuperRes with a strength of 1 or 2 with sharpen edges and line thinning). It's also the only one of the new sharpeners that increases brightness.
(while sharpen edges on the other hand can decrease it a tiny bit).

It's useful at a glance.. Could you at least state the profiles that are running?

Try to tune the settings to get identical results. Which might not be easy. Obviously with higher strength there's a higher feature distortion.

Yeah I know. I'm not sure I'd call it necessarily a quality difference though.. but I'll see what I can do.

"thin edges" might be an algo which was originally aimed at anime, but it's deadly useful for refining upscales, too, so it's really a very general purpose algo. While line darkening seems to be only useful for anime content to me? This might be an algo most suitable to be run in custom shaders?

Fair enough..

Yes, I occasionally get tearing on applications that don't use madVR, like Outlook.

Thanks for the suggestion.

Yes, I tried all the four possible combinations involving use a separate device for presentation and use a separate device for DXVA processing.
Even these didn't make a difference.

madVR crashing MPC-HC x64 after Windows 10 fall update(version 1511). Is there any fix?

are you running nvidia graphics? i ask cause on my windows8.1 everytime madvr crashes mpc-hc the traceback shows it to be an issue with the nvidia drivers

I really can't spot an enormous difference while comparing "crispen edges" and "sharpen edges" with 1080p content on a 1080p display when it comes to sharpness. It looks like there's indeed a difference when it comes to brightness. "Crispen Edges" seems to brighten the image, "Sharpen Edges" does nothing of that kind and that's why I personally favor "Sharpen Edges". "Shapren Edges" produces clearly a more natural looking image to me. There's just an enormous drawback. The algorithm consums about 7ms of render time on my GTX 960 (not OC) and that's just too much in combination with my other settings I don't want to adjust.

It would be great if it is possible to optmize the algorithm so that is just needs about 3ms of render time, maybe 4ms. Hey, at least I'm free to dream.

I have a question reagarding DXVA2-copyback decoding. Would there be a huge performance gain if I replace - say a DD3-1300 CL 9-9-9-24 RAM - with DDR3-1600 7-8-8-24 modules?

I found the problem. I have 144hz 3d vision monitor and after the new update 3d mode was ON under Windows 10 display settings(not Nvidia control panel) this was causing the player to crash.

I very much doubt it. Try downclocking or overclocking your RAM to get an idea of what you would stand to gain.

should be a GPU driver issue nothing you can do about.

Some more thoughts on SuperRes radius:
I think one should simply use a lower SR strength for very high scaling factors, e.g. not above 2.
With it, I think aliasing is not an issue with real content in the wild and with high scaling factor, the effect of SR subjectively looks stronger to me in general.
So imho a radius of 0.66 is fine in general and if one wants less aliasing but still a nice sharpness boost, SR strength of 2 should be combined with the new sharpen options (at least once they are more affordable).
I would find it really bad if the radius was higher, as I really like the naturally sharp impression when doing 1080p -> WQHD. I suppose a radius of 0.66 also looks fine with 1080p -> 4k, as the aliasing seems to depend on a very low pixel count of thin structures.

If you like sharpen edges cause it's more well behaved then we there's no disagreement. Subjectively crispen edges is more visually pleasing, especially if the source is clean.

I'm not so sure about that, but let's wait and see.

There's another isssue with those interlaced DVDs since the introduction of the automatic switch to DXVA scaling:
When playback starts the clock deviation is heavily off, maybe 10^6 % or so, and the DVD essentially hangs for 10 to 20 sec until this value goes down to an acceptable level and plays fluidly thereafter.

hi there madshi. first time I'm posting here but I'm using your VR for a long time now. I was playing around with the new implemented sharpen agorithms and so far I'm pretty satisfied with sharpen and crispen, both at default values. the effect with superres is too subtle though for my taste, but maybe my display resolution is too low for the filter to be useful. I usually watch 720p content with a native screen resolution of 1680x1050. regarding luma and adaptive sharpen, I also don't see much use for them. I can't imagine content where I would prefer them over the new four ones.

anyways, I wanted to draw some attention to a new developed downscaling algorithm by ETH Zurich which is called "Perceptually Downscaling" which gets pretty amazing results:
https://graphics.ethz.ch/~cengizo/imageDownscaling.htm

I think that could be a gread addition to madvr. according to the paper the performance of is pretty good (they implemented it with matlab) and it should be possible to execute it in realtime. it seems that they didn't publish the code though but the algorithm is explained in the paper and presented in pseudo code, it only consists of convolutions and sums.

[huhn]

not sure about this downscaler. is sharper than bicubic but terrible aliased at the same time.

just look at the hair.

the comparison algorithm are pretty weak to say it friendly.
