I can't see anything wrong in the log, except that the rendering of the first two frames takes 113ms and 56ms. All remaining frames are rendered in < 5ms. Not sure why this happens.

Does madVR v0.85.1 behave differently on your PC? You do not have that 0.5 seconds of transparent window with v0.85.1?

If you don't find these controls useful, you don't have to use them... I'll probably not use the "display color control" settings myself, but some people might find them useful, what do I know. I've added them for completeness sake and because some displays do not have good controls for that.

Well, you can press the key and hold it.

madvr is now the best renderer out there for me..nothing can beat it in tearms of quality, functionality and more..

It's done with the highest precision the GPU allows (32bit float). I'm not sure myself how useful such a contrast adjustment is, but it does exactly what it's supposed to do (from what I can see). Maybe nobody will use it, but it's there, because all the color control dialogs have a contrast setting, so I need to offer some algorithm for that.

With 1080p at 2x, I get 6ms for Bilinear Chroma & Luma.
With DXVA2 I get a large spike at the start of playback (over 1100ms) and then it settles at 56ms.

DXVA2 also has worse image quality than Bilinear Luma & Chroma in madVR due to the increased ringing and aliasing from the sharpening used.

With 1080p at 2x, I can run Bicubic 75 AR Chroma with Lanczos 3 Luma at 37ms total, or with Mitchell-Netravali Luma for 27ms.

Ok, seems DXVA scaling is not all that useful for NVidia users. But for Intel users, the situation is very different, I think.

From a two minute sample clip:

DXVA2 N: 84% GPU, 72% MCU, 24% VPU peak usage.
DXVA2CB: 83% GPU, 71% MCU, 20% VPU peak usage.

That's correct. Hmmmm... I wonder why Native consumes more GPU power than Callback. Anyway, what does CPU usage say? Is it higher with Native, too?

Gamma change would be "brightness", not "contrast".

Well, you don't have to use the madVR brightness/contrast settings. Just set them to 0, then madVR will even disable the shader code, so there's no disadvantage for you.

In this case, yea, I think film mode would be appropriate, but I can't get it to work without changing the fps to 50p. Do I have to turn off deinterlacing first?

The problem is that deinterlacing in half framerate will also seriously damage deinterlacing quality. So I don't think offering that is a good idea. Film mode only works with software decoding (or CUDA or "copyback" in LAV). It doesn't work when using native DXVA2 decoding.

I think this is an important achievement for madVR to be useful on less powerful GPU HW.

And colors are alright? FWIW, this way you only get 8bit YCbCr to RGB conversion with the current Intel drivers, unfortunately. I hope this will be fixed with a future Intel driver version. And yes, chroma upsampling is done by Intel/DXVA2 in this configuration, too.

The edit boxes are grey, but the left/right buttons should work.

Here's a list of currently supported special keys. Your keyboard may not have all of these keys:

Back, Tab, Clear, Return, Pause, Break, Esc, Space, PageUp, PageDown, End, Home, Left, Up, Right, Down,
Select, Print, Execute, Insert, Delete, Help, Win, Apps, Sleep, NumPad0..9, Multiply, Add, Decimal, Substract, Divide, 
F1-F24, NumLock, Scroll, BrowserBack, BrowserForward, BrowserRefresh, BrowserStop, BrowserSearch, BrowserFavorites, BrowserHome, 
VolumeMute, VolumeDown, VolumeUp, MediaNextTrack, MediaPrevTrack, MediaStop, MediaPlayPause, 
LaunchMail, LaunchMediaSelect, LaunchApp1, LaunchApp2, Play, Zoom

I can't seem to pinpoint the "type" of video it does this too either. It just seems random. If it matters, I'm having this problem on both my GTX 460 and my Intel HD3000 (Jinc4 on the former and Spline3 on the latter).

No, this is not normal at all. Maybe you have some other applications which use the GPU? E.g. some newer browsers do. Or maybe some software like SETI running in the background?

madVR "brightness" control = Gamma adjustments.
