Image doubling is set in Image Upscaling now, simply choose a doubling algorithm (super-xbr, NNEDI3, NGU). I recommend you test NGU for yourself, for 720p -> 1080p it is more subtle, but it is madshi's amazing new scaler that is very sharp but without artifacts. It runs quite well on the r9 290.

edit: DX11 is the preferred option for AMD GPUs. AMD just seems to like directX 11 more, there have been many user reports of issues with the various DX9 modes and AMD GPUs.
Thank you for the information. So , I set chroma upscaling-> jinc and image downscaling-> catmull-rom.
For image upscaling I set NGU with luma-> high, chroma-> high and algorithm after doubling, upscaling-> jinc and downscaling -> same as image downscaling(that is catmull-rom). http://prnt.sc/dtgdff
What is your opinion? Are these settings too much for generic use(watching movies)?

Output of 1080 movie: http://prnt.sc/dtgbf6
Output for 720 movie: http://prnt.sc/dtgaq9

Just one more question. I used to watch movies with letterboxing. So now that madvr can handle scalings in a better way than the player itself I want to know which is the best setting to upscale the non true 1080p files(like 1920x800) or the 720p files to 1080p to cover the whole screen.
If I use in mpc (right click)video frame-> zoom 1 I loose a bit from the edges of the film. If zoom 2 a little more. If I use touch window from outside I loose a bit more from zoom 2.
If I use scale to 16:9 TV people in the movie seem more streched (I don't how to describe it) and if I use zoom to widescreen I loose again part from the edges of the movie.
What is the best setting in your opinion or what is the most mainstream setting.
Sorry for my english again.

Thanks for this release, quadrupling looks great with SD content. Also please don't forget to add LL to OSD and adding an option to prevent auto quadrupling. Thank in advance for your hard work.
If you set the Chroma to normal just below the luma in the NGU option of image upscaling, NGU very high will be x4.

Thanks! That was my fault. I did not read what madshi writes in his post.

I currently have a GTX 1060 Founder's Edition with a 400 Watt power supply. While playing 1080p content with fairly high madVR settings I am pulling at max about 220 Watts total for my system measuring with Kill-A-Watt. From benchmarks, I've seen from Anandtech that the GTX 1060 FE pulls about 264 Watts while the GTX 1080 FE pulls about 335 Watts under load while running Crysis 3. Would I be safe to replace my 1060 FE with a 1080 FE for madVR duties, and if so, would I get a substantial performance increase in madVR using the GTX 1080 using the same 400 Watt power supply over the GTX 1060?

Yes, provided it's not a cheap PSU.

Yes, enable the settings you'd want to enable with the extra performance you'd stand to gain from upgrading and determine if it's worth it to you first, unless you plan on also using it for gaming.

Thank you for the answer. One more question. You mentioned that a cheap PSU would be bad. What would be the difference between different PSU brands if they all rated for 400 Watts?

Stability of the various voltage rails, component & design quality which affects maximum output and system stability. Just read a good PSU review and you'll learn everything you need to know.

Would someone tell my what are good settings for upscaling DVD to 1080p please?
Im projecting them to a large screen so want them to look as good as possible with few artefacts.

There's no single answer to this, and you don't mention what graphics card you're using, but try madshi's new NGU 4x (go back a few posts for how to enable). It's a bit too sharp for me, but might be just the thing for a projector.

Smooth edges seems to be broken with the 4x NGU step, doesn't show any effect then.

4x looks great to me - definitely better than doubling twice.

This is probably mainly because "old quadrupling" doesn't use 2x NGU very high. 2x VH can look better in regard of ringing than 1x VH + 1x high/medium.

Tis, noticed this last night. Reckon this should've been a test build rather than a proper release considering the implementation.

About RGB conversion

Hello fellas! I have a question. by default, Madvr convert video to RGB full 0-255 or RGB limited 16-235?

To connect the TV to the PC by hdmi, which is better RGB full or limited?

Thks!

A couple of questions please...
If you are using Image Doubling, you dont have to have the video card set to 4K do you?

Am I thinking this right for 1080 BD:
Video Card set to 1080p
1080 > Image Doubling to 4K > Down-scaling back to 1080p

This is still giving a better image for Blurays isnt it rather than 1080 > 1080?

the display expects the following RGB output levels: [PC levels (0-255)] This is what your display expects to receive. 'PC levels (0-255)' means “use a 16-235 YCbCr to 0-255 RGB conversion matrix” and 'TV levels (16-235)' means “use a 0-255 YCbCr to 0-255 RGB conversion matrix”. If the source is flagged full range either a 0-255 YCbCr to 0-255 RGB or a 0-255 YCbCr to 16-235 RGB conversion matrix is used instead.

no don't use the super sample "feature" from the GPU for that.

you need to check "activate 200% super sampling"

it is giving you a different image. that doesn't mean it is better or worse in general.

Sorry if Im not understanding it all properly as Im still a newbe

So this: no don't use the super sample "feature" from the GPU for that. = leave the video card at 1080p

And this: you need to check "activate 200% super sampling" = Im not sure what section that is in, sorry.

Thks! But, witch is better or the right one for the pc-tv connection? Rgb complete or limited?

Complete (full) range is preferred unless your display doesn't like it.
