Drivers are buggy enough even without multi-GPU.

Why it should be buggy? SLI (i use nvidia) in old games work fine with new drivers. I dont think that possible problems worse vs todays useless second gpu and negative scaling. But if SLI can boost madvr performance it will be great.
edit: I read some posts about multi-gpu here, but i don't understand, madshi don't want introduce it or it just impossible.

Hi guys. I have a challenge for you. You must download them and compare them in fullscreen and try to identify which Option goes with the right settings. After some time I will be posting the results.

This is the link: http://imgur.com/a/zmRYh

Movie Resolution: 720x480
Output Resolution: 1920x1080

In both options I just doubled resolution once and only in Luma, so downscaling algo is not relevant. So this test is basically to see if you are able to see differences after doubling between Jinc AR and Bicubic 60 AR.

One of the options is with 0.91.1. Settings:
Remove Banding: Medium/High
Chroma: NGU High
Luma Doubling: NGU High
Image Upscaling: Jinc AR
Downscaling: Not relevant.
Add grain and Soften Edges at 1

The other is with 0.91.3 version. Settings:
Remove Banding: Medium/High
Chroma: NGU Very High
Luma Doubling: NGU Very High (all auto)
Downscaling: Not relevant.
Add grain and Soften Edges at 1

What's this option? I've never seen it mentioned before.

Are you trying to say option 2 is jinc?
though that aliasing on the hat, option 2 looks better to me.

I tried with mpc and evr and it doesn't happen but I think that's because the PC just doesn't go to sleep when using evr.

With zoom player and MadVR I disabled the screen saver and power saving prevention and it doesn't sleep.

So why is mpc hc sleeping with paused playback with madVR and not with evr? Why does it bsod even if it does?

I won't tell you know. As I said I will post the results later. Just remember what options you pick.

Looks like the image in Option 1 (u2xyyDQ.png) is the one scaled with Jinc after NGU doubling. I believe though this kind of challenge would be more fair for movie content and not anime content.

Ok so I've jumped onto the latest madvr with this new NGU scaler (which is excellent), but I must have missed something about the change of all the settings. Where did image doubling go? I understand that the settings dialogues have been changed but I can't find any info from madshi in his latest updates in this thread.

My point is, I find the new settings kind of confusing, that's all. Especially with regards to the image doubling.

This weekend I will be posting the results, and I will upload the same challenge but with a movie instead of anime, the next challenge will last one Week, from one weekend to another.

Doubling and upscaling have merged into one. So in upscaling if you choose NGU or NNEDI3 it's doubling.

Agreed, it's a bit more focused/sharp.

Multi-GPU is a complicated mess and everyone is giving up on it for a reason - game devs and AMD/nvidia are all dropping the ball. Only DX12 could save it but that requires extra work (and training) for the game/app developers. I think only ONE game has dx12 multi GPU support as of right now (the last Deus EX IIRC? and that's not a really well optimized game to begin with).

Just look at how few recent releases support multi-GPU and how bad it is most of the time when they actually do. Poor scaling, bugs, (micro)stuttering etc...

This is even more ridiculous than asking to support VRR for video playback IMO.

I can vouch for that card as it´s the same I have in my 4K setup. It comes with an excellent cooler (average temp 65C) and high frequencies out of the box (typically 2050-2100 Mhz).

Having said that:

- All GTX 1080 models perform more or less the same, with a 100-150 Mhz max variance depending on the quality of the cooler (Pascal is pretty temp sensitive). If you´re not also gaming, just buy the cheapest version you can find. Games @ 4K will stress the card much further than madvr.

- A 1060, 1070 or any other card will work as well in 4K, they will be just somewhat slower in rendering time. It all depends on how important is to you to crank up the quality settings in madvr. I had a 980ti previously (= 1070) in the same 4K setup and run without problems. I wouldn´t upgrade only for madvr. I would do it if you´re going to game in 4K as well.

- If money is not a factor, wait until 1Q'17 and buy instead a 1080Ti, which will be around 25-30% faster than the 1080. Expected to be a 850-900$ card, though.

If you choose to use NGU for luma doubling (and you will use it, because it is excellent), you won't be able to select the algorithms that you desire for chroma upscaling and luma upscaling/downscaling anymore, to use after the luma doubling.

For instance, NGU can't be used to upscale 720p to UHD with my config anymore, because of the rendering times of the forced algorithms to have approximately the same quality. But you can use the v0.91.1 version to pick the algorithms that you want to fine-tune the image quality vs rendering times for your configuration.

I have a perfect result with those with my little 970 GTX :

chroma upscaling : super-xbr - sharpness: 150 (only NNEDI3 and NGU give better results, but rendering times are awful)
image downscaling : Catmull-Rom (if you want soft) or Lanczos 3 (if you want sharp) [both AR + LL], but I prefer sharp
image doubling : double luma resolution - 2x supersampling - NGU, medium quality
image upscaling : Lanczos 3 AR (sharper than Jinc, and very good to use after luma doubling to upscale anything < FHD to UHD)
upscaling refinement : add grain 3-4 (new refinement, still testing which is best, 4 for now)
artifact removal : reduce banding artifacts (high/high) + reduce ringing artifacts only (reduce dark halos remove too many details)
dithering : Ordered Dithering + use colored noise + change dither for every frame (good rendering times and almost identical to Error Diffusion)

I am also noticing far faster rendering on Dx9 compared to dx11--it's the difference between not being able to run NGU high at all and running NGU high comfortably.

Edit: Disregard that. After switching back and forth a couple times, they're the same (faster) speed now. No idea why.

Is there any reason not to use dx9, given that it seems more efficient? I'm guessing it may be faster on older GPU architectures.

I'm using NGU in conjunction with "reduce ringing artifacts". I definitely notice less source haloing and haven't really found enough ugly interactions between the two.

I'm also not a fan of bicubic for downscaling from NGU. Jinc is better

Jinc was not available for downscaling in previous builds as well.

For one, 10 bit is only available on D3D11 fullscreen exclusive. I don't know if it makes a huge difference, but IIRC it's supposed to help prevent banding.
