It's called SimHD, it has nothing to do with the feature discussed in this topic.

It is Arcsoft's GPGPU upscaling program. It works on NVIDIA too.

gotcha! sound like major bs....like that "UVD2 DVD upscaling" when they can't even progressively upsample chroma

Heh, I always wondered if some company would implement SR on GPU at some point (simply too slow in software and I gathered it might be doable in realtime with GPU).

Of course, the gotcha is, it won't (can't) work always and for all sources (at least not "perfectly"), as it requires proper temporal matching from the source already and that simply is not always possible.

When it works, the results seem quite good (beats simple bicubic/lanczos + sharpening, at least, when comparing single frames - hardly noticeable difference in motion).

Would be interesting to see some full screen shots at some point, though.

It's already done the first where MotionDSP (U.S Intelligence sponsored) with Ikena Reveal www.motiondsp.com the consumer version Carmel is soon going to be released Nvidia Exclusive
SR is not new the concept is already 20 years old tough it was hold back for a long time from public use (to much costs so Military and Intelligence use only) now the first commercial Consumer application i remember is a Russians SR implementation though MotionDSP's should be more advanced.

on the links that tetsuo gave, they don't talk about SR....I guess they'll do some PS sharpening through CUDA(a la All2HD in WinDVD9)

@CruNcher

Yeah, SR concept isn't anything new. I remember reading about it in the 80s already (wasn't called "SuperResolution" at the time - I believe that term was coined sometime during the 90s).

That image looks pretty impressive, almost no haloing except around the edges of the cake.
We will see what it looks like in real life.

Did you try using ffdshow with forced NV12 output (uncheck everything except NV12), that automatically activates other AVIVO processing, so it should work with this too.

Right now I'm using MPC - HC with DXVA accelleration. This works fine, but as soon as I activate de VMR9 mixer feature it starts behaving erraticly. Frames go "jumping" mostly, that is, they get mixed up often. I can enable the hardware acceleration features but not the VMR9 mixing, so I don't get the built in AVIVO image enhancing techniques for MPEG-2 & h264. Anybody else in this case?

Khagaroth, what are the (other) consequences of only using NV12 output?

What build of MPC-HC are you using? If you are using one of the latest builds, this is a bug in MPC-HC. You need to revert to 1137 or before.

Yes, I'm using one of the latest builds (1180). Is this by any chance getting fixed soon? Because I was kinda fond of the improvements made since build 1150.

Thank you for the tip! You were absolutely right! h.264 encodes get decoded perfectly right now. I don't seem to be able to get mpeg2/dvd streams working with AVIVO acceleration though? What course should I take regarding these types of streams?

The MPC MPEG-2 decoder is not DXVA accelerated. if you need/want DXVA with MPEG2 you need to use another decoder, like Cyberlink, Nvidia etc.
