A good question. GPU memory usage when upscaling / downscaling V5 (1920x1080p60) / V6 (4096x2160p60) to 3840x2160 with HD 7770 GDDR5 1GB + madVR Level 3:



- V5: 540MB / 380MB
- V6: 510MB / 200MB

So 1GB is enough.

Quick question,

by using these programs to tweak your HTPC are you guys getting better picture quality than what an Oppo is capable of?

I ask because I would really like to build a HTPC capable of gaming and bluray playback when my PS3 finally dies(I suspect it will be soon) but I would like something with great picture and sound. I know I can bitstream the audio to the receiver for decoding of pretty much any format but I knew that the codecs for the video were usually limited to Oppo and other stand alone products.

I was also considering trying to get ahold of a Color Box with the Cube calibration to enhance the colors even more out of the HTPC for the best playback possible.

so if somebody was to give you a HD 6570/6670 for free would you still stick with the GT430?

and is it worth my while to try both cards to see if there is any difference?

I have a blu ray burner and plan to rip blu-rays now and then so please keep this in mind.

This is a good question:

I thought about this myself and I was leaning towards the 2GB.

My thinking was that 1GB is enough, but 2GB is still better and the difference is only $10 or $20 usually. How I see it is that if you choose the appropriate card, it should work fine with only 1GB but 2GB is still better. If you are at a point where 2GB would work and 1GB would not you are cutting it too close and should probably step up a level on the card. If you are choosing a card like a 7790 or any 8xxx card you should be ok with either version.

Thanks for the data and your opinions.

This was my thought as well. I just picked up a 2GB 7790 for my new build before reading through this thread. I figured it wouldn't hurt for a couple bucks more. It's nice to see that it will do what I need it to do for some time.

No prob biggrin.gif I am about to pull the trigger on the same card. What brand did you get ? Is it quiet ?
post #97 of 613
I got this one. I only had it installed briefly and then had to pull it out. When it was installed, I didn't think it was working because I literally could not hear any difference in the machine. I had to feel for the fans blowing to know that it was on. I think I am going to be very pleased with it if I can ever get the computer stabilized.

Stabilized ???

My components don't seem to be playing nice with each other and I don't have a clue what I'm doing so that doesn't help either.

Start a thread ill help you troubleshoot.

Unfortunately I have a vast amount if experience with this area.

What's the issues ?
post #101 of 613
Anyone with the Radeon 7770, how is the heat with the card?

My current Nvidia runs really hot.

Also anyone using DVI to HDMI output with audio? I used this with my current Nvidia to get around handshake issues.

Thanks

Did you end up with the HD7790? I was disappointed with mine and pulled it in favor of the GT 650Ti Boost SC from EVGA... Yeah power consumption and heat are a bit more but the card is significantly faster. Virtually all the performance problems I had been seeing in JRiver MC with madVR and cable TV went away. I still have the 7790 and will find a home for it here, perhaps in the box I am typing in right now. Not a bad card but I went through the 7770 to the 7790 and the darned thing would not stop dropping frames with the Ceton in JRiver and madVR till I got to that performance level. One thing about he 7790 was it was on its own driver fork for awhile. I wonder if they ever got it supported with the standard releases?
post #103 of 613
7790 was released in March. 13.4 ('13 April) driver supports 7790 but with some bugs, hence AMD released an updated driver for 7790 (I still noticed obvious bugs, however). The upcoming 13.7 (?) driver will support all 5xxx - 8xxx GPUs.

renethx: quick question on madvr levels

Is there a setting in madvr to select the level itself, or do you set the settings separately; e.g. madVR Level 2, you set BiCubic75 and Lanczos3?

Could you post screenshots for what you set for madvr level 4. I dont see level options...maybe using an older version.
post #105 of 613
The notion of levels is not official but just mine. Instead of describing a set of three scaling algorithms like "chroma upscaling: Bicubic 75, image upscaling: Lanczos 3, image downscaling: Catmull-Rom", I just call it "Level 2". It's just an abbreviation or definition for the sake of convenience. Nothing new is introduced.

Level 2 = (Bicubic 75, Lanczos 3, Catmull-Rom)
Level 3 = (Bicubic 75+AR, Lanczos 3+AR, Catmull-Rom+AR)
etc.

Is there a good place to look to both obtain the newest MadVR and set it up for someone who has never touched it or read about it before this thread?

Take a look at MINDBOMB's Advanced MPC-HC Guide. The link and basic settings is in the first couple of posts.

MadVR does not require MPC-HC, does it? I use WMC for my playback. Also, it says there is not a 64bit version, is that still the case?
post #110 of 613
It can be forced to load in WMC but I believe that you need to get into registry hacks and such. MPC-HC is a better player anyhow because it is so easily configurable. madVR does not have 64bit and I don't know if it ever will but it runs just fine at 32 bit.

If you are not using MB for library management you can use Mikinho's Open With WMC add in to force WMC to use MPC-HC as the player for certain file types.

This won't work for TV playback with tuners AFAIK.
post #111 of 613
Ah, ok, TYVM!
post #112 of 613
renethx: Thanks for this great information. My question might sound really silly since I am using SNB i3 2100 with HD2000 onboard graphics. Is there really a hope for me to get a good setting for madVR? I primarily use MPC-HC + madVR for DVD playback on 1080p projector.

DXVA2 is always the best for every Intel iGPU. Intel iGPU is optimized for running Intel driver's scaling algorithm on ASICs instead of running madVR's own algorithms on EUs (simply because there are not enough EUs for this purpose). You may need a faster memory to play back some video contents (i.e. not film) without dropped frames, however. If you see dropped frames, just stay with EVR (not EVR Custom Presenter), there is no big difference in PQ between EVR DXVA2 and madVR DXVA2 (because of the same Intel driver's algorithm).

Can you direct me how to set this up? I have MPC-HC installed, but don't know what to do after that. (I have experience of using LAV filters and MadVR using the guide)
Thanks
post #115 of 613
If you select EVR (non Custom Presenter) as the video renderer, then DXVA2 is almost always used automatically. If you select madVR, then go to madVR settings, then choose DXVA2 for image up/downscaling in scaling algorithms (and Bicubic 75 for chroma upscaling, that is used when no image scalng is applied).

Just got my Radeon HD 7770 in today...can't wait to test it out.

Saphire's "Vapor-X" edition...figured I'd spend a bit more on better cooling since my GT460 is burning up my HTPC.

You will love it. That is what I run and it added no more noise to the system and can run all the great high mad-vr levels smile.gif

I've seen screen shots, and read explanations, but without the hardware, it is hard to self-demo.
Are there directly comparable downloadable video examples out there of SD movies processed with different algorithms?
Like...
Vid 1 = basic intel decoding
Vid 2 = MadV "lvl 2"
Vid 3 = MadVR "lvl 5"
Vid 4 = MadVR 5 + SVP etc
post #119 of 613
How's that going to work? It will only be as good as the monitor you are using and the player you are playing it on if it is screen capture and worse yet if it is shot with a cell phone or video camera aimed at the HDTV. There really is no way to do this except by experimenting with it yourself on your own hardware and especially with your own monitor in the room that you will be using.
post #120 of 613
The thought was this. MadVR doesn;t do much for SHD material, and it is for upscalling SD material. Our computers can play SHD just fine. So...take SD material, and use different upscale algorithms to generate SHD files where all the processing to upscale has been done.
