Use iGPU for Video Acceleration

[RedXon]

Hy guys

 

As you all know, the AMD cards are pretty bad with Multi Monitoring and Video Acceleration considering temperature and power usage.

While I could sort out the multi monitor problem, by connecting my second and third screen to the iGPU connectors on the motherboard, I have not found a way yet, to let the iGPU do the acceleration work (on youtube, for example).

 

The problem is, that my card, a R9 290 Tri-X btw, has to run the memory clock at full speed when I'm watching a video. This of course uses a lot of power and produces a lot of heat, which means, that the fans turn on (two of which turn off, when the temps are low enough). What this means is, I use more power, and it is louder. In fact, the graphics card is not hearable in idle, but I hear it when this happens.

 

Is there a way, to let the Intel iGPU do the work like for example video acceleration and stuff, other than 3D Gaming? That would be a great option.

 

Thanks

You could run the monitor you're watching the video on off the iGPU, and game on the other.

Or not worry so much lol, that's my vote.

Thanks, but that does not work. It does not matter, on which monitor I have the window open, the dGPU accelerates everything.

I can even game on the secondary (or third) screen and still the game gets rendered by the dGPU.

 

Yes, not to worry would be an option, but I'd prefer it if I could save power and reduce the temperature and most important noise of my PC.

Run one monitor off the iGPU and the other off the GPU is what I'm saying

Oh, yeah that's what I said in my intro post, I'm already doing that. Like I said, main Monitor goes via DisplayPort to the 290, the other two via HDMI to the iGPU.

It helps with the memClock on desktop for sure, but not when watching video, regardless on which monitor the player (or browser or whatever) is open. And since watching videos consumes many hours of my daytime, this is an issue for me.

 

All I was asking is, if there is a setting in Windows (or Chrome or whatever or 3rd party app) to do such things on the iGPU.

If the monitor you're using to watch videos is not hooked up to the GPU but the iGPU, then the GPU should not be effected. If it is that's really efin strange

[RedXon]

Oh okay, I was not aware of that.

 

So okay, I closed everything and restarted the computer. I played back the video on the third monitor and boom:

I noticed something very strange, I don't think that it's supposed to be this way: have a look.

The think with the constant spikes in GPU1 Memory Clock is in idle. The constant phase is the video playback on Monitor 3 (on the iGPU). It seems that the longer I stay in Idle, the less the clock tends to go up. I don't think it is supposed to be this way...

 

By the way, if I don't play a video at all the clock stays down and the temperature also stay under 50 degrees.
