Using GPU 1 for Youtube while playing games on GPU 0

iBabySlapper

Hi Guys

 

My full PC specs are in my sig, but I have a R9 390 and a GTX 950 (which I bought for encoding HEVC).

 

Ofc I have the my gaming monitor (the Samsung) connected to the 390, and my other two monitors connected to the 950.

Is it possible to offload browser video playback to the 950 while I play games on the R9 390? As of now, when I play a video in my browser, it's the 390 that does the decodes even though the video is playing on a monitor connected to the 950. My browser is the latest version of Firefox.

 

This is only an issue with Youtube/Firefox, as running something like media player classic on the secondary screens will use the 950 as it should.

 

Thanks

The r390 will have no issue decoding the video while playing a game

I believe the video decode is a separate block from other parts of the GPU so it doesn't really impact performance.

 

The other solution to force this is the route I went. GPU2 is in a separate physical system to GPU1. I can still control both systems with on keyboard/mouse using Mouse Without Borders. Of course, this has different benefits and other usability tradeoffs e.g. can't move stuff to 2nd monitor.
