Hey guys,
So I just got the new 15inch retina MBP with the R9 graphics card and experienced a really weird problem.
When I was testing things out with a single HDMI output and DXV 2 content I realised I was getting only 30-40 FPS, even with single layer. Then I remembered that "Use displays as separate spaces" was on by default. So I disabled this and then everything was fine. I was getting a stable 60fps even with multiple clips and layers.
Yesterday, at a show I connected two displays to my machine, 1 HDMI and 1 DVI. The moment I hit advanced output and Arena detected that I was using 2 displays, the frame rate just dropped to 30. Even with no content playing. I even added multiple clips and layers of content but it just stayed at 30fps.
The moment I would disable the second screen from advanced output. It would shoot up to 60fps again. I tried disabling and enabling both screens thinking it was an issue with maybe the source i.e HDMI or DVI.
Then I tried turning ON displays have separate spaces, and everything was fine. I was getting a steady 60fps even with connecting 3 displays i.e 2 DVI and 1 HDMI.
I added multiple layers of DXV content and it stayed at 60FPS.
Any idea what could be the problem here?
I thought displays have separate spaces had to be turned of for better performance.
Thanks
