Did some GPU tests today. My main monitor is a 65" 4k TV running HDMI 2.0 @ 60hz, at 2560x1440 HiDPI. I noticed a little screen redraw improvement going from 2013 MacPro to 2018 Mini with BlackMagic RX580 eGPU.

I did 3 tests while ProTools was in playback with only the mix window showing:

- 2560x1440 HiDPI
- 1920x900 low res
- 2560x1440 standard

Nothing was present on my other two monitors.

You can see on the GPU window from Activity Monitor that the RX580 is at 100% usage at 2560x1440 HiDPI, and goes down from there. I tried a quick test on Logic Pro, and couldn't get it to 100%.

So - do I need a faster eGPU (Vega 56 or 64) or is ProTools just not ready for HiDPI yet?
