I've been using this setup (in my profile) for over a year, but at some point in time FCPX seems to have slowed done. What used to play smoothly now doesn't.

I'm wondering if it is hardware acceleration on the RX580 (or lack of)?

Using VideoProc it shows either the intel graphics card from the motherboard if that is turned on (but with the 580 as the main one in the bios), or nothing if it is turned off. Mac system status shows the RX580 eitherway. I am using the trial version of VideoProc by the way, I don't know if that affects anything.

I've spent a lot of time going through threads and trying lots of different things, and I know this has been discussed to death, but I just can't find the right settings for my setup and I'd be very grateful if someone could help.

Thanks
