@Paradox55 Ah ok thanks. I had incorrectly assumed that the 970 supported 8 and 10 bit HEVC not just baseline. Good to know that even if I had a supported CPU I couldn’t use the gtx 970 for those formats.
I did some more digging as well. This thread suggests that dedicated gpus are only useful for playback directly on the device anyway if I’m reading it correctly. I will have to look into getting kaby rig going for just plex.
Until then I’ll just avoid playing h265 files on clients that don’t support the format natively. Is it possible to disable payback of specifically h265 files only when transcoding is required? Id like to make my server idiot proof for other users and It’s not great for my power bill when I’ve got 16 cores pinned at 100% usage all the time.
