For the past 2+ years I have been using my 2018 Mac Mini i7 (64GB Ram) with an eGPU (AMD Rx580 in Razer Core X TB enclosure) with great success, but recently the GPU has started overheating and without intervention it will crash the Mac.
If I leave LR Classic to build 1:1 previews for a folder, I will come back to a crashed Mac and when restarted, only 25% or so of the previews are built. This can go on repeatedly.
I've looked at crash reports and other contributing devices and software but it seems Lightroom Classic is the only common factor.
I use iStat Menus to monitor the Mac and a consistent and revealing behaviour is that when I use Lightroom for a GPU intensive task the GPU memory builds up but never drops down even when there is no activity at all. Quitting LR and re-opening purges the GPU memory. I have attached a file below where you see the high usage, which only drops when restarted (at the top of the cliff).
I use two monitors, a 2K BenQ SW270C connected to the GPU by DP and a 1K Eizo CG241W connected to the GPU by HDMI.
My LR Performance settings are maxed to Use GPU for Export and the system info in LR confirms the GPU is supported by default.
This behaviour was intermittent over the last 2 years and has been increasing over the last 6 months to the point now that it is constant.
I have updated all software and drivers consistently, but am holding off updating to Ventura on this Mac until I'm sure it is stable for pro workflow.
The Mac's crash reports and other logs haven't given me any clues but I am not that savvy with the finer details of that level of IT, so hardly surprising.
However, if someone on the forum does have that deeper understanding and has some ideas as to how I can diagnose and/or fix this issue then I would really appreciate it.
