Hard Crashes on 2019 Mac Pro

I’m running a Mac Pro (3.2 GHz 16 core Intel Xeon W; AMD Pro Vega II Duo 32 GB; 128 GB RAM, Mac OS 15.3.1). I run a LOT of stressful software on it: Satellite simulations in MacOS; Bootcamp for Windows 10; Parallels for Windows 11; Systems Took Kit under Windows 10, and such.

The ONLY (and I do mean the ONLY) application that completely locks up this Mac Pro is WoW. WoW locks it up to the extent that I have to do a hard reboot of the entire machine! That is completely power down and do a cold restart.

There does not seem to be a pattern (length of play, area of play, grouped/not grouped, in battle or not in battle, in a delve or not, etc.) Yet, the complete lock up requiring a cold restart of the machine happens all too often, sometimes multiple times in a couple hour playing session.

None of the other applications cause me to reboot this machine in any way, just WoW.

Suggestions?

I have a working theory that Blizz might be starting to get away from intel macs and only supporting M-Series macs.

M4 Mac mini or Studio would run WoW and MacOS stuff much better (although not Bootcamp/Parallels). Blizz did a really good job on the Apple Silicon version of WoW.

For Intel Mac the only thing I can think of would be basic stuff like scan and repair or reinstalling WoW.

I’m on a similar system and have never had any issues like this – rock solid on my 2019 Mac Pro. Running Sonoma, however.
