I've been trying to run Luxmark 3.1 on the iMac 2020 with Radeon Pro 5700XT. While it can do the default scene successfully, the two other scenes Neumann and Hotel hangs the entire machine. On Big Sur it crashes, but on Catalina the entire machine reboots.
The default sphere scene gives a GPU OpenCL benchmark of about 22000.
Has anyone run the other two scenes successfully? I'm not sure if this is a hardware issue. I even use Macs fan control to force the fan to run at full speed, but it still crashes.
Geekbench's OpenCL benchmark works fine, but I think it's not as demanding as Luxmark.
