Dual RTX 3090 / RTX 3080 severe hit in performance

Hey Everyone,

managed to source a 3080 and a 3090 for my workstation and thought I'd give Arnold a try in Houdini. To my huge surprise, using both GPUs are not helping but rather slowing down rendering A LOT, I have to manually select a single GPU to have decent performance.

Tried Windows 10 and Ubuntu 20.04 with 5.4.1 demo, same issue, no love. Could anyone shine some light on what am I missing?

Thanks!

This might be fixed as of Arnold core 7.2.5.0. Let us know if you're still having issues.
