Thank you for the update.
Does Task Manager now show that all ONYX processes and DyLOS, are all using the same GPU?
If all processes are now using the same GPU, but the issue is persisting, please try updating to our latest ONYX public beta. ONYX 4.31.1300 can be downloaded from the link below…
Onyx Beta 4.31.1300 (RC3) - ONYX / Onyx Betatest - Obsidian Control Systems
Installation instructions can be found here…

Once running this version, please let us know how you get on.
