Thank you for noticing . There is nothing wrong with your setup or configuration, and there is a performance regression. And guessed right that it’s caused by refactoring: the new NVRHI backend works through UE RHI and it turns out that way is much more expensive on the CPU side. I didn’t anticipate that, so didn’t benchmark that change. Sorry about that.

I’ll fix in the next few days.

Done - please try the latest official version. I reverted back to the old, less clean, backend, which happens to be much faster.
version also fixes some flickering/corruption issues with dynamic geometry such as particles.
