Hi
I have an iMac Pro 2017 and just upgraded to Big Sur and running latest version of R23. Radeon Pro Vega 64 16 GB.
Using multi instance mode (as points or even off) is extremely slow and jerky to navigate viewport (clone numbers ~30-40,000 simple spheres. Previously in high Sierra using R22-R23 had no difficulty navigating the scene.
Is this a known issue? Is there a fix?
Thanks
Cheers
Chris
