Rhino 8 WIP viewport much slower than Rhino 7 and often freezes

Tested on my work laptop:
Rhino 8 SR0 2023-8-8 (Rhino WIP, 8.0.23220.12305) = 6.53 seconds. (15.31 FPS)
Rhino 8 SR0 2023-8-15 (Rhino WIP, 8.0.23227.12305) = 5.38 seconds. (18.60 FPS)
Rhino 8 SR0 2023-8-22 (Rhino WIP, 8.0.23234.12305) = 3.23 seconds. (30.91 FPS)

Good Stuff!
