Did some very rudimentary, eyeball results testing using a JP particle stress testing world if anyone cares. (wrld_708a3c63-9d97-4edb-9343-50e15a1ad156)
I tested desktop 3700x+ 5800x3D and VR 5800X3D.
GPU is a 1070 FYI, pretty weak hence why I aimed for a low VRAM/GPU intense world.

VRC in desktop seems to never go above your screen framerate, so the max I could go was 144FPS. I there's a way to unlock this lmk.
Desktop 3700X got around ~110FPS doing nothing, and desktop 5800X3D was maxing out at 144FPS.
Spamming the most intense particle gun (red) the 3700X dropped down to around 18-22FPS where it sat as the particle limit seemed to plateau due to despawning. 5800X3D hovered around a steady 60-65 FPS, with rare dips to mid 50's and spikes to low 70s.
(The FPS I'm referencing here is displayed by a sign in the world.)

VR no particles 5800X3D FPS was hovering between 90-110, but inspecting the frametimes of ~2.5ms for CPU and ~3.1 for GPU it's a GPU limited moment.
Spamming particles with VR 5800X3D the map fps hovered around 40-45 stable. CPU average frametime was around low 7.Xms, GPU around ~5.

Gives you an idea on the capability when dealing with particles. Sorry I did no 3700X VR test, I forgot, am lazy, and figured desktop was a better performance platform anyway given my hardware
