Very slow viewport with smoke and particles
The video is attached

Hey, can you show me how the Preview rollout looks like and the cache info from the Simulation rollout?

Here is the scene with phoenix grid and a picture with roll out

Hey,

Thanks a lot for the scene. Looks like a bug and it happens when you have quite a lot of particle systems in your cache. In your case you have more than a 100. If you disable the Particle preview the performance should be a lot better.
Will let you know when we have something more on that.

Cheers,
