Chaos Corona for 3ds Max > [Max] Daily Builds

Corona 13 daily builds IR/viewport slowdown

(1/9) > >>

Majeranek:
Hmm.. am I the only one that noticed that with latest Corona build the interactive is really slugish? When I have material editor opened it's even worse. I don't know what's wrong with that but IMO every new version of corona the interactive is becoming slower.

The scene isn't complicated. It's just single object with bunch of lights.

Could you share an example recording showing the issue and a comparison with Corona 12 HF1?
I am asking because we are investigating some performance issues, but before I share anything I would first like to see what exact kind of "sluggishness" you are getting.

Majeranek:
Oh, I reverted everything back to 12 HF1. Everything is fine now. It was like few ms lag on everything, orbiting, moving mouse, changing values.

Aram Avetisyan:
Please, send the scene (or better the scene with the recording), so we can have a look at it.

If it is not found and resolved, it will most probably stay there and become an inconvenience later on.

If you are getting this kind of viewport lag/stutter for example when panning or rotating, it is most likely a 3ds Max 2025 issue. It happens with any renderer, even when Corona and V-Ray are uninstalled. I was also unable to reproduce it in 3ds Max 2024. This is already reported to Autodesk.

If you are getting something else, please do let us know. As Aram said, a scene and a video demonstrating the issue would be perfect.
