Framebuffer intreraction lags

[Mr.Hoo]

Hi,

this one is a little bit tricky to reproduce.
I found that if I render bigger resolutions, say 4K up, the interaction in the framebuffer becomes very laggy:
e.g. zooming in/out, the buckets don't update, switching AOVs, etc.
sometimes the framebuffer doesn't updates buckets for minutes...

Is this a known issue or does somebody else have it? Or is it only me?

In Maya for example this doesn't happen at all.

cheers
Dominik

Hi Mr.Hoo , what is your setup, OS, Houdini and V-Ray versions. I can't reproduce it on my side, even when I am using a remote desktop.

I would like to kinda make some screen captures, but at the moment the projects are confidential. I hope i'll find time to setup something to reproduce the issue

Is this happens only on CPU or GPU, or both ? If you have a non confidential scene which you could share will be perfect, even simple one.

[Mr.Hoo]

I just tried cpu.
Even the poise pointer gets a lag.

I will see what I can do, perhaps i just scatter some pigheads in the scene

Is this problems appear in IPR mode? I realised that IPR in Houdini is rendered in the same resolution like production render. This is suboptimal to say the least... In 3ds Max IPR resoulution is dependant on IPR window size...

Mnietek2707 , unfortunately this option is available only for 3dsmax and Modo.
