Update 2 IPR Slow ?

[muoto]

Hello,
i noticed that using IPR uses around 30% of CPU usage, and VFB around 90-95% of CPU usage...
something special to do to get full speed in IPR ?

Thanks

edit : max2020

Do you mean you get different performance between Viewport IPR and IPR in the VFB?

[muoto]

yes exactly, in IPR 30% usage of the cpu(s), and VFB is around full CPU usage

Can you send me the scene and make a video of what exactly are you doing?

I tried on a different workstation with simple simple teapot scene, simple hdri, in the begining the viewport ipr works fine, same speed as vfb, but then after a while turning and playing around, stopping and restarting the viewport ipr, I got the same speed slowdown. Very noticeable in the viewport display, and Cpu usage confirms the slowdown

Used cpu next update 2
