Slow Viewport performance in IPR
« on: August 30, 2019, 04:01:44 PM »
Hello,

Recently I updated to v-ray 4.2.1 adn forest 6.2.2. I thought that IPR with forest will be very responsive in viewport.
I upload a short scene with few objects in forest. In this scene if I turn off forest i have above 100FPS, but when turned on it's below 10FPS and can edit anything.
Can you look at it?

Max 2014, Win 10.

Best Regards,
Wojciech

Hi

You can disable Surface auto update. That seems to help a lot:

Ok, but if I set the density to 20 it's almost imposibble to change something in scene. There are big lags.
I thought it should be smooth as on the video from you. https://www.youtube.com/watch?v=b1QJkzU9O6E
