Octane 3 Performance Issue

[Henrik_B]

Hi there,

i just saw that JimStar released a stable octane 3 Version for blender and installed Version 3.04.3 to test it. What i noticed is, that the Performance is much slower that in 2.25. I got 2x TitanX and in 2.25 i have about 5.00 Ms/sec... in 3.04.4, same Scene, same Settings etc., i have only 1.72 Ms/sec... and everything feels much slower.

Is there any know issue about that ?

Regards, Henrik

1. Are you sure you have latest NVidia drivers installed?
2. Have you tried to export the same scene and compare its speed in standalone 2.25 and 3.04.3?
3. Could you share the scene where you see this difference?

Thanks for your reply JimStar and sorry for the late answer. I noticed that the Alpha Shadow option is a real performance killer..... i think that was the problem. So everyone who doesnt need correct shadows for alpha-mapped geometry or specular materials should turn that off!

Anyways. Thanks again !
