CUDA rendering long startup times.

[Khazmadu]

I have a scene with 300MB geometry and 150MB textures.
Then I render it with the CPU it takes 2-3sec till the rendering starts.

But then I switch the Render Engine to CUDA it takes much longer (17-18sec)

I created vray Proxies for the Geometries but that didn't change anything

"Cache Plugin Geometry between renders" doesn't seem to work with CUDA rendering.

Is this just what I can expect or is there something wrong with my Settings or Setup?

System:
Windows 7 64Bit
Vray 3.40.02 for Maya 2016.5 SP6
Nvidia GTX970

Have you tried V-Ray 3.52?

Not personally but I was told the problem is the same with vray 3.6 and a GTX1080.

i noticed that too... very strange...

It usually is expected to start somewhat slower. Depending on the case though, it might be a bug as well.

It's just that it seems to start much faster in 3ds Max.

It's just that it seems to start much faster in 3ds Max.

Is that with the same V-Ray service packs? If so, we will try to reproduce that here.
