VRay RT GPU (Cuda)

[MildMustard]

I am really trying to start using RT-GPU as much as possible so I will add to this thread of issues I find.

1) The first issue I am finding is while rendering with GPU of an interior scene, my system RAM usage goes through the roof. About 27Gb while rendering with RT-GPU, CPU uses 9Gb. I thought rendering with GPU wouldn't use system RAM?

2) Also rendering with a surface particle generator attached to a replicator for a leafy hedge in this interior just bombs RT-GPU, while when I painstakingly Freeze the Replicator and merge all the leaves into 1 object then it works really fast again. (some days like today I wish modo performed better with may items in the items list... selecting and merging takes forever...)

3) Gradient texture doesn't work on Texture U And Texture V. Or am I doing it wrong? If it doesn't work right now, would it be possible to added it?

Can you send me these two scenes, so I can check what's causing the large RAM usage and the slow-down with the Replicator ?
