next GPU ram usage?

[super gnu]

i understand that the gpu code has been rewritten, but it seems the changes have reduced the scene complexity my gpus can handle. i have my current scene rendering fine (just!) in 3.6.. swapping to the Next trial version (excited to see the speedup!) it refuses to render with out-of-memory messages for the gpus.

also, if it fails once, if i hit render again, it tells me there are no cuda devices present, and i must restart max.

What it should do is to use the *free* memory left after a scene is loaded for additional optimizations.
In most of the cases it does that. We have one more user with such reports already, but we couldn’t reproduce his problem on our machines yet.

Can you send us your scene so we can try to reproduce the problem at our end? If we can, it will help us a lot to track the bug and fix it.

Best,
Blago.

yes i can send you a file. give me a little while to package up the scene.
