Hi Paride,
it seems that itoo forest and other scatter tools eat up too much vram.
I have 180000 stones to scatter and that eats up around 100 MB of vram. If i double it it will be 200mb
It seems that instances eat too much vram. Dont they just use vram for position, rotation and scale only?

Thanks

Hi coilbook,
I had some test, actually seems to be a little too much.
I will send my report to developers.

Thanks. Please tell them to look into vram usage in empty scenes. I just don't get why with just 16 parallel samples I am using 1 GB of vram in empty scene. 32 is almsot 2 GB Plus windows 10 wastes 2.5 gb. So out of 11 gb of vram I am only left with 7gb. This is just not right
