Hi savage309 and Peter.Chaushev ,
I have a complex train interior and if I start a first rendering than the GPU usage at GPU1 is approx. 6700MB and at GPU2 5900MB (no NVlink enabled, GPU bucket mode). This values are quite good, I can render my scene without problems. But after the rendering is finished the VRAM doesn't goes back to the low values before rendering. OK, maybe some data is cached, but every new rendering cause an increase of the VRAM usage and after a few renderings the limit is reached and some times Rhino crashs.
(Also interesting at the VRAM usage graph - there is an ugly peak at the end of one rendering (see screenshot GPU-Z GPU1). This I haven't seen at other renderings (next rendering at the graph is without peak). General if the GPU pass is started (after the LC) than the VRAM usage increase to a max value and doesn't increase anymore until the end. Maybe this kind of peak can be avoided.)
My question is - could it be that we have a kind of memory leak? Could the VRAM usage kept constant so that I could render my scene several times without to restart Rhino? I hope a solution could be found, so that a 11GB card could be used without problems over the time.
