Hmm I observed ram usage increase from 28-30gigs of ram up to 42gigs on that scene i'm working on - not a big deal but seems to be on 15%++ side of things yet speed increase is surely worth it )) Anyway that scene of mine uses some proxies, some forestpack objects and some displacement - well the usual wip mess of a scene so it's hard to tell what can be chewing that additional ram + one strange thing I observed while doing some 4k preview rendering of it - scene started to render using some amount of ram then it did displacement + secondary gi and went up to 42gigs (well more or less the usual thing) then it rendered to around 4 passes (around 10 min or something) using those 42gig and then, suddenly, while rendering 5th pass it jumped down to 36gigs - never seen Corona behave like this - maybe it's something wrong on my end and that initial bigger than +15% ram consumption increase difference I'm observing is not normal after all.
I've been seeing some very odd Ram usage too. Can't figure out if it's Max or Corona. Running the second most recent daily build as of today. My scene sometimes renders at 8gb and sometimes 20gb. Seems like it's random. Even tried merging into a new scene and no luck. Just have to keep re opening and re rendering till Ram usage drops. Pretty simple interior archviz scene with forest pack and no displacement to speak of.
On another note, can't wait to try the newest build and compare speedup!
So, weird RAM usage is still there in the latest build. What I notice is that after rendering for a few minutes it drops from 20gb to 6gb! Super weird. No distributed rendering, just local. Only one render element (Object ID). Then, if I stop the render and then hit render again, the ram usage stays low at like 6gb. Any thoughts? I'll have to test with DR and see if nodes stay high or go low...
New speed increase is super nice by the way! Fewer fireflies, sharper edges, less noise, etc. No more 'passes' but that's kind of an arbitrary number anyway.
