Hi, i will upload a scene too, parsing times have increase twice the time per frame and using twice the ram calculating displacement, i was able to render a video on version 7 with 128gigs of ram, now the same exact file (client ask for a roof color change) and it take twice the time and ram, corona 7 time was 6 minutes per frame, corona 8 11:38 sec per frame, il let you know when I'm able to upload, still on deadline (was looking for some solutions but cant find one), ah almost forgot, this scene (ande several from the same project) no crash almost every 10 frames per machine, its very annoying, didn't happened on v7, i sent some log files by mail from this crashes, I thought it was related with max 2023 but it doesn't, also huge issues with 2023 and backburner, thanks for the effort guys.
