IZOTOPE RX 6 CLOSING PLUGIN WINDOWS LAG ARCHIVE
More precisely : I select the long archive clip in the Media Storage (not imported in the Media Pool yet), right-clic on it > "Scene Cut Detection.", and process. On import, we use the Scene Cut Detection to have the whole archive clip in a timeline with cuts. So there's quite a few long video clips (more than two hours), mostly in PAL DV (so not very hard to process). Here's context about the project and the workflow : it is a documentary feature based on personal archives, usually 8mm scanned to video. I also disabled the thumbnails and waveforms display in the timelines. The database (postgreSQL, not Disk) resides locally on the system's SSD (also not the culprit, according to the very low Disk usage in Activity Monitor when opening, saving or just clicking on another timeline). Other than that, this Mac is equipped with 64 GB of RAM (clearly not full, as Resolve currently uses no more than 4 GB of RAM) and a Nvidia GeForce GTX 1080 Ti with 12 GB of VRAM (also not the bottleneck according to Activity Monitor, besides the sources are plain PAL DV MOV, and the timelines are set to HD 1080 25fps).
Using the latest () version of DaVinci Resolve Studio, opening a timeline (or switching to another timeline in the same project) containing a lot of cuts (around 2000 - 2500 cuts, according to the Edit Index) results in DaVinci Resolve hanging (macOS' spinning beachball) for several seconds (up to 12 seconds), while the processor usage climbs to 100% on one core only, regardless of the 24 virtual cores available (2 processors, each with 6 "real" cores at 2,66 Ghz) on this mid-2010 MacPro.
