Wanted to add more info to my findings to help the developers. Looks like 4K,5K and 6K resolutions play nicely, but 8K resolutions is where the playback struggles a bit. - Sometimes during playback with 8K footage the dropped frame indicator will show green, even though its dropping frames during playback. Decribed below I have found this to be the case with 14.2 and 14.3 (beta) versions (I THINK THIS IS THE ROOT CAUSE) -If the source monitor and program monitor both have a clip previewed, the timeline struggles to play 8K footage, but if the source monitor is displaying anything other than a clip from the media bin, the timeline plays back perfectly. Its as if the source monitor is causing the program monitor to play choppy. Example: if you select the "effects" tab in the source monitor the clip in the timeline that was struggling, no longer struggles to play, but as soon as you show the clip again in the source monitor, the clip in the program monitor struggles again. Again this is only happening with RED 8K resolution footage.
