Previews still not working, i will keep on reporting it, over and over and over again

Can someone tell me why it takes almost as long for a preview to start than it takes to actually render some vidoes in Iris, this is really really really really really getting annoying now>
Back before Studio an Iris preview would start in about 10 seconds or so on a good day, I can’t remember the last time i pressed preview and it actually did something. GPU does nothing, CPU does nothing, ffmpeg just stalls and it sits there for 5+ minutes before the first preview will start and subsequent previews still take forever.

So far your only resolution has been to go back to a version released in April, however I paid for 12 months of updates but by the time you fix this my subscription will have expired, your programmers may be ‘working on it’ but please tell them to do better.
This is not just ridiculous, it is INSULTING how little regard you have for your customers.

Can you pull the logs for these preview attempts and send in for review?

If I remember correctly the previous issue we were looking into was SL models and that was being worked on by the devs and their recommendation was to roll back for that situation to use the model as it was working in a previous release.

I am not currently aware of a known issue with the Iris model and running previews, but want to look into this and see what is going on for the devs to investigate further.
