Hit Film Express 17 (2021.2) running super slow

Sehremis Posts: 7 Just Starting Out*

So, I just upgraded from Hit Film Express 16 (2021.1) to Hit Film Express 17 (2021.2) , and the performance dropped to levels that made it impossible for me to get any work done. The program would regularly freeze for multiple seconds, and I'd experience HEAVY lag when dragging objects around.

I then downgraded back to Hit Film Express 16 (2021.1), and the performance was up to normal levels again.

Is anyone else experiencing this? And what's up with this?
