Hi, @defaultysm9et72px63 Thanks for writing in and providing the screen recording.
I have a few questions and some suggestions.
Question:
What type of media are you editing with (what's the source), and what's the resolution?
Is this new behavior, or did the performance issues occur in previous versions?
Where is your media stored? Internal/External SSD or disk?
Things to try:
Reset preferences and plug-in cache
Hold down Shift+Alt while Rush is launching.
Clear your data cache
Launch Rush > Click on Edit > Preferences > Manage Cache > Click on Delete All cache files
Update GPU driver
Render your sequence
From within a project, go to the Sequence menu and select "Prepare for Playback."
Try to lower the quality of playback.
Under the monitor, click on the more options menu > Select, Preview Quality > Set Preview Quality to Low or Medium.
If you create a synced project, you can edit using the proxies files. To do this, go to the View menu, select Use Optimized Clips.
If those suggestions do not help performance, please let me know, and we can dive deeper.
