After every edit I make I get the spinning wheel for 5-30 seconds. This includes switching to another sequence, making a simple cut, changing audio levels, etc. This is very annoying! I'm working with proxies at a 1/4 resolution preview. I've updated my graphics driver and Premiere, and I'm working off of the internal media drive, and I'm on version 15.4.1. 🤔
I've also watched a few YouTube tutorials on optimizing performance in case I was forgetting something basic. All those basic boxes are checked.
