Premiere Rush get's laggy during use and crashes at export

Hello all,

I have massive problems with Premiere Rush, which should be used to create fast and reliable content for our social media channels. Premiere Pro is a bit of overkill, and also I have to start using it more to become faster...

I'm running a not so cheap Lenovo P15s gen2...4 weeks old, all updates done, like BIOS and Win10, I'm admin on the machine.

Lenovo Thinkpad P15s gen2, core I7-1165G7 gen11, 32GB RAM, SSD, NVIDIA T500 quadro 2/4GB

Windows 10 64bit

Rush 1.5.62 built 61

Premiere Rush is constantly getting laggy, especially when I add titles and transition, I had a project that hung up completely last weekend when I probabaly used too mayn tilt/pan functions??...

Today I was very cautious with tilt/pan, used only for one picture and had to save/restart Rush a few times to get the export done, it get's stuck at a few points, then CPU goes up to 4.8GHz/70% load, the T500 get's up to 70%...sometimes I'm lucky, sometimes not.

Is it the machine, drivers, Rush...where shoudl I start? Filmora? ;o)

Cheers from germany

Mike
