Sluggish performance on Big Sur#156

I just updated to v13, hoping that the app would perform better on macOS Big Sur. Unfortunately, it’s pretty choppy.

I have Intel Core i5, with 16GB of RAM and an SSD. The app worked great prior to Big Sur, but took such a hit following the OS upgrade that I resorted to installing Windows on Boot Camp. Works great on Boot Camp, but I’d prefer to run native.

Is this a known issue? If so, are there any tips to address the problem in the current TTS release?
