AE 2020 Stroke unbelievably slow

[kiddiuk]

All my projects that rely on the Stroke effect have become untolerably slow since upgrading to AE CC2020, reverting back to CC2019 fixes everything, in fact CC2019 runs much, much faster in general. I'm on Intel 9900K/32GB/AMD RX580 + Intel 8700K/32GB/NVIDIA1080Ti setups, both running latest versions of Windows, and both machines suffer the same problem with the Stroke effect. We're talking 10-15second refresh rates on frames that render instantly on CC2019.

That's the problem with new Adobe software.  You instantly become part of the Adobe Unpaid Beta Tester Program. 

From time to time, you will see posts from Adobe staffers.  Basically they say, "We're aware that many users are having problems with the new software.  Please give us detailed information about your computer and all the software on it so we can come up with fixes."

In my opinion, that's not the job of a User.  That's the job of a BETA TESTER, which is something that Adobe chooses to ignore. You shouldn't have to guess at the necessary driver updates or use workarounds for poorly-coded software. 

But Adobe is of a different opinion -- they let YOU find the problems in their hastily-written code, and never mention anything about the problems incurred with incompatible driver software.

So I always stay one version behind.  When a new version comes out, I get the final update to the previous version.  I figure Adobe has made all the bug fixes to it that it will ever make, so it ought to work reasonably well. 

And I have to tell you, I am not happy with some of the features that were eliminated from AE CC 2019.

Yup. Same issue over here on a 2019 Mac Pro running 10.15.4.

Exported my projects back to CC2019 and everything runs beautifully.
