I saw some info on other forums that Apple doesn't know about this issues. We should post about this problem not only here.
yes I know. I went back to 12.2.1. I'll wait until the next OS update comes out
 
Be aware that if you're running a 6800/6900XT there are serious performance issues with 12.3, my geekbench score dropped by about half.

Same with RX 5700 XT :(

I found my Metal and codec performance issues were due to setting refresh to 120hz, using 'variable' performance is normal.
 
I had the same problem when updating my hackintosh.

Hardware:
i9 - 9900k
Z390m for games
Rx 5700 xt - Sapphire

I added an SSDT that I had here at the time of Catalina and it solved the problem.

Confirm!

SSDT brings results to back.
Apple Motion is OK. Still testing under Blender (some results are different a little bit about ~80-90% of full performance of opengl under eevee engine).
 
Have same issues with AMD Radeon RX 5700 XT 8 GB
Same with the RX 5500 XT 4GB. Atrocious lag and even freezes for moments at a time after updating.
 
I have 2 different machines with 6800XT and 5700XT. Both of them are really laggy with 12.3
 
Same with RX 5700 XT laggy with 12.3
