I did lots more testing last night, including installing the newest AMD drivers to no avail. The only thing I did not try was to roll back to an older driver. I've almost completely given up but I might try that. The test I have been doing has been with Tatsunoko vs Capcom and consists of deleting the GUID shader for this game, deleting the two specialized shaders for it, then starting a fight with Ryu and launching the special hadoken move. Even with asynchronous ubershaders, this produces massive stuttering. Synchronous US is too taxing on my system in general.
I did run some tests with the plain old synchronous compilation method (no ubershaders) and the stuttering was even worse. I guess this proves ubershaders is indeed working for me but its performance is much worse than it was a few months ago for whatever reason. If rolling back the GPU drivers doesn't help, I'll just wait this out and let it resolve itself, whether through future driver or dolphin updates, or when I upgrade my hardware sometime this year.
