There have been a few reports of slowdown related issues on these ST-V games. Most notable examples are 05188 and 06149 .

Hydreigon, these other bugs you mention reporting slowdown are most likely unrelated to this particular issue since this appears to be a recent regression.
Have you tried the save state I made before commenting? That isn't normal render related slowdown and shouldn't be confused as such.
We are talking like 1 frame per 2-3 seconds type of slowdown!

is this another one that's down to cam900? I know he made some STV mods..

there have been other performance regressions tho, ideally STV needs rewriting, or maybe modifying to use the mednafen code as the code in MAME is from a time when the platform really wasn't well understood.
