Hello. I'm trying to run Asterix (Sega Master System) with BizHawk but the game runs slower than it should when it's throttled by clock (default). But if I change it to throttle by VSync, then it goes faster than it should. And I don't know what to do to play at the correct speed. I'm pretty new in this speedrunning stuff as I usually played it in browser emulators (and I had the game as a kid), so I'm probably missing something due to my ignorance. Thank you.
Was having a similar issue myself. Games had been running fine, but suddenly game was running slowing with Clock Throttle. Audio Sync seemed to fix it, but would still get some slowdown now and then. I noticed Game Speed somehow was changed to 75% for me so I changed it back to 100%. Runs smooth again now under Clock Throttle.
