Summary	04974: bankp, bosco, galagamf, gyruss, pacman: Speed is not at 100%
Description	This game runs at 98/99% of the original speed causing problems with audio. Also seems to me that inputs became unresponsive in bosco. The strange fact is I have no problems running drivers such as cps2, midvunit, seattle that are more cpu expensive. I have a i5-3570k at 3.4 GHz.

Ok, reproduced with ddraw/d3d and triplebuffer. Additionally I cannot disable throttling using F10. Many players using triple buffer with throttling disabled and only one thread to gain smooth scrolling, is it? Recently game driver (bankp) has been updated to 61,03 Hz so running this game at 60 Hz slowdowns do 98 %. In general something is with throttling not right (is it?) - works fine with multithread but to not work with only 1 thread.

No.08862 Scagazza Tester Aug 10, 2012, 18:58	Multithreading is on. Still have problems with these old games.

No.08864 Scagazza Tester Aug 10, 2012, 19:05	Yes disabling vertical sync works fine. Is it a bug or not?
No.08865 haynor666 Tester Aug 10, 2012, 19:15	I think we must wait for answer from dev team.
No.08867 Haze Senior Tester Aug 11, 2012, 02:15	no, it's not a bug if you use vsync you should also set your monitor to the exact same frequency, mame won't do that for you. you're telling it to run at 98% speed by turning on vsync at a different frequency to your monitor, which is why you get audio problems.
No.08868 Fujix Administrator Aug 11, 2012, 02:55	This is a FAQ. Those games work at 60.6060 hz, and your display is 60 hz. If you enable -wativsync, they work at 99 %.
