Summary	02506: All Sets in fuukifg2.c and fuukifg3.c: [possible] Noticable slowdown while performing full screen frame buffering
Description	The speed of the game is slow. I do not think that there is a relation with the performance of the personal computer.
Steps To Reproduce
Additional Information	This was from a removal of a speed hack in 0.116u2. There is still questions as to which (pre or post 0.116u2) implementation for full screen frame buffering. It's noticeable, for example, in gogomile/gogomilj when the "DEMO" play screen shows up with the water rippling effect on the background.
Github Commit

Flags	Possible
Regression Version	0.116u2
Affected Sets / Systems	All Sets in fuukifg2.c and fuukifg3.c

I found an old thread which explains something: http://www.mameworld.info/ubbthreads/showthreaded.php?Cat=&Board=mametesters&Number=126636 However a way to get rid of slowdowns is to reintroduce that old hack. This will never happens.
No.02748 Haze Senior Tester Oct 10, 2008, 17:51	the sprites are probably framebuffered anyway (they're need a frame delay, which usually indicates this) so raster effects probably aren't meant to work on sprites anyway. The old hack was probably actuallly more accurate than the current hack.. but hey ...

No.02990 Tafoid Administrator Nov 4, 2008, 14:03	True. Updated the drivers effected. There is still dispute whether or not this is a bug or not - depending on the the original hardware.
