General settings

Frame skip
: normally should stay on ``Automatic''. It can allow you to have a fine tune if you are running raine on a very slow computer which drops frames all the time, and you want a constant frame rate anyway.
Triple Buffer
: it's to try to improve display quality, but it deos not work with all video drivers and requires some more cpu power. With most modern monitors, you should be able to leave this off.
Limit Speed
: except if you want to run some kind of benchmark, you should leave this on. If you turn it off, raine will try to run the game as fast as it can, making it totally unplayable most of the time !
Vsync Palette
: This option is for despearate cases : when your colors flicker you can try to turn this on, but it might be slow. Some better things to try : in windows, upgrade your video driver. Try to run the game in 16bpp.
In DGA 8bpp, if you use the default allegro library it will automatically synchronize the palette whatever is your setting. So the palette cpu time should be around 10-20%. If you use the patched allegro version, or if you use a raine binary from an official distribution, then the palette WILL NOT be synchronized by default. It's usefull because most games don't change very much their palette during game play, so colors don't usually flicker at all. If they flicker too much for you anyway, then turn this setting on.
You can also try the fast_set_pal setting in raine.cfg :
fast_set_pal = 1 is the default. In Windows if all your colors are bad in full screen with this setting (for 8bpp games) try fast_set_pal = 2. This setting will have no effect in windows 2000 and windows xp, because these OS forbid direct access to the palette. For the same reason it won't work in linux DGA or X11 drivers, but it will work in linux svga and fbcon drivers ! In dos, it should work everywhere.
Auto mode change
: When raine knows for sure which video modes are supported by your video hardware, it tries by default to choose the best mode for the game you are loading. It does not change the color depth though, so if you see the palette cpu time rising (F11 key by default), then it's time to switch to a higher color depth...
There are rare cases though when you might want raine not to change the video mode. That's when you are running with a crapy monitor which does not like mode changes for example, or when you want to run the raine debuger (which requires a large screen of course). In these cases you can turn this ``Off''. The setting is automatically saved by raine.
