Hello,

I just found something very interesting regarding this vicious
slow-motion bug, at least for me it's a working workaround. It seems
that running 'wineserver' with a higher priority (I think, I mean with
a lower 'nice' number) than the game, prevents the bug from happening.

Until I found this I was running both 'wineserver' and the game with
the same priority, eventually trying nice levels from -9 to 19, but
the bug always happened sooner or later (but less with sub 0 values)
(it always happened tho on the rolling credits screen that appears
when you quit the game).

Using this it doesn't happen anymore, I can even let the credits
screen roll and it doesn't happen (while it always gone bad on that
screen, within a few seconds if not immediately). For example, in my
case I start first wineserver with a 'nice -n -5', then I launch
GPLegends with wine with a 'nice -n -3'. For more clarity, here is an
example how it would look like in a script to launch the game:

nice -n -5 wineserver
sleep 1s #wait 1s=one second, not sure if it's required or useful...
nice -n -3 wine C:\\Program\ Files\\gpl2004\\gpl.exe

Btw, I still use Wine 0.9.42 (because with more recent versions (last
one I tried is 0.9.51) performance is very very terribly stutteringly
bad (unless I turn sound off), but that's an other bug/story). But I
think this slow-motion bug still exists in these more recent versions
and this nice level "trick" probably works too.
