--- Comment #2 from bogdanb bogdanb+bugs.winehq.org@gmail.com 2008-11-18 04:16:51 --- There are several bugs causing crashes and/or abysmal performance (Fallout3), but it's not clear what causes them, so I'm sort-of going through all warnings spewed out and trying to clean them up.
Also, it seems that using only three-quarters of the vertex samplers is not so great in general.
