Hello
http://headline.czela.net/Mirek/wine/Supreme%20Commander/ with GLSL and this is part of messages when playing demo game:
fixme:d3d_draw:drawStridedInstanced >>>>>>>>>>>>>>>>> 0x502 from glDrawElements @ drawprim.c / 991 fixme:d3d_draw:drawStridedInstanced Unsupported WINED3DDECLTYPE_FLOAT16_4 fixme:d3d_draw:drawStridedInstanced >>>>>>>>>>>>>>>>> 0x502 from glDrawElements @ drawprim.c / 991
I've encountered this when running some windows demoscene prod, with GLSL FBO's enabled. Try switching to pbuffer as it helped here.
