@Das Letzte Einhorn: Keep in mind that wine compiled that way will NOT WORK with many (most?) applications, wined3d should work but not wine as a whole. I usually copy wined3d.dll.so from it and use "O2" for the rest. That way I can use optimized wined3d for any game desired (just paste it in the game folder and rename it to wined3d.dll), and still keep compatibility.
