--- Comment #35 from max@veneto.com 2008-09-21 04:38:26 --- Well, digging a bit more I discovered that, for Autocad, the function used to output texts inside drawings (not the menu and toolbars ones...) is
PATH_ExtTextOut() in dlls/gdi32/path.c
Making this one a no-op speeds up Autocad but without TT fonts inside drawing. BTW, I found another bug about autocad TT fonts... it's a display problem that I noted before. Fonts are displayed erratically depending on their position on screen, it seems like they're rotated out of the viewing plane. I'll try to investigate a bit more on that function. Can you please try if your app speeds also up disabling this call ?
