Just uploaded yet another fix for DX10 compatibility: Three small bitmaps that I had forgotten to convert to DDS format, which means that they would not render properly with DX10. The new bitmaps can be found on the Download page.
Unzip the archive and copy the bitmaps to the folder “Saab_35_41b3\texture\” and reload the aircraft. You don’t have to delete the old bmp files, the dds files will automatically take priority.
These files are intended for 4.1b3, although they will also work with earlier versions.
