--- Comment #14 from Sergey Isakov isakov-sl@bk.ru --- If I disable s3tc in the table gl_extensions_map then the game is not started with the message about "not supported" In the log there is line ~~~~ err:winediag:wined3d_texture_init The application tried to create a DXTn texture, but the driver does not support them. ~~~~
PS. I have full DXTn decompression support.
