EDIT: The spring rendering code has some sections which handle DXT/S3TC compression (which is used in .dds). My ATI driver does not support DXT/S3TC decompression, so the problem must have something to do with S3TC.
But if all the textures are BMP and TGA (which don't have any compression, except RLE), how there can be problems with textures and S3TC?

Well, im as much as a layman about this as anyone, but heres what I think happens (anyone knowing better please correct me or feel free to edit/delete this post) :
3do's use 1 texture per face, so each face has a UV range of (0,0)-(1,1) Thus each face uses 1 single texture. Now having the gfx card switch textures bindings to a new image on _every_ face is slow, thus undesirable.
What the engine does instead, is it takes all these per face images, and tiles them on a large texture, then transforms the UV coordinates of the faces to correspond to the correct part of the large tiled image. Somewhere along the ATI driver update, functionality on a pathway related to coordinate generation/transformation was changed, thus resulting in the UV's not being transformed from the (0,0)-(1,1) range to their corresponding small areas. So the gfx drivers map the whole tile map to each single face.

I have the exact same problem with my 4830 running 10.5 drivers. I like the drivers though cause they fix all the longstanding issues in IL-2 1946. Why can't spring be updated to get away from such ancient compression? Just saying I have no other issues with anything else.
There should be a big warning message when installing spring. As Ati is very popular at the moment and having the latest driver installed is not unusual either, a big chunk of newbies that install spring today will get gfx errors making them cry and uninstall spring.

That's a good point. I would hate to jump through all the hoops just to find that the textures are screwy. Then again they might pick a game that has s3o's...but still a polite heads up would probably be...well polite.
