(Try#2 - Also fixes Operation Flashpoint problem which was introduced) This is the first patch which looks at the performance of changing the textures on a texture unit. As was pointed out to me by Lucho, certain information is per texture unit and hence not affected when a different texture object is bound. This patch on my machine changes the displayed fps by the Billboard sample from 30.6 to about 42.6. [Actually it was 43.0 with patch b, but I dont see why!] There is still more optimization which can be done here, but this is a start. Let me know if anyone notices any regressions with this one. Changelog Only reapply the texture states necessary when a different texture gets bound to the same texture unit. Jason
