I have Trackmania nations here that uses it for loading text. With the current
git code, the text is missing and the game unplayable. With the tex() forward
the text looks blurry and ugly. It is playable with the forward hack, but not
Honestly I don't expect that extension to get out of the limbo it is in
anytime soon. It has been in this state for I think two years, with no
progress. I think it has been standardized as part of the Shader Model 4
functionality, but on dx9 ATI cards it is all we have(and on dx9 Nvidia cards
the NV asm extensions are all we have)
