SOLUTION FOR ATI CARDS
======================
Thanks to Cyphox and vashren from XWA forum, I got 3D Acceleration working on my ATI R9 270 card :D
I will mention from the start that hex editing the exe file didn't work for me as the game crashed while loading a mission.
So I created an ISO file as Cyphox described.
As already mentioned by shanafin a few post above, driver compatibility was broken when Catalyst 13.11 was released. So the solution provided by vashren was to extract the old dll files from Catalyst 13.1 (when 3D was working) and copy them in the TIE installation folder, therefore bypassing the dll files from Windows folder.
He made an excellent guide:
http://www.xwaupgrade.com/phpBB3008/viewtopic.php?f=10&t=11187 Although the fix was for X-Wing Alliance, it works with Tie Fighter 95. All these games are basically based on similar engines.
He suggested that a similar approach should be done for NVIDIA. I am sure that here on GOG, the community will find the solution.
For those who want the quick method, I have uploaded the dll files in an archive on WeTransfer:

L.E: For the record, I am using Catalyst 14.6
I cannot find a aticfx.dl_ file in 13-1_vista_win7_win8_64_dd_ccc_whql.exe. I can only find aticfx32.dl_ and aticfx64.dl_. Both in the folder, either in the folder, either renamed to aticfx.dl_ and neither in the folder leads to the exact same result for me, .5 seconds of glorious, beautiful 3d hardware acceleration and then crash to desktop.
That WeTransfer link does not work for me, it says "Sorry... The download isn't available anymore."
