I'm using a combination of the "Tomb Raider 2, 3, 4 Widescreen Patch" (which conveniently also works for TR5) and dgvoodoo2, and it works perfectly (well almost - there sometimes are playback issues for the FMVs but I don't mind).
I'm using the GOG version.
Have a look here for more information (and the tools I mentioned):
