I have hacked together a working solution to run 3d accelerated Standoff and Secret Ops using only free and redistributable software, specifically under Linux through a hacked version of WINE and no Microsoft system in reach. This guarantees that no matter what changes behind Microsoft's back, there will always be a means to run the Vision engine using new operating systems. This also means that a 3d accelerated Macintosh version of Wing Commander Prophecy will be forthcoming as soon as Apple releases their x86 systems next year.
Linux users may receive step-by-step instructions to run Standoff here.
I've played through the first mission of Standoff Ep2 and all the Standoff Ep1 missions under linux and have had 0 crashes. The only glitches I've encountered are as follows:
Ingame 3d cutscenes (not inflight) are sometimes drawn backwards.
If you have not locked a target, only ships in front of you appear on radar. This is remedied by 'L', but I rather like it.
