I think STiFU has a good point regarding children, and I too have my doubts about 3DS since using one, not in agreement with some other points but I see no need to get into that debate. I respect his opinions. That is my view too, acknowledging some exceptions. Anyway... Thanks for the input folks. Glad to see there is at least a little interest in this. Partol, are you the chap who posted the IZ3D/3D Vision solution for 'NewDark' over on TTLG? I just saw it & tried it out the other day, I was over the moon to see it working, it does indeed look wonderful. Yes, you are right, now TDM is the only reason for me to keep my old hardware. If I try it out with the legacy Nvidia drivers, I will let you know if/how well it works. I'll also discuss a build before putting the rig together, to give myself the best chance Good question. Somebody did post a few years back on the IZ3D or MTBS forum, claiming to have got Doom 3 working but was annoyingly evasive about the exact method. I think someone else eventually confirmed it, and it was extremely hard to do. Bottom line, there are anaglyph screenshots of 'old' Doom3 up on the forum, and they look about as good as you can get with anaglyph. So creating the two views (and having convergence & separation controls?) wouldn't be too hard - as for display options, side-by-side/top-bottom would take care of most 3DTVs (albeit with some loss of resolution, but in practice I've found it negligible). But what about monitors & shutter glasses designed to work with 3D Vision or AMD (which I'm guessing must be the most common display type for PC gamers)? How would you get them to activate? Another idea, just for the sake of discussion... what about a Direct3D renderer? Like I say, I'm out of my depth here, for all I know it might be a HUGE amount of work & not worth it. But if not... D3D9 might make TDM 'just work' in Tridef, IZ3D and 3D Vision. Are there any other reasons (besides s3D) why D3D would be more desirable than OpenGL? EDIT: I see from other discussions this would cause cross-platform problems
