    Hmm,

    It's a stretch, but could this mean support for 3 monitors while gaming? Now THAT would get me excited about SLI! =)

    Would be ace if they went Tri Monitor setup for gaming. Would be a big reason to go SLI.

    Two you can do just fine now simply by dissabling SLI, eh?

    You get three heads usable if you turn off SLI, with two boards in SLI, at the moment.

    That works in games too? :|

    I think so. And outside of SLI, too, as far as I can tell. If you have boards with mismatched caps, the app sees the caps of the weakest board, apparently (accelerated 3D over two or more heads, with the possibility of mixing GPUs of different types).

    I'll see if I can get 3D acceleration over two heads (I've only got two readily available monitors, otherwise I'd try three) in non-SLI, SLI mode (if that makes sense) , later on. Got some 6800 Ultras burning away on some benchmarks atm, for some strange reason, so I'll give it a poke later on :wink:

    I am sorry but 3D APIs did not work this way in the case of multihead configurations. The game will see every head and need to programmed for this case. I know that the MS Flight Simulator engine supports this.

    nVidia works on a SLI driver solution that will combine multi heads to a single head for the API.

    I'm probably thinking of that, after seeing some driver tooltips today (I was working on ForceWare 77.62 earlier, and saw some info that led me to write that post above).

    I'm not familiar with D3D and OpenGL, so I don't know if these APIs allow asynchronous processing & amount of overhead there is between API to machine code translations. If they allow async processing, one could post request from calling thread to worker thread - and thus release the calling thread to do something else. Obviously this decreases performance on calls where overhead that posting request from thread to another causes is greater than overhead of API to machine code translation, or if you have something else running on the other processor (which might be true with next-gen game engines). But then again, I know nothing about graphics programming - threading is what I do.

    Is ATI offloading vertex processing to the CPU, as NV describes themselves as doing now?

    There was a certain resonance in that part with the recent patent mentioned in the Tech forum.

    So, how's that "new SLI UI" striking you? :lol:

    Yeah, yeah. . .wait until Tuesday night (where I am anyway). . . 8)

    There's a new UI? I thought these guys were (p)reviewing with the 77.62's that were leaked.

    Here's the tooltip I'm talking about, for reference:

    Rys,

    Sweet! Man if you could run games rendered in all three monitors like Matrox's surround view that would rock. It would actually make me interested in SLI with my 6600 GT (DFI NForce 4 Ultra, hmmm). Hmm, $387 shipped for (3) 21" Sony Trinitron FD Flat Screen oem IBM P260 DVI+SVGA .24mm 1920x1440@75Hz Grade-B monitors. =)

    Thankx for you input Rys. What site do you review for so I can check it out? =)
