Tri-SLI in Linux, possible?

[BloodyIron]

When I say possible, I mean theoretically.

I've read the reason XP doesnt have Tri-SLI is because of a limitation in XP itself. I was wondering if anyone could comment on Tri-SLI in Linux in a constructive mannor?

I'm sure its possible, the Linux driver model is pretty flexible. I have no idea if nvidia implements it, but you might want to check out http://www.phoronix.com and see if they ever covered Tri-SLI in Linux

I can't see any technical reason why Tri-SLI wouldn't work in Linux, but at the same time I can't see any point to it either.

no, sorry.

NWay-managed multi-GPU SLI systems (3-way SLI and the new quad SLI engine) are only supported on Windows Vista,

question: why? linux drivers typically lag windows in performance by a large margin - especially in sli.

I'm meaning can it be implemented, whether it is currently is not what I'm looking for right now. Compared to example Windows XP.

can it? of course it can. is it? no.

Triple sli isn't even xp btw.

You know, I said that it doesn't in XP... TWICE. Did you actually read what I wrote?

Does anyone know if nVidia has any plans or intentions to bring Tri-SLI to GNU/Linux?

Where did you hear that?

I kind of doubt it, but I wouldn't really look forward to it either. Take a look at: http://www.phoronix.com/scan.php?page=article&item=860&num=1 In some cases, SLI in Linux is slower than a single card in Windows. I would rather see nvidia (and ATI) improve overall performance rather than porting tech (tri/quad sli/cf) that has terrible scaling to begin with.

A variety of forums, I can't recall where exactly. I would love it if you could prove me wrong tho

Yeah I have read their reviews. I am uncertain if it's due to the environment, shitty drivers, or games not being well designed for linux?

Well, the games are OpenGL on both Windows and Linux, so a bulk of the game code is going to be the same (with some changes for window system, and maybe input and audio, depending). The OpenGL library is provided by ATI/Nvidia on both platforms, so I'm going to have to blame ATI/Nvidia for subpar performance.
