Three display setup performance

I could have spent more for 4 gb cards, but that would have defeated the purchase (2 680's for < $1000 shipped), but it was a game changer for me. Now I enjoy around 40-60 fps on the "black death" track. PS all framerate settings are taken from this track.

The good news is that the game runs very well on one monitor, but if you really want to play accross three monitors you will need a SOLID system to run it.

Another alternative that gives a similar field of view is to do two projectors. You get a similar view to 3 screens, but at the cost of only rendering two screens instead of three. The other advantage you have of course is that you are not stuck with rendering in "native resolution". You can opt for a lower resolution (and it won't look like ass) on a projector and it will render fine, as opposed to doing the same thing with LCD's.

So you guys can get an idea of what resolution I'm using for my comments (except where noted) it's 5040x1050

Well that's pretty much what I wanted to hear: It might not be optimal for getting most out of three screens, but you can get it to run smooth and stable if you put enough hardware into it.

I will probably end up running it on 3 x 1280x800 resolution as it's the projectors native res meaning I'd end up with 3840x800. If I'd go for 3x full hd short throw projectors I'd end up spending a price of a car on it, but I can get lower res short throw for 500-800 EUR a piece.

So at the end of the day the configuration of three displays is such that windows just sees one big screen with 3x display resolution? And then clod will automatically setup proper FOV etc to accomodate for the extra wide resolution?

Would be great to see some vids from your rig to see how it performs!

I also wonder if GTX 670 would do the trick as in CPU charts they don't seem to have much of a performance difference.
