I thought this thread might be useful for people who play on 3 screens.

I currently run 3x1920x1200 screens and play with besel correction on 6170x1200.

The biggest difference I have noticed is that when there are particle effects that go right up against the screen. Such as slag in Borderlands 2 or Shroud in Thief. AMD drivers render them better than Nvidia. With the 670s Slag would take up my entire screen, this also happened with any other effect. It made it completely impossible to see anything. The shroud effect people complained about I never noticed on Nvidia but immediately noticed on AMD. It seems that those type of effects are very stretched and not properly rendered for 3 screen gaming. AMD still isn't perfect, slag is way too large but it is literally 1/3 the size it was using Nvidia.

I did notice a slight bit of stutter in Borderlands 2 that was not there with Nvidia, however Thief was much smoother (probably because of framerate increases.)

Also full screen videos on Nvidia Surround stretched over two the periphreal monitors a bit, this is not true on AMD. It fills the center screen correctly.

Overall I have not been disappointed yet. Hope this helps someone who is reading things about drivers etc and thinking of picking up some r9s at a ridiculously low price.

Thanks. Have you tried one card to see if Crossfire vs SLI is any different? I know performance will siffer but I'm just curious if dual GPU is introducing anything. :I'm Jelly:

I'm wondering if the "slag" effect uses PhysX, and now that you're on AMD you can't enable the highest PhysX setting... Slag effect was probably overdone with the highest PhysX setting.

^1 that is my thought. Rendering wise, there really isn't going to be a difference, unless it is a feature built for one card or the other, which PhysX does. Smoothness, features and what not may be different, but that sort of thing sounds like a PhysX difference.

PhysX creates a lot of debris on the screen in BL2. With PhysX on low I didn't notice a difference in the amount of slag between a 290 and a 780.

I'd love to try a triple monitor setup sometime. Sounds like it would be pretty immersive in some games.

Been asked this twice. I can disable crossfire. Obviously fps will drop. What would you want new to watch for besides performance impact?

Not too clear, was I? :)

Sorry, but just if there is anything negative performance wise due to the multi card setup. stutter, res scaling, failed monitor startups, etc...

Those screenshots look great. Really wide field of view.

Are most games plug and play for triple monitor or is there a lot of fiddling involved?

There are some games that do not support it well but they are much fewer and far between now. There is also a tool available to fix most of the games that do not support it. FlawlessWidescreen I believe it is called. http://www.wsgf.org/
