I've taken a look at several games that showcase Surround Gaming, so let's see if we can't tie together a few things:
Performance was much better than I would have anticipated
Glitches that plagued early drivers are a thing of the past. I had no issues playing any of the games, outside of those items listed as implementation limitations.
Apptimizer application makes enabling/disabling the feature a snap.
Parhelia has enough power to make Surround Gaming a useable feature.
Let me take this opportunity to reinforce something that I've said a few times already just in case it hasn't quite hit home yet. Surround Gaming totally rocks and I don't see myself ever going back to a single display. It really is that good. As a litmus test, I reinstalled my previous card to see if there were any compelling performance reasons for going back. I played pretty much all the games listed in this review and can honestly say that this simply was not the case.
I wish there was a way to allow you to experience Surround Gaming first hand because screenshots don't do it justice. As it currently stands, Matrox has been able to get some 34+ games to support this feature and the list is growing. Based on what I have heard regarding future support, you can be assured that this number will grow in the future.
The disturbing thing about this feature is the lack of coverage by the main hardware review sites. I understand that not everybody can either afford to purchase the necessary displays or desk space required for Surround Gaming. However, I can't fathom why these sites haven't taken the time to investigate this feature more closely. If nothing else, to at least discuss the possibilities from the point of view of an avid gamer.
Every person that has either seen my setup or heard me talking about it left wanting to, at a minimum, see the thing in action. In some cases, they were willing to go out and get one for themselves.
