What games did you struggle 21:9 AWPC? I'm finding it's mainly GFWL games that suck with 21:9 (And "From" aren't great PC coders, so I don't expect 21:9 support there to work properly)
Aside from some menu problems, I've found 21:9 pretty good. SWTOR was perfect 21:9. Fifa 14's immense, seeing more of the pitch, I'm making some ridiculously good through balls.
Even playing Racoon City had proper 21:9 support for the game, running at 72hz it's really a nice experience.
Witcher 1 I'm playing through at the moment works fine for the most part if you lower lighting settings.
Watching Blu-rays is insane too, and anything that's 16:9 I just watch on the 23.5" Sammy, any games that don't work 21:9 I just stream to the Ultrabook 1080p at 16:9.
