As much as I love my 21:9 monitor it mostly sits alongside my main (16:9) monitor for the stuff that works well with it and definitely 2nd or 3rd place in terms of usage it gets
Its a really poor showing in my opinion. The pair of monitors cost me nearly 2k and they are nothing but a pain when it comes to games. Work wise they are wonderful 120hz massive real estate, what isnt to like?
Honestly before these I ran 4k and the experience in terms of games and just generally not having to fight the resolution etc was miles ahead. To be honest every game I have tried ran better at 4k with the exception of pubg but then even at 4k i was still getting in excess of 100 frames with decent settings, ultra draw distance etc.
Its about time devs stopped being lazy and catered to not just the lowest common denominator. The list of games with issues at the res is literally endless. Csgo for example supports the res but try playing the game at that res, there is something wrong with the engine that causes massive frame and server variance at 3440x1440 that isnt there at literally any other resolution. Even crazy 4k eyefinity resolutions.
I would bet money that of my 300 game steam library there are probably 70 to 80% that have issues at the 3440x1440 UW res.
