Aye it's a bit weird doing x2 windows programmes compared to my Z35 but it's not uncomfortable viewing wise.
FPS is where it really shines. A fair few older games suffer as distortion from 32:9 is quite noticeable. But it's not all games. PSO looks very clean and sharp. A fair few looked pretty bad. Hitman, Absolution, Just Cause 3, Warhammer Vermintide 2. Although the latter was mainly due to muddy textures imo.
My all time fav online FPS game looks very good at 32:9 - Red Orchestra 2. Although I have to force the resolution in game via a console command. The screenshot doesn't really do the game justice compared to how it looks in motion, but it's highly enjoyable and extremely engrossing. I did wonder if sacrificing GSYNC for a FREESYNC monitor would affect performance and smoothness, but in all honesty I think being 144hz is just as effective at keeping gameplay flowing well.
