Very comfortable!
I went from a 27" AOC, which was already good, to this 34" Fox Spirit!
It's a real comfort to be in front of such a screen, its price is really "low" for an Ultrawide and personally, it fulfils its role perfectly...I do a bit of simracing (Asseto Corsa) and really no problem.
I do a bit of simracing (Asseto Corsa) and really no problem, in the office, I draw a lot in 2D/3D, and I was worried about doing this kind of thing on a curved slab... well it quickly passed, because the rendering is more than good, and without any discomfort!
In terms of settings, I simply modified the white treatment so that it didn't 'burn' my eyes.
A faultless performance!
