Well finally arrived
First thing I noticed was colors, nothing close to my S27B970. Viewing angles aren't great, don't really notice it side to side but very noticeable when viewing from a downward angle. Will try the settings VEGACORTEZ has posted and see if it can be improved.
Tried a couple of games out, just roughly what I noticed with fraps.
BF4 : ultra - Mantle - AA disabled (saw no difference with it) 60 - 80 (normally 70ish)
Tomb Raider : 35 - 70 depends on indoors, outside around 35 - 50
Grid 2 : 70 - 85
All in all very impressed, all these games are more than playable, Tomb Raider especially looks amazing. Think i'm gonna have a second play through.
I'm running on...
