After installing CD (ETERNAL took, CDs halt ..) wanted the game does not start first, after looking in the Windows Event Viewer to was unfortunately not smarter than before.
Then I stumbled in the Forum a notice that Rockstar do not like overlays of any kind. Looked short and lo and behold, Geforce Experience has a built-in service that starts with if you do Shadowplay on.
Service stopped - problem solved!
Meanwhile goes Fraps, I wanted to see the FPS to be able to adapt my details just like.
I play with a 4790k, 16Gb Ram and 2x970Gtx in SLI on an Asus Pb287q with 4K resolution.
My system is not enough to get everything (except AA, it takes no more at 4k) to turn on max.
A mix of high and very high contrast settings runs fine at constant 60fps.
I had only a little spongy feeling when playing, but after I Vsync in the game and switched to the drivers themselves to have then even that was gone.
Criticisms I actually only in the control.
On the controller, everything is multiple functions, depending on where you sit vehicle degrees - that's not readily during Pc, then mule Gta for double occupancy.
Fortunately, you can "on the fly" between mouse / keyboard and controller switch.
To fly, jet ski races, etc. I suppose then the controller - land vehicles can be wonderfully operated with keyboard on the other hand.
When shooting mouse / keyboard is always clear.
Online waits think you are limited.
One of us had at first some problems with disconnects or lags, in which case, however, it turned out, the Level3 in Frankfurt totally herumzickt (only one hop).
Say 50-80% packet loss, lasting 24/7 - even Diablo3, Dota or Path of Exile were virtually unplayable.
His Stream to Twitch also ripped off all the time.
It may not always be to blame the GTA Server.
Bottom line, I'm satisfied, the game is fun and brings a great atmosphere!
