For offline gameplay (story mode):
Rockstar had officially declared in a press statement that even middle-class graphics card NVIDIA GeForce GTX 760 as vie sufficient to have a good gaming experience. That's a lie! Recommended by Rockstar requirements are even less. However, it is with an NVIDIA GeForce GTX 760 does not even possible that the game displays even during the day shade and occurs sporadically violent FPS drops. Before a which says: I use latest video patch from NVIDIA and only those recommended by NVIDIA settings. The game looks especially during the day very pale and stutter occasionally! On my other PC components can not lie!
UPDATE (EDIT): The Launcher Social Club now offered me no offline play option more and now requires manual downloading of a new patch for Social Club. After manual Download this patch the Launcher attempts only to update the game. That's still not, it is still the error "disconnected from the download server". Ie I can not even play offline now - unless I cracke the game, but I did not want. The honest buyer is cheated out of his money. Incredibly something!
