The PC version is absolutely outrageous.
The graphics are a dream and in the first-person view a whole new gaming experience.
With MSI GTX970 G4 very smooth playable, at constant 60FPS.
Graphic Driver required.
Otherwise, I have from the first minutes of the game no problem with GTA 5, which already surprised me.
On release day, there is almost always little problems :-)
If I could I would give it 10 stars. Top!
