Blackscreen

Run it as Administrator

This happens usually due to graphic drivers conflicts,remove useless drivers(for example graphic design tablet drivers).The problem may also occurs when you run GTA at a resolution that is different to your windows resolution. GTA tries to change the resolution and crashes

the game is crashing when i click launcher

if a game is crashing,then it has to be AntiVirus,it must have deleted files like razor.dll or any othere files in the game directory

i can’t change the graphic options, have tried to run as administator too. anyone an idea?

click space to save after you change graphic options

-Tips, If you don’t like the motion blur, press P ingame.

-Tips, If You lag to much or play the game at a certain FPS lets say 24fps and want a big boost, press (RShift+F10) to disable Occlusion (Sharp Shadowing). You will have to do this everytime you start the game and or pause it.
