I have been struggling and trying a lot of different things but i cant manage to start GTA without it crashing when it gets to the Rockstar logo. Game works fine with MSI AB and Rivatuner closed down, but not when its up and running.

Had a similar issue (crash right after the second R* logo), but I was only using Rivatuner. Fixed it by disabling stealth mode.

your a life saver, thanks

well thats solved
