According to the Microsoft site, the newest build of Direct X that can be installed on Windows 7 is 11.1 whereas 11.2 can be installed on Windows 8.1, Windows RT and Windows Server 2012 R2
I’ll update to Windows 8.1 and let you know if it solves my issue. Also the Nvidia driver is the newest WHQL version (GeForce Game Ready Driver for Grand Theft Auto V).
Thanks for your help.
