Update:

• I changed the virtual memory page to 4095 (it was 2024, with the system recommending 3079) to both hard disk drives available to my system.
• I checked the checkboxes and set in the Launcher's parameters (tab Advanced) the following values:

MaxMem: 12545
MaxVRam: 3851
(presuming I have a 4GB Graphics card, and 2GB + 8GB virtual from hard disk)
The graphics details was set to High.
I was able to proceed in the learning process without any lag or screen problems until I needed to open the map. When I closed the map, the program crashed.

Attached the dxdiag file of my computer.

The game hangs when in bootcamp the Altis gets loaded.
The game also doesn't show surfaces in bootcamp missions.
