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.
