Playing VC without cheats or mods on the PC. I got 6 stars in a rhino and the lag started coming. (normally my VC is smooth and fast). then i paused and pressed esc to resume and it froze to a black screen. i had to restart my computer, what happend? all i know is its a tower with hp guts, windows 7 x64, and its old hardware so i cant use windows 8. what was that black screen for?
