stuck at loading Valcan system
 

computer not do anything, Ctrl + Alt + Del shows "programme halted"

tried severial times, not working from the automatic saved file

so, adjusted every setting to lowest, reloaded an earlier game, worked out after a good half hour.

:(

happened again while chasing SAM
looks nothing to do with grapihc setting, just some problem with saved file

Hmm, I did not have a problem in loading Vulcan system (or any other system in game). Try an earlier save.
