The only valid options from that list are: Code: -dxlevel 81 -fullscreen -w 1440 -h 900 -refresh 60 -console -heapsize 1024000 GhostRider wrote: > sometimes the game crash wen i try to join a server > sometimes the game make crash the system when playing / joining a server ( i have to reboot with the button on the case ) > sometimes i can play 30mn / 1h without any problem ... then the game crash ( close without any error message ) > very often the game crash just after i joined a server ( 2 or 3mn after joining a server ) You have to: 1. Disable "Steam community in-game" 2. Use patches available in bugzilla for font related problems in CS:S (see this bug: http://bugs.winehq.org/show_bug.cgi?id=7698) 3.
