Using an nVidia 5950 Ultra card on XP SP2 running the
lastest drivers (66.93) and then running a Source game
like "Half-Life 2", "Half-Life: Source", or
"COunter-Strike: SOurce" the display graphics of the
BOINC application using freeglut stops working. It only
displays an empty black box instead of the project
Note: Normally when it does work, the cooling fan on
the video card kicks in when displaying the BOINC
graphics, after running a Source game and then BOINC,
the black screen does not casue the card's fan to kick in.
It seems that the Source engine leaves the card in a
state freeglut can't handle.
I'v filed a bug with Valve. I've tried both the
current release nVidia driver and the beta and still
get the same result.
