    Anybody know why two of my graphics cards are suddenly not used?

    Help please!
    Does anybody out there know why this morning 2 of my 3 graphics cards might suddenly become off limits to Boinc. See below for Log file highlighting this. Not used isn't terribly helpful, and as far as I am aware I haven't changed anything apart from turning off the computer last night and turning it on again this morning. I have turned it off and on again, and all 3 GFX cards appear to be working. What can set them to being "not used"?
    Hoping someone out there has some suggestions for where to look
    Cheers.

    Well I have learnt something!

    I checked and my cc_config had today's date and an earlier time on it, and when I looked inside it had a host of options that weren't there yesterday including of course "use_all_gpus" set to 0 which I have reset to 1. Also report_results_immediately was set to 0 which I would normally have set to 1

    Perhaps more interesting is how these values all got there and I am guessing it's because I was looking in BOINC / Options / Event Log Options this morning and when I was done I clicked "Defaults" rather than putting them back manually. I didn't quite expect it to give me an entirely new cc_config.xml and reset all the non-log related settings. Hey ho. Live and learn. Thanks to any who looked and thought. Cheers
