I have a quad and run just fine on all 4 cores. If you're having trouble, it's NOT with your quad - something else is wrong.Q6600 G0 CPU 2.4 o/c 3.6Evga 680i A1 with P30 BIOS 2G XP2-8500 DDR2 1066FSB Mushkin 996535 RAM 5-5-4-12-2T320G 7200 HD partitioned for XP/Vista/Programs 2 - 74G Raptors in RAID0 500G 7200 HD for backup SATA DVD burner Evga 8800GTS 640 PCIx Kandalf LCS case w/ built in liquid cooling 850W Thermaltake power supplyVisit the Virtual Pilot's Centerwww.flightadventures.comRadar Contact Supporter: http://www.jdtllc.com/

I don't know, Gary - I got the same impression( you would not get Vista) when I first read ytour post and was about to make the same comment.

Gary-I want to thank you for starting this thread. Not only for being a true gentleman in the apology you gave above, but in getting me to try some different settings on my lowly 7600 card and 4 year old system after I gave you that nvidia list.I've only had fsx for over a year now-but somehow I managed to tweak another 10 fps to my satisfaction-I am getting a solid mid 25-30 fps now on this aging setup-with a few more compromizes I can well live with.When the next greatest chip comes out-I will make the move to upgrade but I am more than satisfied right now. Thanks for getting me to get in there and tweak a little more.http://mywebpages.comcast.net/geofa/pages/rxp-pilot.jpgForum Moderatorhttp://geofageofa.spaces.live.com/

Hmm I am single core too pIv3.2.Just goes to show no magic answer.Like you though I am waiting to upgrade my 4 year old machine for something greatly better.http://mywebpages.comcast.net/geofa/pages/rxp-pilot.jpgForum Moderatorhttp://geofageofa.spaces.live.com/

I have the quad and I get very slight hesitations every now and then if I run unlimited.Q6600 G0 CPU 2.4 o/c 3.6Evga 680i A1 with P30 BIOS 2G XP2-8500 DDR2 1066FSB Mushkin 996535 RAM 5-5-4-12-2T320G 7200 HD partitioned for XP/Vista/Programs 2 - 74G Raptors in RAID0 500G 7200 HD for backup SATA DVD burner Evga 8800GTS 640 PCIx Kandalf LCS case w/ built in liquid cooling 850W Thermaltake power supplyVisit the Virtual Pilot's Centerwww.flightadventures.comRadar Contact Supporter: http://www.jdtllc.com/

Hi Gary I dont know if you solved your problem or not but what I did and worked with my GeForce 8800 gtx was to disable the write combining in the display properties.Carlos
