Purchased 3D Mark 11 yesterday and posted some great GTX-480 based scores (top of the list for a Core i7 965 as of this morning). I'm glad I did the posting yesterday because today 3D Mark 11 no longer works. It hangs indefinately at the first Physics tests. I did what was suggested on a Futuremark customer support page: disabled the scan-pc option. That got me through the first Physics test and the Combined test. Upon exiting the Combined test, however, I get a nice big error message with lots of code. I hit "retry", it flashed the error again along with a Windows message indicating the program was not responding, hit "rety", and then it sat there indefinately. Had to use task manager to kill it. I have tried uninstalling, rebooting, re-installed, ensuring no other programs were running in the background, but nothing has helped. Per additional guidance on the cummunity support pages, I tried disabling the scan-pc feature and that seems to allow all tests to complete without error but the results are not considered official because the CPU and GPU info are blank. I've unregistered the software on my machine and uninstalled it for now. I'm going to wait for Futuremark to get this right before it goes back on my system. I hope this isn't interpreted as "flaming". Sure I'm frustrated, but I thought I would post this in case other members see similar issues.
