************ GIMP ALERT!!! **************
If you are running a Maxwell card, pay close attention.
Latest Nvidia drivers 365.19 look like they are gimping Maxwell cards
Proof:
Before updating drivers to 365.19
Prior to installing the new drivers, I ran some tests with 3DMark Firestrike Ultra 1.1
I was averaging around 7820-7837.
See results for details

After Updating to 365.19 my Firestrike Ultra scores have dropped by about 1000!!!
I ran 6 different steps (stock and overclocked) and I am averaging between 6200 - 6907
So far, I have been unable to break 7000 with the exact same config:

Note: This is only one test system, so we need more data to be sure. If you are running a Maxwell card, please run tests of your own, and compare with your previous Firestrike scores. I havent tried running Firestrike Extreme or other benchmarks as well, so it might be an issue with 4K only. I have reviewed my results many times over but can find no discernible difference in my config exccept for the change in drivers. Please review my results and feel free to point out any inconsistencies I might have missed. As I said we need more data .
If these drivers have been gimped, it is in everyones interest that this is discovered and exposed. Dont expect WCCFTech or any other tech journalists to do their homework. We are not the ones paying their bills.
Thanks for sharing your feedback.
