This is getting pretty crazy. AC is unstoppable in his efforts to make the perfect Nvidia tweaking program. Heres what he has to say:
"Well the new detection introduced in .49 has been bringing plenty of problems but like usual time is the only essence to making sure the program is most compatible. In fact believe it or not over a 1/3 of the code is pure compatibility between the different operating systems and driver versions. This one looks sturdy. If you are using 21.81 drivers and overclocking does not work in the NVIDIA control panel there is nothing I can do (NVmax uses NVIDIA system). I think I'll have a little break now"
