As the subject says.

I wonder at what driver version did nvidia make the additional option to add custom resolutions?

Does the power strip program allow custom resolutions on older driver versions that lack this feature?

I saw a video from philscomputerlab on 1600x1200 res on 1080p displays using the custom res driver option.

Would be real handy to get it to work.. some games just dont work in widescreen no matter what you do. (hacks,cfg tweaks etc etc)
