My native language is Russian and maybe I can't explain everything well, so sorry.
The presets in CP are managing only the global options which I can find and change in CP\Riva\NVtweak and so on. But as I understand your optimizations aren't ending on modifieng the general settings. BTW I've already asked a question about optimizations you are making with drivers. I didn't get answer but I think you are modifieng some advanced settings which can be modified only by editing registry too (or I don't see any reason in using your drivers, standart settings can be modified by everybody who knws how to get into CP

). So I thought that you can make for example 3 .reg files and add shortcuts to them. They will contain all settings, and advanced too configured to get one of the wanted modes.
