Manual control over Optimus?

My UL50Vt was stolen recently and I need to replace it. I absolutely loved the machine (aside from its size—I wanted that numpad, but I think it wasn't worth it), not to mention Asus' warranties, so I'm looking at the UL30JC, as well as the UL33JC, and maybe one or two others. I have a question about Optimus, though: is it possible to manually control it? I ask because I play a lot of very old games, including emulated, DOS, Win95 and Win98 and so on. I found it was very helpful on the UL50Vt that I was able to force it into either integrated or discrete graphics modes. Due to the odd things one encounters in trying to run very old games on very new computers, I came across many circumstances where the integrated graphics would work far better with a game, or the discrete graphics would work far better despite it not possibly needing the power.

So anyway: can I force an Optimus-powered machine to run a certain program using either the integrated or the discrete GPU?

 

You can:

whitelist a program, so it will ONLY ever use the nVidia or Intel

Or, set the nVidia or Intel as the defualt for everything (effectively setting one or the other).

 

Thank you! Will make my days of closing VLC and letting the screen flicker seem like a bad dream...
