Problems with Nvidia Optimus and Torque3D 1.2?

I posted something similar in a rather old thread started 07/25/2011:

I decided to start a new thread about it here in this section of the forums because I think the Torque3D Private area will grab answers more focused to Torque3D.

Anyway, I just got a brand new laptop less than a week ago which I spent a small fortune on. Here are the specs:
> Windows 7 Home Premium 64-bit
> 3rd Generation Intel i7-3610QM 2.3Ghz Quad Core
> Intel HD Graphics 4000
> Nvidia GeForce GT 650M Graphics with 2Gb GDDR5 memory
> 8Gb DDR3 1600 memory
> Dual 750Gb 7200Rpm Hard Drives
> 32Gb mSSD Hard Drive Cache

While waiting for my new system, I excitedly purchased Torque3D 1.2 as well as several content packs and tools like Torsion. With a system as good as this, I figured I would be able to run torque and create my worlds worry free. However, whenever I open up Torque3D it will not give me the option to run it with my Nvidia graphics card, it only has the option to run with my Intel graphics. The Intel HD 4000 still looks nice on high settings, but there is a noticeable amount of lag and if I were to start building decently large levels, I can see that being a big problem eventually. I would really like to use my Nvidia 650m graphics card but cannot for the life of me get it to work. I have even opened my Nvidia control panel and set Torque3D's .exe to work with Nvidia instead of the Intel graphics but that didn't even work. Windows is up to date, directX is up to date, and all of my drivers are up to date.

TheGasMan (the person who started the original thread in the General area of the forums which is linked to at the top of this post) had a very good point. Laptops with the Nvidia Optimus technology are flooding the market and most if not all the systems I looked at which used Nvidia had the switchable graphics feature. Does anyone know if this problem has been fixed yet? If not, are there any plans on fixing it? I can see this becoming a big issue in the future with so many systems being sold with the switchable graphics option...

Also interesting. Apparently it uses the frame buffer from the intel core. This is a buffer in normal memory. So it won't be as fast as a dedicated ram GPU.
