The NGO
NVIDIA Optimized Driver is a modified version of the NVIDIA ForceWare driver. The main purpose is to satisfy the users with better performance,
image quality and compatibility. The NGO NVIDIA Optimized Driver can enhance your experience in
games, multimedia and general usage. This project is especially suited for enthusiasts and gamers that want to have the best
gaming experience.
This driver includes NVIDIA's new Control Panel. We’ve preferred to include the new Control Panel over the old one due to flexibility and stability reasons. The Driver has support for all GeForce/Quadro cards – including mobile series (Go) as well. This driver has a special compatibility mode option that provides better stability, and workaround for some known bugs.

Gisa, the term Forceware seems to be a marketing term used by Nvidia to describe the actual drivers and the software installed to support the drivers. The NGO drivers use the same installer and install the same software as what you have now. The difference is that they have been tweaked to work better for gamers.
I have noticed a big difference from one set of drivers to the next. For a long time I used the Nvidia 93.71 drivers because they seemed to be faster in Trainz. I would try the newest one but would end up going back to the 93.71 version. I find the NGO drivers after seeing them mentioned in a forum for MSTS. In the kind of routes I like to run, mostly rural mountain themes, I get about 25 per second.
By the way, based on the wonderful article on testing cited above. I have increase my -resourcememory setting to 1024. Trainz is running even better now.
