whats the difference between
forceware drivers and detonator
Forceware drivers are the newest, just a new name, basically. Although it seems that I have read somewhere that they are new from the ground up. They've been out for a while and went through quite a few driver versions. They are both nVidia drivers. If you are thinking about going to the latest driver, use the Forceware driver.
Unless you like to play around with Beta drivers, and like to change drivers a lot, I would suggest you use the latest official drivers from nVidia, which are Forceware. You can find them and a lot of other versions, right here at TechSpot, in the downloads section, or get them directly from nVidia.
The only difference is the name. Forceware is used for newer versions though.
