@CuriousArtemis - You just simply download an older version. When you do a driver search on say nvidia website, it lists all the previous drivers as well. As long as you use the advanced search. Hopefully this is a direct link to that search:
http://www.nvidia.co...aspx?lang=en-us
It should literally list like the last 14 drivers, and the dates of when they were released is right next to them. I wouldn't touch any of the "beta" ones, just the game ready. You'd be amazed the difference between two drivers. One could have massive fps improvement, but be completely unstable lol. Not saying that's going to happen, a bit of an exaggeration.
The other search only shows the most recent driver.
So after you download the file you just run it. I also never run it in "default" or "express" installation. You could say I don't "trust" them, with knowing what my computer wants. I always choose "custom" installation. Bout all I change for nvidia drivers is the "remove old drivers" or whatever its called. Should be a check box right below all of the things its installing. The most tedious part is restarting your computer.
But the idea is some drivers work better for certain games, and certain cards. All they are doing is tweaking them to get the most they can out of them. That doesn't mean you actually have to "update" to the newest driver. Sometimes there is major fixes, but that's only around the release of a new game. I say don't update anything if it works fine for you lol.
