I pretty good tool for sorting out the best settings for your card.
After playing FC4 and having problems with FPS and the right settings for about 6 weeks, i tried the Game Optimization feature on the Nvidia thingy and it worked a treat, now am on 60fps 90% of the time, and the game looks GREAT.
I didnt think much of it when it first came out, but it works now
Just thought it was worth a mention if any of ya got new games at Christmas and was getting bad FPS, then this is definitely the way forward !
I aint Optimized all my games yet, but i'll do it one by one if and when i encounter problems heheh.
