I was wondering about this question a long time ago, since I've been installing every single Game Ready driver when an update came out. I really didn't see much of a difference in-game. I don't have a powerful GPU, I have a GeForce GT 630. Do I actually need these drivers? Most games I play are Valve related - CS:GO, Portal, and also League Of Legends. I might install GTA 5 and play it on lowest settings.
