Random educational PC gaming post:
A driver level feature that is often overlooked and completely forgotten is Nvidia's forcible Ambient Occlusion. While pretty common in modern games it is a really neat thing to add in to random older games that they supported with it, while not looking overly high-tech and absurd against older graphics. The concept is the same as forcing anti-aliasing. Check the list in Nvidia Inspector to see if the game has a compatibility code or another game from the same engine does. Select the code and then check off the the force AO option and select the quality level.
I was messing around with Fallout: New Vegas this afternoon while preparing for my final achievement run and I snapped a couple comparison pictures. I recommend opening them up in separate tabs and flipping between the two to best observe the subtle, yet depth adding effect.
Example 1, Building Interior:
Ambient Occlusion ON
Ambient Occlusion OFF
Example 2, Building Exterior:
Ambient Occlusion ON
Ambient Occlusion OFF
I tend to forget about this feature and I'm pretty sure most people buying Nvidia cards don't even know it exists. So hopefully someone finds this useful or enlightening.
Couldn' tell which screenshot had it on and off. Thought the ones with off looked better so yeah.. think I can live without it
