I've been playing Dragon Age: Origins on my laptop for a few days, and it's be running well enough.  My laptop has a Mobility Radeon HD 5470 video card, so obviously it won't be able to play on full blast.  So far I've been running it on full detail, 1360x768 resolution, and no anti-aliasing.  I also had some screen tearing and frame rate issues, so I decided to turn v-sync on and frame buffer effects off, because the game said those would help each issue, respectively.  So, I'm wondering:  what exactly do frame buffer effects and anti-aliasing do?  What am I losing by having them off?

Not too sure about frame buffer effects, but anti-aliasing gets rid of jagged edges. Big hit on performance if you don't have a really high end system. Personally, I'd leave anti-aliasing off. Try it with frame buffer effects on and off and see what it looks like and decide if you want it on.

I think frame buffer effects have to do with processing all the environment and body lighting, light blooms, shadows, spell effects, etc. It allows for more features to display properly, rather than having a single light source (making the game look darker) or shadows on character's faces.

I imagine frame buffer might be just that - buffering, like in video, so it'll use up some ram to make these effects nice.
