Friend tells me Anti Aliasing gives you higher fps... I'm confused.

post #1 of 7
Thread Starter 
Basically his reason for believing this is that it takes away some work from the CPU and puts more work onto your video card... but I don't know if i believe that or not. It doesn't make sense to me. He's been telling me this for like the passed year.. can someone either prove me wrong or prove me right? because TBH it seemed like it didn't help when ever i did do it.

Basically, your friend is an idiot. AA will always drop your FPS, no matter what setting you use. Well, unless you're CPU bottlenecked.

yeah.. i was like... no matter what you will use the CPU.. it will just use more of your video card. i'm glad to know that i was right. now i really wont take any information from this friend seriously lol.

I cannot imagine a scenario where AA improves framerates (aside from synthetic tests designed to do such a thing).

AA essentially renders multiple instances of the same thing...how can that make anything faster?

Someone please correct me if I'm wrong here.

Anti-aliasing is how you minimize the distortion caused by looking at a high-res image at a low res. It makes jagged things look smoother, which means more polygons, which just means more work for your GPU. Negligible (if any) CPU work is offloaded unless you're using onboard graphics.

LOL. Possibly the best use of an image I've seen yet.

And yes, your friend is.... misinformed to say the least.

No more polygons, no.

Modern implementations of AA re-render areas of high spatial frequency (i.e. areas the engine sees as 'edges') at high resolution, then downsample them to a lower resolution (the one the framebuffer is sending out) to reduce jaggies.
