Queston: How much does Anti Aliasing effect framerate?

#1Mudkipz6255Posted 10/10/2013 11:09:26 AM
Noob question I know.

I'm trying to decide on a graphics card but most websites run their benchmarks on max setting WITH AA at its highest.

If let's say Crysis 3 ran at 15 frames at 1080p max settings would turning it off result in 1 extra frame? 5? 10?

Well once upon a time, AA essentially meant every frame had to be rendered twice.
2X, twice
4X, rendered 3 times, etc.
So if your GPU was struggling, it would potentially half your frame rate.


But, anti aliasing has improved since this was true, I don't know anymore.

Thanks for the lesson, wasn't aware exactly what Anti Aliasing was doing.

^^^^^
Not being sarcastic lol thanks

It depends on many factors:

a.) Resolution game is running at

b.) Scene complexity

c.) Type of AA used (MSAA vs FXAA vs CSAA etc.)

d.) efficiency of game engine/in-game AA

AA doesn't mean it renders the frame twice. Its just another step or steps in the rendering stage where certain processes try to remove the aliasing which is just another word for the more commonly known 'jaggies'.

Performance can be all over the place so its not a good indicator of 'value' when looking at benchmarks.

Give us your budget and someone will recommend a card that would be best suited.

That describes SSAA, not all AA.

Thinking of around $200-230 -ish.

Not looking to go much higher as my wallet doesn't think the performance improvement from there justifies the cost.

Also I'm mostly looking at MSAA numbers

Ah wrong range.

$150-$200 is what I meant. Thinking of checking out the new R7/9 AMD's coming out with.

he did kinda cop out of that response at the end of it. He wasn't claiming it was definitive in any way.
