This technique only works for integrated GPUs that use shared memory. Transferring the frame buffer to and from main memory will seriously impact your performance, unless you're already storing it in main memory.
While an 8800GT may offer more in terms of floating point operations, the modern CPU still has more raw power. I would really like to know what you heard that you are basing that off of.

And as the article pointed out, the MLAA method doesn't happen in real-time, it happens to pre-rendered frames (making it easier for the CPU to do handle due to it's weak floating point operations).

And the thing to remember is the GPU is still using most of its power to RENDER. If you start throwing in AA/AF and other effects, the GPU can run out of resources pretty quickly. Keep in mind as well that your common gaming system these days is going to have 4 CPU cores and 1 GPU. Balancing the load is going to benefit just about any system.

More and more it seems gamers are stuck with a GPU at 100% load and a CPU twiddling its thumbs. Something like MLAA on the CPU could help with that tremendously. Obviously it might not be ideal on all engines and all scenarios, but having the option to run AA on the CPU could help tremendously in certain applications. I think that is what the article is stating. The option is there if devs want to implement it. I can't see Intel even wasting time on something like this if it is as bad as you make it sound.

I think this sounds pretty great, I wish developers would utilise CPUs more.

When I'm playing games mine just sits there using maybe 10-20% of overall power, so there's a lot to play with. I'm sure there is more stuff that CPUs would be good at than just AI and physics.

In any case, I just wish devs used the CPU more, and made better use of multiple cores.

Isn't Intel just thinking of doing something similar to the PS3? It uses its SPU to do MLAA I think?

Although on my PC I pretty much always use MSAA, if MLAA is implemented well (as on a few PS3 games) it actually looks amazingly good, and is very 'cheap' in terms of performance.

True, I don't like the whole image blurring that often occurs, but as I said, when it's implemented well it's an excellent technology. Always prefer it to jagged edges...

EDIT: Corky dorkelson was clearer than me above, read his post also!

^

this attempt sounds just like when intel tries to make a GPU. ya know, that thing call Larabee that was epic fail

simply put, intel is beast at CPU but sucks at GPU. just leave GPU to Nvidia and stop researching graphics tech. intel should just focus on CPU and chipset.

but MLAA may work wells for APU. but who play games with integrated graphics

and I believe the typical gamer's setup is a fast quad-core and 2 midrange or 1 high-end GPUs.

With lots of cache, 8 MB or more, it's going to be SWEET I think, take a load off the graphics card = win here in APUs, provided it's a quad core or higher.

Could you imagine a 6 or 8 core computing 30%+ the graphics load?

I think it's a brilliant idea, let's see how this fairs, I usually turn off AA because it makes my weaker graphics card weaker!

All this gets us is less GPU load, which in games would be useful. The CPU is rarely your bottleneck anymore so the more stuff you can process on it the better.

I'm sorry, it seems you've never met my rig....
