Ok, here we go with some 3d history that can help you to understand the state in the 3d industry about AA.
AA was introduced some years ago in the fixed pipeline as a hardware/driver feature, so developers just needed to tell the GPU to activate it and the GPU did all the work. You even could activate or deactivate it from your GPU driver configuration. That is how fixed pipeline engines worked and still works. Of course in fixed pipeline engines developers are limited to what drivers and hardware can do (no great fX or effects, only common and standard things). Now we have non fixed pipeline engines, wich works with shaders, where developers can (and have to!) control all about the rendering process, which is extremely more complicated and time consuming, but we can have bump mapping, nice reflections and plenty of other nice FX, only limited by imagination, hardware processing time and time to develop and optimice it. Important thing is that now all is coded by developers, including AA. In this kind of egines AA is no more automatic and need to be manually coded as post process filter over the whole image. Thats why even if you turn on AA in drivers configuration in no fixed pipeline engines it do nothing. Hardware do no calculate it automatically anymore, not AA, not anything. Coding AA filter shader is not easy if you want it to be efficient and not blurring all the image. You need to identificate manually all edges and so on... So give devs a break, things are not easy anymore as we ask for more fx and eyecandy. It can be done, but need time if you also want a lot of fps.

Yeah, deferred rendering has made the formerly easy step of adding AA very difficult.
And that is why you see tons of modern games that lack support for AA entirely - games like Crysis, Battlefield 3, Dead Space, Mass Effect. It is hardly a problem unique to cod. |

Anyway if you are able to use FSAA ( Fixed pipeline AA ) it will crop your FPS a 20% or 30%, making the game unplayable in some systems, because is a hardware demanding AA technique.
Even so Luthier said that it will be implemented but guess that it will not very soon, remember that they are currently rewriting the graphic engine so it needs get working before add things. You guys should try until then my post-process SMAA configuration : It is not perfect so you will see some jaggies here and there under some circumstances but have no frame rate impact at all and does a high quality AA without blurring everything. http://forum.1cpublishing.eu/showpos...99&postcount=5 Last edited by Buchon; 02-04-2012 at 11:51 PM. |

I just tried it. It's not bad. Thanks.
I was using the FXAA, but online is not that good, because it blurs all the dots. It's hard already to spot planes at longer ranges and that post processing blurs the dots too much. So I wasn't using it online. Yours looks like it should work online. It still has some jaggies here and there, but it's way better then nothing. This thread was simply bait for the mods to have a field day with the "corrective actions". It's obvious people would argue about this. Just because some game on this entire market was released without working AA, it doesn't makes it right.

+ 1/Thanks for that one. Excellent job with a real good tweak to CLOD. I just change my standard to yours, because it work great for me. Great improve. ~S~ |

I added Buchon's settings to the JSGME selection some time ago.. You can dl ver 2.4 here JSGME FXAA and SMAA utils Enjoy

Awesome! Thanks for putting this together with the mod enabler. Thats what I use for SilentHunter 4 and 5 mods as well.
Loving the AA right now. The other planes don't look like they were built outta Lego's anymore. ![]() Last edited by Factor; 02-05-2012 at 05:17 PM. |

That was the easy part.. The guys to thank are the guys who made the tools and the guys like Buchon who spent alot of time using the tools to find the best settings for CoD
