AA doesnt work properly in some games?

So ive asked this before but im getting realy frustrated about this problem. Hopefully its just a driver issue because ive tried all different settings in CCC. And this have also been the same before i used the dell v-bios. Right now i have it on standard and the driver 10.10. Ive tried booth Dells and Amds drivers so ive tried all drivers that work with my config. So probably more people than me must have problems with AA not fully work in games like Maffia 2, Bad company 2, Alien vs predator and now Medal of honor Tier 1. I can see that something happens when i have AA on but edges is still bad?? So what can be done, have i missed something or is it the driver that still need to be fixed

 

Yep chiefs. I am quite annoyed at AA with AMD/Ati as well. It seems that they don't handle AA very well and take a huge performance hit when we do enable it. Where are our 10.10 mobility drivers. CMON AMD...................

Most likely driver bugs chiefs. Not your hardware or eyes lol.

Cheers.

 

Well it works in some games but in all honesty when you are concentrating on the game and not looking at edges to check for jaggies, then it is barely noticeable.

 

I use RadeonPro to make profiles for games that won't use Vsync or AA. The STALKER series, for instance, will NOT enable Vsync even if the option is enabled. There's other stuff too, like texture LOD, which makes some games look amazing, and some others look like crap.

 

I just found that Aion plays smooth w/o AA or AF?

 

There are a few fps 'killers' that I've noticed. AA and AF and shadows are big ones.

 

Not really killers anymore given the current hardwares. My GTX 260M SLI handle AA better than my XFX 5870M despite being inferior performance wise. It's more of ATI driver issues rather than the demanding AA itself.

That being said, I don't really care about AA as long as I can play my games at 1920x1200 smoothly. At that res, AA does not really matter.

 

So ATI has more trouble than NV with AA due to stuff at the driver level, or the hardware level? Driver level can be fixed...eventually. And you're right, at that res AA isn't such a huge player.

 

Yeh I agree Nvidia GPUs handle AA much better than AMD/Ati GPUs. I have been experiencing the same massive performance hit in games when I turn on AA in games on the 5870s as compared to the minor fps hit under the 260s.

I normally turn off AA as well or set it to the lowest setting. Although I do try it 1st and if it works fine like in MOH Tier 1 I just leave it. MOH is not a really taxing game to run though so thats fine.

Must just be due to AMDs shocking drivers. CMON AMD. Lift your game oles!!!

Cheers.

 

I'd say most like driver lvl chiefs. I remember when Nvidia had similar troubles with ambient occlusion and AA + other stuff. Massive performance hit even on the latest tech GPUs however that all seems to have been improved drastically over the past year. So now maxing everything out still runs awesome. Just need AMD to do the same thing for us now oles. Then we'll be golden.

Cheers.

 

I was shocked when I see minor fps hit with AA on when I was gaming on my M17x R1. My experience one year before that (with G92 based 8800GT desktop) is you will get severe fps hit with AA on

 

AA and AF do most of you really know when to use them? or what they do?

And Vsync should ONLY be used if your framerates never dip below 60FPS otherwise it will have a negative affect on frame rates. For example if you are hitting max frames over 100(hypothetical) and min frames 60 or higher, and you have screen tearing then you can enable Vsync to remove the tearing and have no negative effect on FPS. If on the other hand you have a max frame rate over 100(hypothetical) and min frames of 50 or lower Vsync will have a drastic negative effect on FPS.

I just think it is unfair when ppl dog hardware and they enable 8x MSAA, 16X AF, and VSYNC + a high resoulution then are like wth?! Why doesn't this run good? maxing out all the settings doesn't mean poop the visual quality is not drastically different.
