GFX-card controlled AA & Aniso SUCKS compared to application-controlled AA & Aniso - why?! :(

Hey guys could you offer some thoughts on this?

Ive heard and read a lot about how you "get better performance" if you let the graphics card take control of AA & Aniso filtering when it comes to games - as opposed to the application (ie the game) controlling it.

This has been suggested to me for FSX Acceleration and recently I read on a gaming forum about how it will help with TES: Skyrim

So I tried it out and my findings in Skyrim:

Application (Skyrim)-controlled AA=4, Aniso=4-----> very smooth game 35-40 FPS

AMD (Catalyst interface)-controlled AA=4, Aniso=4-----> 2 FPS

Yes thats right when telling my HD5850 to take care of AA & Aniso I was seeing about TWO frames/sec in Skyrim

Same abysmal performance in FSX.

Why is this..its not supposed to be like this Why is my system ass-backwards lol.

Im not crying too much since app-controlled AA & aniso = smooth gameplay...just really shocked at the nonsense performance when telling the card to take care of things!

Oh and this was with the latest AMD drivers.

Ignore this. Wrong window, my bad.

That must qualify as best post of the year

Because ingame settings are optimised for the game.

While CCC forced AA just brute force AA's if you will.

Most likely because you think you're forcing the same settings but aren't, or simply because some games don't play well with having settings forced on them.

Hmm ok..I guess! Thanks for all the replies, I was just curious about the drastic FPS drop. Will leave everything on app-control!

You have it the wrong way around. You are usually recommended to use in-game AA/AF when possible, as it is better optimised.

There are a few exceptions, for specific games (usually where modders have developped a new AA injection system, or to deal with a game that has broken or non-existent in-game AA/AF) - but those are exceptions to the standard rule.
