Aa & Af??
Ok..I look at video card benchmarks and reviews and I see that they use AA & AF during the benchmarks. I know what the initials stand for i.e. Anti-aliasing for AA, but thats all I know. I don't beleive I have it on my current video card. Could somebody explain it to me or point me in the right direction where I can read about it and understand its uses?
Thanks -Jerad |

Your card supports both, try them at all the levels, and watch as your frame rate drops. I do not like the way the picture looks with them enabled, 32bit color and 1024x768 res is more than enough for me. I think af has the least performance hit of the two. To run these options without much of a performance hit, you would need a gf3 or gf4ti card, or a ati8500 or better.

AF stands for Anisotropic Filtering, you can read about it here.http://www.extremetech.com/article2/...,559035,00.asp It basically another way to produce sharper images with your video card. I agree with Blakhart, enabling AA will significantly reduce your framerates, without a very noticable effect.

So as a gammer I don't want AA or AF enabled? If it gives me lower frame rates why would I want to enable it. So pretty much when they use the AA and AF in bechmarks, It really doesn't matter what it does to the performance if I never plan on enabling it. Another question. Is AA or AF enabled by default? or is it disabled by default?
Thanks for the link -Jerad |

AA is set to 'Let the applications control the level of anti-aliasing' by default in the nVidia control panel, and AF is off by default.

AA and AF are great if you are doing say everhack, where frame rate is not quite so important to players as, say, image quality. It is in most every card as a selling point. My first experience with it online game wise was bad. I kept getting my posterior handed to me by my opponents. What was wrong? Well, af and aa at max in 32bit looks great on a gf2mx, just dont try to move and you will be ok. Figured it out, set everything back to disabled and 16bit color, and I got competetive again. These cards are not for gamers. I suspect that yours being a pro will do ok at 1024x768 at 32bit color in most every game. Leave all the options off but do experiment with fast mipmaping enabled and advanced cpu instructions disabled. These may give you a boost in frame rates with little to no observable image quality hit.

Why would disabling 'advanced CPU instruction sets' give you a performance increase?

This from Omega, of Omega drivers fame. I tried it and it seems smoother. Dunno what'll happen in your sys, try it and see, you can always go back.
