AGP aperture size recommendation please...

[Artosoft]

Please, as above. My card is ATI PowerColor x1600pro 512mb AGP.

Especially for playing Civ4 Warlord.

Thank you in advance.

For any card regardless of the size of the video RAM, 128mb aperture size is enough. Any higher and you just use up more system memory. The difference in speed is only very slight anyway so saving the memory is the better option.

This is generally true, but for Warlords, a 128 meg video card may need a 256 meg AGP apature.

Thank you for replying.

My AGP VGA card have 512mb. So, should I increase AGP aperture or just leave it at 128mb?

Thank you in advance.

Its irrelevent. Dont even worry about it.

Grab a benchmarking tool and test differet aprature settings, the scores will be near identical from 64 to 512.

If you google theres 100's of FALSE articles on the net about what agp apreture is even for.

In general, 64-128 are fine still for all cards. If you have a lot of extra RAM (NOT the video card's RAM), then 256 may offer you some slight improvement in some games. In most cases, as has been stated, the performance differences from 64-256 aperture settings are pretty insignificant.
As stated in the linked article, if you have more VRAM on your card (like 512MB), your need for AGP addressable memory is reduced.

Thanks for all the replies.

I do search on this topic, and a good/make sense explanation is:
"AGP aperture size doesn't increase graphic speed. But, some system like ASUS need at least 64mb. It is reserved for additional VGA card's memory for the case of VGA card memory run out. AGP aperture memory doesn't mean it will consume main memory all the time (it is only used main memory for additional memory when VGA card run out of memory). If VGA card use AGP aperture memory, it will slowing down the graphic (because VGA card's memory is faster than main memory)."

So I will stick on 128mb AGP aperture size.

Thanks all!
