Hi all. I have 2 short questions which may result in long answers hehehe.
1. What is AGP appature? (spelling??)
2. What does it do?
I figure the Mr & Ms Wizards of our loveable WinDrivers community would be able to answer this for me. Thanks all! <IMG SRC="smilies/biggrin.gif" border="0">
The aperture is a portion of the PCI memory address range dedicated as graphics memory address space. Host cycles that hit the aperture range are forwarded to the AGP without need for translation. This size also determines the maximum amount of system RAM that can be allocated to the graphics card for texture storage.
AGP Aperture size is set by the formula : maximum usable AGP memory size x 2 plus 12MB. That means that usable AGP memory size is less than half of the AGP aperture size. That's because the system needs AGP memory (uncached) plus an equal amount of write combined memory area and an additional 12MB for virtual addressing. This is address space, not physical memory used. The physical memory is allocated and released as needed only when Direct3D makes a "create non-local surface" call.
Win95 (with VGARTD.VXD) and Win98 use a "waterfall effect". Surfaces are created first in local memory. When that memory is full, surface creation spills over into AGP memory and then system memory. So, memory usage is automatically optimized for each application. AGP and system memory are not used unless absolutely necessary.
The size of the aperture does not correspond to performance so increasing it to gargantuan proportions will not improve performance. Many graphics card, however, will require a larger than 8MB AGP aperture size to work properly so you will need to set a minimum of 16MB for the AGP aperture size. Even then, you should set the aperture size at a higher setting so that it will be large enough to accommodate any texture storage requirements that your games/applications may have.
At the moment, the rule of the thumb is an AGP aperture size of about 64MB to 128MB. Increasing the AGP aperture size beyond 128MB wouldn't really hurt performance but it would still be best to keep the aperture size to about 64MB-128MB so that the GART table won't be too large. As the amount of onboard RAM increases and texture compression becomes commonplace, there's less of a need for the AGP aperture size to increase beyond 64MB. So, it's recommended that you set the AGP Aperture Size as 64MB or at most, 128MB.

aww man ya caught me, ROFL, I have not the slightest clue what AGP Aperture is <IMG SRC="smilies/biggrin.gif" border="0"> <IMG SRC="smilies/biggrin.gif" border="0"> <IMG SRC="smilies/biggrin.gif" border="0">Quote:

oh yeah and it's copy and paste :P
but the main point is to help someone, no matter where the info is from, remember Mr. Miyagi! About half the answers he gave were links to the MS Knowledge Base but it helped!!! <IMG SRC="smilies/tongue.gif" border="0"> <IMG SRC="smilies/tongue.gif" border="0"> <IMG SRC="smilies/tongue.gif" border="0">
I was impressed <IMG SRC="smilies/biggrin.gif" border="0">
ummm i better not
not worth it
Cut paste or off the top of your head, the answer was great! Thanks! I always wondered what that was in the BIOS setting. I had a major crash situation with EverCrack, and I switched my AGP (not going to try to spell it) to 64MB and all is stable and rocks the house. Thank you much for your time! <IMG SRC="smilies/smile.gif" border="0"> <IMG SRC="smilies/smile.gif" border="0"> <IMG SRC="smilies/smile.gif" border="0"> <IMG SRC="smilies/smile.gif" border="0">
YYYAAAAAAAAAAAAAAAAWWWWWNNNN!
I'm not impressed.
I agree.Quote:

Going to give a certain user a ego that he will fall over on very fast.............
Appears I was misunderstood.
I was not trying to impress anyone! As a matter of fact when confronted with the fact that I could have copied and pasted it I clearly stated that i did in fact copy and paste it!
i answer a question to answer it, not to boost my ego <IMG SRC="smilies/mad.gif" border="0"> <IMG SRC="smilies/mad.gif" border="0"> why make the user click a link to another site to read their answer?
The user has their answer and they are happy with it.

Next time give the site you ripped it from credit...atleast when people quote MSKB's they tell you it's an MSKB...
And these flames are totally uncalled for! I suppose that I'm supposed to actually write the drivers I post links to? This site is here to help people get answers to questions. Period. By the standards being demanded here, each of us would be expected to qualify every suggestion we post with where we received the info. I can see it now, "I read this in another forum"; "I figured this one out through trial and error"; "I found this solution in a readme file on the installation CD".
JMM, thanks for making the effort to help--something no one else who posted on this topic bothered to do..... <IMG SRC="smilies/frown.gif" border="0">
