RayProudfoot Certificates/Ratings/Crew Stations: "AGP Aperture setting with 128Mb cards" 08-20-02, 21:32z  Hi all, A recent post on AvSim suggested that considerable reduction in stutters in FS2002 could be achieved for those with a 128Mb graphics card by reducing the AGP Aperture value to a nominal value of 16Mb. This means editing your BIOS. I've seen this recommendation before when I had a 32Mb card and it made no difference to performance. However, with my GeForce4 Ti4600 there is a definite reduction in stutters. In fact, it's hard to detect any now! I can recommend this action. It's made a big difference on my system: - Athlon 2000XP 512Mb PC2100 RAM GeForce4 Ti4600 128Mb Iiyama Pro 454 19" CRT running at 1280*960*32. Windows XP Home.

RayProudfoot Certificates/Ratings/Crew Stations: 3. "RE: AGP Aperture setting with 128Mb cards" 08-21-02, 18:08z  Hi Frank, I feel another long thread starting <<What are these 'stutters' that you (and others) refer to? >> Surely you must remember the many discussions that took place on FS Forum (later Gamers) on the problem of less than fluid movement of the outside view commonly known as stutters? These are best seen by switching to a side-ways view and watching the ground scenery. It should pass by the aircraft without hesitation or any minor stop/starts. If you see any (and I'm afraid I did with the old AGP aperture setting) then it does reduce the realism effect. I don't know the technical reason why performance has been improved so much but to be honest I'm not bothered. If I can rid my system of the accursed stutters I'm more than happy.

I think VIA-chipset boards are prone to more set-up problems with AGP than others, but I don't know what the solution is. Maybe one of the "4in1" drivers VIA supply for such boards do the trick -- possibly also, when you update video drivers, some motherboard-oriented fix gets dislodged or disabled?

I hadn't appreciated it made an AGP card emulate a PCI one but as I said to Frank, I'm not really bothered as to what's happening inside the hardware if the end result is something I've been seeking for many years. <<If turning AGP off makes things better it sounds rather like there's a problem on the AGP setup, so perhaps some of those other BIOS settings, relating to AGP, should be looked at first? >> But why? I've not noticed any reduction in frame rates or anything else in Windows generally that would suggest this is not something that should be done. And what other AGP setting in the BIOS would you think should be looked at? To be honest, if I'm eliminating the stutters (and it is very obvious) then that's it as far as I'm concerned. I can appreciate that for some this isn't enough. They want to know the technical reasons but I'm not amongst them and I probably wouldn't understand it anyway All I can say is try it and if it works then fine. If it doesn't then by all means try other things but this solution will keep me happy. Regards, Ray Proudfoot, Cheshire, England Remove | Alert Edit | Reply | Reply With Quote | Top

I've not noticed any reduction in frame rates or anything else > in Windows generally that would suggest this is not something that > should be done. As you must recall way back, when we were discussing how to do a frame rate test which fairly compared the dynamic aspects of video cards and such (and we gave up), AGP really only comes into its own when exchanging large amounts of textures. The main effect of having a restricted channel for transferring the textures would probably not be frame rate reduction, but the late filling in of patches of textures in the landscape. Perhaps you will remember how noticeable that problem was on the photo-realistic textures such as the early ones by Andras Kozma, and the commercial ones for Pacific North West, San Diego, et cetera. The default texturing tends to use many copies of small textures, so the default exchange rate as you fly is small. When (if?) you obtain the photo-realistic scenery for England, the one being developed using the GetMapping photographic survey, then possibly you may regret that your AGP channel isn't being used? > And what other AGP setting in the BIOS would you think > should be looked at?

Of course in those days 32Mb was the norm so I suspect the rule book may need to be rewritten for 128Mb cards. I certainly do not now see the textures being redrawn as I fly along in dense scenery areas as I did in Sth California with the G400 and Viper 550 before that. In fact the G400 sped things up tremendously! <<When (if?) you obtain the photo-realistic scenery for England, the one being developed using the GetMapping photographic survey, then possibly you may regret that your AGP channel isn't being used? >> I'll look at it on your system first then decide.

In fact the G400 sped things up tremendously! Yes of course, but filling up that 128Mb means transferring data, and that's why faster AGP access can be important. There's no way the video card will know which textures you'll need next, FS has to find them and load them. Providing they aren't all changing too fast this is no problem. Remember when Sound Cards with large buffers started becoming available -- FS2000 (or was it FS98 then, can't remember) was more jerky and stuttery on systems with those sound cards simply because FS was downloading new sounds down into the card, in big lumps. They've fixed that, but it just shows that simply increasing the amount of buffer space doesn't necessarily help, it can make things worse -- it is good for repetitive stuff, but not for constant changes. > what you haven't said is whether you have tried this on your system. Yes, on my Win98SE Ti4400 PC, but no difference that I've seen. No noticeable stutters before and none after either. Maybe you'll see them -- you always saw stutters when I didn't in any case! <G> Regards, Pete -= VPC OffLine Reader Version 1.2 =- Registered to: Peter L.

I > hadn't appreciated it made an AGP card emulate a PCI one It seems Paul may well be correct about this only happening if you set the value *below* 16Mb -- I'm doubting my memory on this now (as you know it has been failing for a while now -- too much wine and beer, probably! <G>). It may be that this only occurs at 8Mb and below (reverting to PCI, that is, not losing your memory) , in which case you're still using AGP. I think it's a matter of suck-it-and-see.

PaulCroft Certificates/Ratings/Crew Stations: 6. "RE: AGP Aperture setting with 128Mb..." 08-21-02, 20:02z  Hi Pete When Ray got this old chestnut of a thread up and running once more I thought I'd re-acquaint myself with the details and see what was recommended now that graphics cards have moved on so much. I did a search for 'agp aperture' on Google and turned up a whole bunch of articles. The result appears to be that there's a whole bunch of differing advice on what the best setting might be. Some say half system ram, others have formulae based on system ram and graphics card ram. WRT your comment about <32MB aperture = no agp, it appears from the articles that the cut off point is 16MB and not 32. Even after reading all the articles I'm not sure that I'm really much the wiser. I checked mine when I saw Ray's original message and had a 32MB aperture set. I've since tried it with a 16MB aperture (I have a 64MB graphics card) and, fwiw, I can't see any appreciable difference. I suspect it's one of those things you have to suck and see. At least this is one bios setting you can tinker with without risking any damage. Paul Croft 10 miles SE of Heathrow (EGLL) -= VPC OffLine Reader Version 1.2 =- Registered to: Paul F.

You had to have a 128mb card for this to work. I suspect the guy who discovered this may well have had a 64Mb card previously and as he didn't make any recommendations WRT that card it seems it wouldn't have made any difference. But as you say, it's a simple change to see if it will work and if not then the original AGP aperture value can be reinstated. For the record mine was set to 64Mb - the default.

Vulcan Certificates/Ratings/Crew Stations: 22. "RE: AGP Aperture setting with 128Mb..." 08-24-02, 23:17z  I saw that thread too, along with many others on the same topic. One explanation of why the smaller AGP aperture and turning off AGP texture in DirectX worked was that modern video cards have sufficient on-board memory to completely load a scene. If you use AGP aperture & AGP texture acceleration that memory is set aside from main RAM and the contents are pulled from RAM and then onto the video card. The poster reckons that disabling these 2 settings means the video data is sent directly to the card so gets there faster and the larger video memory can handle all the textures for the scene. Someone did comment that running a video benchmark with the settings disabled gave a reduced score but the person suggesting the 'fix' stated that it was unique to FS and it did not affect frame rates as such, just got rid of the small stutters. However the number of threads on avsim about AGP aperture is huge and all end with 'well it worked for me' or YMMV. I do seem to remember when AGP was first introduced that a number of hardware sites said that it was a fudge and it did not do what it was supposed to do. -= VPC OffLine Reader Version 1.2 =- Registered to: Dave Wild -OLR.PL v1.76- Remove | Alert Edit | Reply | Reply With Quote | Top

I've since tried it with a 16MB aperture (I have a > 64MB graphics card) and, fwiw, I can't see any appreciable difference. It's almost impossible to "see" a difference unless you can set up a situation where the capacity of the data channel between the system and the graphics card is being tested. The only one I ever found was to stick the aircraft in the middle of a detailed photo-realistic scenery, like those for FS98 by Andras Kozma (Singapore being a good one for this), and, in slew mode, move the aircraft through it in a spiral patter, so that the textures had to be exchanged quickly. The effect then of a restricted channel is gaps in the landscape -- the more restricted, the more gaps. The frame rate hardly suffers at all, so it is not a good measure.

"RE: AGP Aperture setting with 128Mb..." 08-22-02, 00:12z  Hi again Paul, Forget my postulation that "16Mb" aperture was the minimum -- I just checked. At least on one of my PCs it goes down to 4Mb! I've tried setting it to both 16Mb and 8Mb, hoping to see whether DxDiag detected AGP getting disabled, but it doesn't. So I've no way of proving that 16Mb stops that operating. It's just something I remembered from all the stuff we were trying back in FS98/FS2000 days to fix stutters and things. Perhaps it was just "perceived wisdom" of the day and should be forgotten, or perhaps I remembered it wrong after all?

Snave Certificates/Ratings/Crew Stations: 23. "RE: AGP Aperture setting with 128Mb..." 08-27-02, 12:42z  Just throw my oar in here as a first post to this forum after a while spent `lurking`... Hi! to old friends! Nice to find a grown-up forum. We should distinguish between AGP Aperture and AGP Texture Acceleration. Both are switchable but they are NOT the same thing, although a by-product of reducing the Aperture setting is to switch OFF the Texture Acceleration this can only work on AGP settings that are accelerated to start with - in other words if the AGP Acceleration is set to 2x, 4x (or I s'pose 8x) in BIOS. This is often also known as `Turbo` mode. In VIA chipsets the same result can be achieved by reinstalling the chipset and going for the `normal` rather than `turbo` option. This precludes the need to make any changes to the AGP Texture Acceleration as the textures are un-accelerated. The size of the Aperture is almost irrelevant, if this is anything to go by: http://www.boogletech.com/modules.php?name=Sections&op=viewarticle&artid=2 As an AGP card occupies an active AGP port, you CANNOT switch AGP off without crashing the system and losing the card. It's quite important, I feel, that we distinguish clearly between switching AGP off and AGP Texture Acceleration. Simon Evans Remove | Alert Edit | Reply | Reply With Quote | Top

"RE: AGP Aperture setting with 128Mb..." 08-27-02, 18:30z  Greetings Simon: > Just throw my oar in here as a first post to this forum after a while > spent `lurking`... Hi! to old friends! Nice to find a grown-up forum. Welcome! If you can appreciate mature exchanges of ideas (some of us are not quite grown-up yet!), you might feel right at home here at the VPC. Thank you for pointing out the differences between AGP Aperture and AGP Texture Acceleration. From my experience, all I can gather is the optimum AGP aperture setting(s) depend on a number of factors which include system RAM, AGP card RAM, motherboard chipset, drivers (motherboard and vid card), the scenery you're running, and even your OS. Like most things with PC's, hardware and software diversity is a strong point, but also a weakness for the platform in cases such as this where there are almost endless combinations. The only real answer for some of this stuff is just to try it and see if it works better. While it may seem like a PITA to some folks, for me tinkering is part of the fun (well, as long as it's not Java related!).

Snave Certificates/Ratings/Crew Stations: 27. "RE: AGP Aperture setting with 128Mb..." 08-27-02, 20:41z  Yes, I have read some extremely duff advice. Obviously they mean well, but they don't have the merest inkling what they're talking about, nor can they be bothered to find out...! I'm no expert, but if I see something like that posted, I will probably not only try it for myself, ('coz I like to live dangerously), but also research WHY it should work - hence the link I posted earlier. Spent a couple of days wondering why my ancient system locks up when I try that tweak (yes, you guessed it, my Biostar Mobo is only operating at AGP 1x anyway...) BTW, much the same effect can be achieved by fiddling with the read-ahead frames facility in most graphic card control panels. On my GF3 Ti200 and many other Nvidia cards it always defaults to 3, which is a ludicrous number. Just start at 1 and work up to 10 or more (if your system is sufficiently powerful) and you may find a pleasant surprise awaiting if you s-s-s-u-u-ffer from the st-st-stutters... Just remember that after making the tweak it's a good idea to reintroduce the card to the sim via the .cfg file replacement I referred to elsewhere.

I have the same card and have left it at the default 3, will try the 'creep-up-on-it approach' and see where I get I will also try the .cfg file 'tweak'. -= VPC OffLine Reader Version 1.2 =- Registered to: Dave Wild -OLR.PL v1.76- Remove | Alert Edit | Reply | Reply With Quote | Top
