ok new dilema, if I installed a new graphics card, could that possibly have slowed up my rtcw. I do believe the new graphics card is better than the old. I would appreciate any help on the subject.

Hi,

Sounds like a graphics driver problem to me. Did you replace an Nvidia card with later model (ie: Geforce2 with a Geforce3) if you did get the latest drivers for your card from Nvidia, the older drivers that oroginally came with your card will seem to work fine but new drivers will give improvement. Other things to check are anti-aliasing (off for faster, though I use 2X on mine - your new card may be set to use anti-aliasing by default whereas your old one would not) If it's not an Nvidia card check manufacturers site for latest drivers. Also check bios to make sure that it is running in 4XAGP and has AGP Aperture set to correct size (usually 128 with new model cards).

That's about all for now, let me know how you go

We have been doing some experimenting to see what settings in the BIOS affect benchmarking scores the best.

I've been told that you set your agp aperature size to HALF of your system RAM size. I am running 512 mb DDR so I set my aperature to 128.

After sitting through countless 3dmark2001 runs, we found some interesting settings. The 4x setting is a must. Setting it lower degrades the benchmark score. (no brainer there) We then started LOWERING the aperature size from 256, to 128, to 64, to 32, to 16. We found that the BEST benchmark was achieved using a 32 mb aperature size. In fact, when running with this size, MUCH more detail appeared during the benchmarking. (rocks kicked up from the 4x4, sparks from the bullets impacting in "lobby", etc. )

Give a smaller aperature size a try and see if it works for you too. Too small and it gets very bad.. so find the perfect setting.

Curious, I was just passing through and caught your suggestion with apeture. I wasnt quite sure but assumed the 512ddr is the 845 chipset or Via chipset ddr sdram? I have a 128ddr vid card and currently running 64 apeture but can choose 32. do you recommend 32 in this case? just to clarify the attempt. I would like to try. I benchmark 6568 with Pentium III right now which I dont think is too shabby, but I also havent benchmarked since the new drivers released that tout substantial higher scores. I do know this. set all to performance versus quality, uncheck wait for vertical sync and you will benchmark slightly better.

Hi all,

Just a point about AGP aperture to clarify things a bit. The AGP aperture size is an area of system memory that's put aside for use by the video card "IF" the available memory on the video card is exceeded by the amount of memory required by the current program. In 3D games most of the memory is used by textures, but even so rarely will you need more than 64Mb of video ram for storing 3D data.

It made sense in the old days when video ram was expensive and some 3D video cards had only 16Mb (or even 8 Mb :mad: of video ram) to set aside as much system memory as possible for use by the video card in case the latest and greatest game ran out of video memory. However with many video cards now having 64 and 128Mb video memory it seems wildly over cautious to set aside half of you system ram for the AGP aperture, especially when 256Mb system ram is now a basic requirement for most (read all) PC systems. Setting aside a lot of memory for your agp aperture, as experienced by FlederMaus! can slow the system down because of the overhead of handling the extra memory. 32Mb should be plenty for a vid card with 128Mb ram and 64 for one with 64Mb. I wouldn't go under 128Mb total memory adding card memory and AGP aperture memory topgether.

The bottom line is of course to fly it around and see if it crashes.

Hey kid thx I had agd ap set at 256, just changed it to 64 to match teh v-card and so far seems smoother. But what about PCI Latency? My Basic Sys: MSI K7T266 Pro 2 AMD XP 1700 @ 1467 MHz 1.536 GB DDR PC2100 nVidia GF3 Ti200 64 DDR Any Advice? Some Current Settings... Anistropic? Disabled AntiAliasing? Allow Apps PCI Textures? 256MB wolfy.gif

Hi all,

Anistropic? Disabled

The anisotropy is the ratio of the long side of the rectangle to the short side:

Anisotropy = MajorSquared/Area = (L x L) / (L x S sin q)

= L / (S sin q)

The short side of the rectangle produces the level of detail for the MIP map:

Minor = Area x InverseMajor = (L x S sin q) x (1/L)

= S sin q

Get all that?

Now to simplify. You know in games when you get further away you see less detail, and in Serious Sam you can even see lines where the detail suddenly drops off? Well anisotropic filtering will smooth out the sudden changes in texture to make to scene seem more real as you move towards it and away. If you have enough grunt turn it on.

AntiAliasing? Allow Apps

Will be turned on or off by apps if they think you have enough grunt. Having anti-ailiasing on will drop framerates by 4 for each level ie: 2 X antialiasing, 1/4 framerates, except if your card supports anti-aliasing in hardware - check your specs. This feature smooths out lines that are at an angle to the vertical - reduces jaggies in other words. That said it can only reduce jaggies to the limit of your screen dsiplay. If you are running a 21" Monitor in 2048X1920 or some such stupidly high res anti-alaising will not make the slightest visual difference.

PCI Textures? 256MB (I assume you mean in the settings for the video card) Try lowest setting for this - but it doesn't matter how you set it in theory cause it will only be active IF you are using a PCI video card - and who uses PCI today?

PCI latency timers are a mechanism for PCI bus-mastering devices to share the PCI bus fairly. You can get utilities that let you adjust the latency for your AGP card, but if you give too much to that you will find slowdowns in other devices ie: modems, lan cards etc. If you are playing rtcw over modem you probably shouldn't fiddle with this as it will slow down your connection.

hope this helps

apocalypse_kid Sounds like he definitely knows his stuff.

My system is an AMP 1900+ and my experimenting involved using a Geforce 3 ti 200 card. I've got an Abit KR7a Raid Mobo that has a lot of confusing bios stuff that can be tweaked out quite a bit.

Make sure you have the latest Nvidia drivers first of all.

Anyway, I just bit the bullet and got a Geforce 4 4600 card off ebay, paid $275 for it and it is a great card. However, I also ran a Geforce 4 4200 with 128 ddr for a week and that card was only $200 at Walmart. This card is my nephew's but he let me try it out for a bit on my system. Anyway, if I did it again, I'd just get the 4200 card as it is almost indestinguishable from the 4600 in performance. My old GF 3 performs great, but there are some improvements in video performance with the newer cards.

Download 3dmark2001 and use that to see how your system reacts to various bios adjustments. Keep a simple log of what you did, how it scored, etc. It is a painstaking process to hone in the best performance without overheating, crashing etc, but it definitely a good way to learn what different settings will do for you. Take it one step at a time and see if you can up your score to it's max.

There is a pretty good Nvidia tweaking program called Riva Tuner that will let you overclock your videocard and you can really crank up the performance using that too. As with any o/c-ing, you just have to use caution.

I am still learning a lot about my system, but I haven't "let the smoke out" of any of my components yet... (once you let the smoke out.....it's all over with! bad technician humor )
