Is Direct3D suppose to be THIS slower than OpenGL?

Hi ,I am not sure where to post this.. I might be having a serious problem in which none of my games that uses Direct3D would perform well on my computer. Before I explain my problem here are my computer's specs:

AMD Althlon XP 2000+
Geforce3 Ti 500
512 DDR Ram
Nforce Asus Ultra Mainboard
Windows XP Pro

I have all the latest drivers for every single components in my computer. I am up to date with Direct X 8.1

Here's my problem.. Any games using Direct3D at no matter what video settings will run at low frame rate. My frame rate when playing any Direct3D games will just be extremely unstable. I usually use 1024X786 resolution. I get an average of 20 - 40 frames per second or lower on ANY games using Direct3D. And I would usually get a lot of slow downs in the frame rate. I get slow downs when like I am looking at sceneries that has a lot of stuff. I especially get slow downs during a lot of action in the game such as shooting , explosion ect. My frame rate would usually drop to around 5 - 15 fps when there is a lot of shooting in ANY games using Direct3D. While games using Open GL like Quake3 would maintain a high frame rate of about 150 fps at highest settings, even when there's a lot of things and action going on in the game.

I play games like Deus Ex, Giants : Citizens Kabuto, Operation Flashpoint, or Morrowind. Now my question is , is this normal? Is anyone else experiencing this "problem"? Are Direct3D games suppose to be THIS slow , that the games are almost unplayable? If so why is it that most games uses Direct3D?
Please help me out here... Thank you.

ive had alot of problems in the past with directx 8.1

i suggest you stick with 8.0a
problems like yours too, extreeme slowness in direct3d games.
could also try updating to the latest detonator drivers.

Yes, however with me it lags with EVERY SINGLE game. That I have tested. I understand that Morrowind might be slower than other games however, many people said that they were getting much higher frames than me , even people with system specs 3X as slow as mine.

Giants is Direct3D I have checked it about 10x to make sure that I was not wrong. No I do not believe it's XP again , because many people with Win XP claims that it makes their games run quite faster. And for Operation flash point , many people told me that the game runs smoothly for them , even though many of them had computer specs than are much slower than mine.

I have checked my BIOs settings and they are all in the correct settings. BTW this is my 2nd mother board , for I have replaced both my motherboard and video card and got no luck in doing so.

How Do I degrade it to Direct X 8.0a? Whenever I reformat the computer it will just automaticly install DirectX 8.1.

I Do have all the latest drivers for every single components on my computer. I forgot to mention , there is also one odd thing about my problem , when I ran it with 3Dmark2001 SE it gave me an ok score of 8300. However when it comes to gaming it just runs like crap.

As you can see Fil , like many others is telling me that they run games such as Operation Flashpoint without a problem , even though he has a video card that's about 4X as slow as mine! Also , his processor is a little slower than mine , and I notice him mentioning that he has 2X FSAA on while I have it on the off option and it still runs like slower than a turtle without legs.

I have tried turning every single settings to the lowest texture/resolution and the game still runs extremely slow , only giving me a small boost in frame rate.


P.S. This is a relexation forums?? I didn't know that , but since it says "other" , and since this forum doesn't have one for technical support , I thought it might have been appropriate to post it here. I'll try to move my topic to some where else if possible.

Not true. OGL is a bit more accurate and takes more time to render (thus renders slower). What r ur drivers?

My frog asked me for a straw...dunno what happened his ass all over the place

I asume that you have set your AGP aperture size to 128MB inside your BIOS.

Go to the Graphics Driver setting and checj the following:
Under the Direct3D tab:
Check if the Texture memory (or however it is called in English) is set to atleast 128MB.
Then go to the More Direct3D tab and check if V-sync is set to off.

This might help fix your performance problems.
