3D Mark 2k Skipped Enviromental Bump Mapping. Why?

[paruhd0x]

You can look at my system specs at the below link in my sig.

Does anyone know why it skipped it? It said my hardware doesn't support it but I don't beleive that...

 

[illbot]

do you have matrox g400

No. I have this:

Asus v7700 Pure (Nvidia Geforce 2 GTS)

Unless you have the Matrox or the Radeon...........

Radeon does not support DX6 bumpenv (real name for technique G400 and Radeon uses).

You shouldn't worry too much about it though....DOT3 and Cubic is what developers are concentrating on.

The GTS not supporting it could cause it so say that

&quot;DOT3 and Cubic is what developers are concentrating on&quot;

really? name any main-stream games that use it?

I think EMBM is more feasable, once Nvidia adopts it as well in their next release.

Leon, I have a Radeon and 3dmark 2k does the enviromental bump map test-acually looks pretty cool! Unless I missunderstood your post.

 

[Leon]

I am not talking about coolness factor. I have G400Max and know exactly how the technique work.

It's a hack, plain a simple, if you consider the math behind it. There is simply too much approximations.

nVidia have a few demos of real, TRUE Environmental Bumpmapping (not DX6 bumpenv) on their site. Unfortunately, it's emulated in software, and really slow (reading back from framebuffer).

However, effect will be possible with pixel shaders and DX8 compatible hardware.

Sorry-I guess I didnt understand your 1st post-It seemed like you were saying that the Radeon wont do the EBM test-it doesnt support it. What you really meant to say was that the Radeon actually doesnt do &quot;TRUE&quot; EBM as you explained in your 2nd post. Thanks for the clarification.

paruhd0x,don`t worry about it also skips the test on my own Geforce2 MX,I think the Geforce cards don`t support that type of Bump mapping.

 

[JayPatel]

mems right....geforce cards..actually all nvidia cards dont have the hardware support to run that type of bumpmapping....and i woudlnt look for it to be ever supported by nvidia... i think cubic environment mapping and per pixelshading looks a lot more better.

No hardware today are capable of full pixel shader support. GeForce family can do &quot;some&quot; per-pixel shading effects by using register combiners in OGL.

EvilDonnyboy, yesterday I just installed a game supporting Cubic. It is Colin McRAE Rally 2. Pretty as hell but it eats framerate for breakfast even on a GF2 Ultra.

 

[Leon]

Just a little reminder-Radeon supports Cubic, DOT3, and DX6 bumpenv in hardware - all three.

From what I read in ATI SDK, they aslo have OGL extension similar to Nvidia combiners, but less powerful.

[Leon]

Speaking of cubic, while it's certainly a nifty feature, it won't be used for a while. It gobbles a lot of fillrate, and have limited use.

DOT3, on the other hand, will be extremely popular in the next few years. Cannot wait fully bumpmapped DoomIII

[ahfung]

Now I'm so confused, how about Per-Pixel shader of GeForce? Does it relate to mappings?

 

[Leon]

DX8 Pixel Shaders is basically next generation of multitexturing. While no hardware supports it, GeForce family can do some of the effects using Nv_register_combiners.

How does this relate to bumpmapping? Well, you can do several DOT3 operations at once (A dot B and C dot D in both combiner stages), greatly improving performance

ah darn I wanted to get it to work so I can rank up more points

 

[Taz4158]

Well you wouldn't get any extra points since it's not used for the result.
3DMark Overall Score

3DMark Overall score is calculated by summing up the result of both game tests and all of their detail levels multiplied by twelve. The formula is as follows:

OverallScore = (Game1LowFPS + Game1MediumFPS + Game1HighFPS + Game2LowFPS + Game2MediumFPS + Game2HighFPS) * 12

The unit for 3DMark Overall Score is '3D mark'.

 

[Deeko]

Oh man, you just said a Bad Thing in Deeko's mind You said you wanted to rank up more points in 3DMark. Ouch 3Dmark is the worst benchmark ever. DO NOT worry about your score in any way.
