Something to bring your Radeon 9700 to it's knees.

[Humus]

Yup, my latest demo does that, almost. Simple scene + complex lighting = around 50fps in 1024x768.
What I have done it to evaluate the phong illumination model in a fragment_program, replacing things like normalizing cubemaps with math.

Wow did it EVER bring my 9700 Pro to its knees:

"Your driver doesn't support GL_ARB_fragment program. This demo will now exit."

I'm using the current 6193 drivers on Windows XP, btw.

 

[Humus]

You need to very latest 6200 drivers.

Imagine how hard it would have been if, instead of mistakenly using his 'given' name 'Phong', they had correctly used his family name, Bui-Tuong.

I should use the latest 6200 drivers? You should have mentioned that when you first mentioned your demo.

Unfortunately, though Rage3d does have a link to them, here's also what they wrote:

"This driver is an internal leak and hasn't been to successful on some systems. I wouldn't recommend using them as they break some features. I have word that the official 7.79 set will be released soon!"

 

[mech]

"its" even.

Yeah, I forgot.
I had some problems with the 6200 at first, it didn't work when using two monitors. When I disable the secondary display it works just fine though. If you're using a single monitor I think it's pretty safe to use it.

Worked great for me, even with dual displays enabled, using the 6200 driver set

with 2X AA and 16X AF on I got around 35 FPS while just sitting there watching the lights

9700 Pro

looked pretty sweet! very sexy...

I'm running the 7.79 driver from the ATI developer site. (6.13.10.6200)

It still complains about GL_ARB_fragment_program.

Is the leaked driver newer than that?

Wow, fantastic demo. Hovers at 60 fps on my system, 4*AA, 16*AF.

Weird thing is that GLInfo doesn't report ARB_fragment_program being available on the 6200s. Not that I'm worried mind you.

 

[Nick[FM]]

Nice work indeed! The tiles (dunno if that's the correct word) look really real!

Now do add some shadows into that "bathroom" and voilá!

Worked fine with my R9700 & 6200 drivers...

The leaked driver has OpenGL version 1.13.3413, while I think the developer driver has 1.13.3410.

Well, GLInfo is right. It's not exposed. However, it's still fully functional as far as I can tell. I suppose it not exposed yet because of some issue I don't know about or maybe it just isn't tested enough yet. I did a dirty hack to allow this driver to be accepted anyway. I first check for GL_ARB_fragment_program in the extension string. If it's not there I check if the vendor string is "ATI Technologies Inc.", and if so then if the version string is 1.13.3413 or higher it sets GL_ARB_fragment_program = true. I'll remove that hack once a driver properly exposes the extension.

Hmm I can't play that demo, its r300+ only

It's weird... it works here...

Cool program.

A quick look through the shader shows that you used a bunch of multipliers for the specular. You could of used the log/exp functions instead -- 3 instructions instead of 7 or 8.

Just a quick note.

 

[Himself]

Looks nice, kinda boring. It did take my system down on exit though, dunno if that's what you were referring to by bringing the card to it's knees. The number 22 was in the top left corner at 1600x1200x32.

You should really do up an OpenGL benchmark out of this stuff. Do as good a job as madonion and you might even make some money off of it.

Yeah, I know. I figured exp and log would be noticeably slower, and I didn't need a perpixel exponent anyway, but I didn't test though. Might aswell do that.

 

[Humus]

Alright, changed to EX2/LG2 for power and it turns out to be faster. I was also informed that what I had done was actually closer to Blinn illumination. So now I have updated the app to support both blinn and phong, just type "blinn" or "phong" on the console and it'll switch shader. Fixed a problem with ambient too.

Nice one Humus!
