New instancing demo

[Lezmaka]

Approximate performance numbers on my system:
1 - 400fps
2 - 365fps
3 - 330fps
4 - 120fps
5 - 55fps

Approximate numbers on my system (Athlon XP 2000+, GeForce 6800):
1 - 202 fps
2 - 186 fps
3 - 207 fps
4 - 87 fps
5 - 38 fps

Hmm.. Interesting.
On my system the number is somewhat different.

P4 2.1Ghz, GeForce 6800 GT
Win XP sp2, DX 9.0c , 61.77 NV driver

1 - 172 fps
2 - 225 fps
3 - 176 fps
4 - 80 fps
5 - 47 fps

VS 2.0 path (#2) seems best on my system.
Any guess ?

Athlon XP 3200+ and 6800GT @ 420/1100 w/DX9.0c, 61.76 and SM3 enabled as far as I can tell with SM3 enabled.

1 - 275
2 - 275
3 - 350
4 - 120
5 - 75

On Chalnoths system, option 1 is faster than option 2. On ysoya's system, option 2 is faster than option 1. And on mine, they are the same speed.

Edit: Just tried it at stock speeds, 350/1000
1 - 267
2 - 274
3 - 350
4 - 122
5 - 78

Does the source code back up your statement or are you shooting from the hip?

I don't think he's shooting from the hip, rather somewhere pretty close to the hip.

 

[KimB]

you think the cpu makes a big difference?

Maybe.

And with respect to the other poster with a 6800 GT, it might be the drivers. This early-on, different drivers are bound to produce different results. I'm currently using the 65.62 drivers.

I'm assuming that's on the system in your sig?

Please don't feed the troll. Just wait for the orderly to take Ruiner back to his padded cell and then everything will be nice and quiet again.

I cant get it to run for some reason. Im on a 6800gt dx9.0c (most of the files in dxdiag end with 2126) and the 61.77 drivers. The error is couldnt initalise direct3d. Make sure directx is installed. Im using the exe from the zip

ATI demo don't work right on Nvidia cards... Surprise!

Surprise! Maybe Nvidia's implementation of SM3.0 instancing isn't as good as we originally thought now we have another implementation of instancing to test it against?

 

[Baraclese]

The application quits at startup with an invalid instruction.. I guess that must be my old thunderbird@800MHz

 

[Drak]

Performance on my rig (P4 3.0GHZ + GF6800U at stock 61.77)

1:348
2:385
3:367
4:178
5:84

At high framerates (300+), the fps counter changes too fast. Can you make a version with a moving window average please Humus?

ATI demo

Did you download this from ati.com?

don't work right on Nvidia cards... Surprise!

mode

x800
fastest - 1-2-3-4-5 - slowest

6800
fastest - 2-3-1-4-5 - slowest

The 1-2-3-4-5 order does not indicate any sorting by speed. If another card has other performance characteristics that doesn't mean something's wrong. Yes, 5 should be slowest, and 4 better. The first three however are all a good deal depending on CPU speed. Neither of them are expected to always be faster than any other. Depending on a bunch factors in real world applications, any of them may come out as fastest.

Optimized for official dx9 spec Geometry Instancing under SM3.0? Nope.

Optimized for ATI cards and their brand of instancing? Yep.

Since when does the spec say anything about performance?

Ah crap, I forgot to skip past loading the vs2.0 shader for those cards. I'll fix that later tonight. Gotta go to work now.

I didn't know Humus coded his demo to use a vertex frequency stream divider.

Exactly. This demo probably doesn't use NV40's GI at all.

How does the NV40 do GI ?

[edit]

Doh! Don't answer that - I just scrolled up a bit from the link I posted below and read the HLSL_Instancing

 

[pocketmoon66]

Sweet! I can't wait 'till OpenGL gets a spec for instancing.

Well here's one way to do it. 20million/second.

I run WinXP SP2 RTM and most of the files end with 2180 in dxdiag.

Some approximated results:

Cool demo, humus.

dunno how that is

Well Ati and Nv are not doing it the same way, Ati is using a trick AFAIR
