doesn�t work at all, neither on my x800xtpe nor on my 6800ultra.

using cat 4.8 (even tried 4.9beta) and the newest nv drivers up to 66.00.

dx9c is installed to...

i alway get something like "couldn�t initialize 3d3......bla".

but all my games and apps work perfectly, far cry even confirming in console that instancing IS supportet (on both cards)

any ideas?

Hey Humus,

Very nice work.

Running an ATi Radeon 9500 Pro here, DirectX 9.0c and Catalyst 4.8 drivers. When I tried the "each particle draw per call" option, my frame-rate slowed down to 10-30FPS. Instancing, 150-300FPS, Using the Vertex Shader Constant Instancing method, 100-150FPS. And the buffer method, 60-90FPS.

Impressive use of the Instancing / Vertex Shader 2.0 specification techniques and [volumetric?] particle effects, keep up the great work man! ;-)

Why don't you all shut the crap with instancing does not work blaaaah. I think people come to this conclusion since none of you have ever coded a real 3D application and not just a fancy looking effect or demo. One of the most often found bottlenecks is the batching of draw calls (of course they are CPU dependent since they go through system->API->driver->card). Instancing can exactly help to reduce this batching crap.

Humus, your conclusions seem to be true. I've a 6800GT, default clocks, and I get completely different numbers than everybody else with metho 2 yielding highest fps, thus we are limited by CPU, memory, whatever, which directly leads to the conclusion, that instancing can't matter too much in the whole picture. Anyway, love your work!

BetrayerX,
it doesn't fluctuate much for me. It's within +/- 5-10 fps or so, which isn't much when we're talking about 400fps. Good enough to get a sense of it. The problem though is that the first three methods are all quite fast, so they all are very CPU dependent. I get only a little better performance at home (X800pro) than at work (Mobility 9700), so it's not very useful anyway to compare between cards.

Jecht,
yes, it should work.

a really nice upgrade for all of your demos would be a benchmarking utility

cause all of the demos are really good looking and have nice technics

This demo works with Cat 4.9b, right?
