DirectX 9 Shader optimisations?

[Skeee]

Actually, just to clear up the mis-guiding subject of my post..

I'm looking for max options settings, or graphics card driver settings, that will
help increase the performance of the real-time view of DirectX9 Shaders.

(not fx file optermisations).

Skeee!

strange this kind of shaders run very fast on my pc without relevant difference in performance i have a poor 9600 ati.isn't a gpu power problem this is sure.
sayed and resayed words... get the latest driver.
how many is the performance reduced?
what can i say?!? take a plugin or max 8 and try your normal map in render.

Thanks for the reply..

How noticable? - well standard materials will allow realtime perspective view rotation over 60fps. DirectX9 materials - well below 10 fps (ie. it's VERY noticable)

If I have several directX materials in a multisub, applied to various objects in a scene you
will see each object be drawn one after another, after another - it's that _slow_ ! :/

I am using Max 8 - latest drivers already.

Any further ideas, anyone?

When I've done tests with the directx display of standard materials I've found that it's fine drawing one, but I get significant slow down with more than one active at a time. Something like ten times slower with a second one active. The viewport navigation lags behind the mouse movement. This is with an ATI Radeon 9600. Not very recent drivers admittedly. I found newer drivers just caused more problems so I had to roll back.

I tend to just use standard materials when working and only replace them with real time shaders for testing purposes. I put it down to automatically built shaders being highly unoptimised compared to custom written ones.

I get fast DX 9 displays with my FX 5200 :shrug:
