can you please tell me why:
radeon:


nvidia:



under http://www.eartcontrol.de/downloads/molifax/molifax2.rar you find the fx-files included which can be reloaded to the demo using middle_mouse press and u/i/k - keys...

i hate this sh*t

Ello, youre not the only one with these problems that drive a person mad. Is this an A6 rendering problem? I hope Conitec realizes that publishers like a fair degree of compatability with their products. I'm not directly placing the blame on Conitec, but it seems like there is many re-occuring problems with shader code and different GPU's and I am running out of options quickly.

Interesting, i have not found any differnce in shaders between my radeon 9700 and my geforce 6800.. I cant imagine that if there is a difference its related to the aknex renderer..more likely you are using certain functions that are implemented differently in different hardware or drivers. You should contact Nvidia or Ati, maybe they can help you sort it out.

Are you required to have a different version of your shader for every GPU out there? Well, that may have been a little over-the-top but I have had major differences with tests done between a Radeon 9200 and a Radeon 9800, both using the same shader code. Many other users have posted other differences between GPU's as well, this isn't an isolated incident(I cannot confirm what others have said in the past to be true however but do not doubt it).

matt, can you check the fx-files which come with my bug-demo?

Not only the shader version, but also the number of shader registers can be different between Radeon and GeForce. I suggest to check the number of registers. That's the only possible reason that I could think of. The engine does not contain a 'won't work with nVidia' flag.

ah.. so i think if i want to create shaders seriously i'll have to buy me a nvidiaCard as well. oky. which one is the current state of the art ?? something like 6800??

hi,

GeForce 6800 Ultra, 6800 GT, 6800 are in the moment nVidias highend Cards, and
GeForce 6600 GT, GeForce 6600 are the new mainstream products. There is also
a GeForce 6200 Cards, but i think one of the first is for shadertesting the
best choice.

Frank.

Could this be to much different speed/quality switches in the driver???
Geforce looks rasterized in 8bit.

Hiya.

I recently bought a new computer, video card as well. After a weeks of searching, compareing, asking around, etc., I found that the GeForce 6800 GT is your best bang for your buck. The 6800 Ultra's are WAAAAY to expensive for the performance boost you *might* get (generally, all the tests I saw put an Ultra between 0 and 7 FPS faster than the GT...might make a difference if we were talking "33 FPS" vs "26 FPS", but not noticable when dealing with "101 FPS" vs. "108 FPS". Not for an increase in price of several hundred dollars.

From what I hear, the Radeon's are better at D3D, and the GeForce are better at OpenGL (IIRC).
