Other Drivers like KX Drivers (for other hardware)

Chester01 · Oct 22, 2004, 09:46 AM

Does anyone know of any OTHER drivers which are similar in funtionality to the KX drivers but for other hardware? I mean drivers that are user created here, possibly for Nvidia cards or something along those lines. I am not talking about the Omega drivers here, which are mostly pre-moded nvidia drivers (not that I dislike the Omegas) but think about the performance you could get out of the Nvidia cards if you could custom configure their DSP's or whatever they use?!

there was something ragarding using opengl drivers to turn the nvidia/ati gpu into a DSP

WTF?!?

dj, any links?!?

Well, I don't know of any other drivers like Kx, but for ATI cards you use Rage3D Tweak (www.rage3d.com) to tweak lots of settings (although not as powerful as direct dsp access)...

dj_stick, you remember that driver you were talking about? It may be worth looking into....

**dj_stick** · Oct 23, 2004, 05:51 PM

sorry i don't remember much about it, search the forum for it - i think there was a link at one stage

was it under the kx fourm or the entire driverheaven fourm?

**dj_stick** · Oct 23, 2004, 08:18 PM

kX i think

to someone with some dsp + opengl programming knowledge:

so far thats all ive found related to creating a dsp for graphics cards (Has a link in it)

You should know that GPUs are not DSPs, they are more like standart CPUs, but oriented towards graphics. Brook is not a driver, but an extension to ANSI C, that allows parallel data streaming to both the CPU and GPU and the use of the GPU for standart operations - in other words it does not transform it into a DSP, afaik.

so could i use my gpu as a cpu? or would any software i run need to be re-coded to use the gpu instructions specifically? (almost like having dual processors?)

EDIT: I found this link; it talks about this somewhat

now we just need Eugene to learn graphics processing lol

I know that this may all sound quite stupid to many of you, but here is how i see it: If it were possible to "transform" sound samples into "images" we could then on the GPU apply some sort of transformation to that image then convert it back to a sound. it could be done in 32 bit theoretically too, 32 bit color SO each pixel in an image could be a 32 bit sample of sound. I hope i explained what im thinking fairly well and probably from a programing point of view it sounds like a pain in the ass but it would be cool if it can be done.

http://www.visualprosthesis.com/javoice.htm <-converts greyscale image to sound

GPU Reverb/effects
1.Sample sound into an image, 32bit sound ->32bit color
2.Send "image" to graphics card to be transformed: if you wanted an echo effect, you could take one sample and move it down 100 millisecconds but transform it to lower the "volume" by 25% or something like that so you would not get a feedback loop.
3.Once the transformation is applied, read the transformed image from the graphics card back to the computer, the CPU or the sound card would understand the image to be sound information (which it really is) and output the sound to speakers.

^this is the meathod i think may work. If possible we could have quite complex dsp effects.

http://www.bionicfx.com/ (DAMMIT!!!!!!!!! (its been thought of before)

it sitll would be cool to do within KX tho

a very cool way of looking at reverb effects:

afaik the biggest problem with all that is downstreaming the processed data from the graphics card's memory, since the agp wasnt designed with that direction of data in mind.

Chester01 · Oct 24, 2004, 01:44 PM

ive noticed that too (as being the major problem) people have achieved 32 ms latency though (16ms of that is going back from the graphics card to the rest of the computer)
