Help with my very first shader program
category: general [glöplog]
I've just done my very first pixel shader program.
It is DX9, shader model 3.
My graphics card is a very very shitty one, and the speed of the code is about 3-4 times slower than in my dual core CPU rendering.
So, could you try the code in your computers and tell me the framerate and the card you used? This would help me to see if it is worth to invest in a graphic card and wich one to choose.
The code is here: http://www.romancortes.com/ficheros/shader.zip
Thanks so much

Oh, my framerate is 25 to 50 fps in a ATI X1650
nvidia geforce gt 130m
332 - 700 fps
332 - 700 fps
geForce 8800 GT , from ~550 to ~700 fps
good luck!
good luck!
Ati 4870 x2
793-1256 fps
793-1256 fps
nvidia 6600GT
28fps - 96fps
28fps - 96fps
8600m GS, I get an error: "fallo"
1200-2000 fps, nvidia gts250
Thanks so much, I have enough data. I think I'm going to buy a gts250, it is cheap and there is stock near my house... and it looks very fast by the Premium data.
Iq: it says "fallo" if the pixel shader can not be compiled... the why not in your card, I have no idea... I might send you the source, that is based in your framework, so you can tell me what I did wrong...

if the pixel shader doesn't compile the bug is in the shader, not in the framework I guess. I bet on my drivers...
radeon hd 4870
1000 -> 1800 fps
1000 -> 1800 fps
1276-2645 on ATI 4850(9.5 drivers, so not the latest)...and this is on my bogged down test XP installation and not my barebones fast demo/games one...you other ATI guys must have some serious bloated crap running in the background on yours ;p
900-1200 fps. geforce 8800 GTX
"fallo" on a ATI 4870 XP SP3.
400-900 ATI HD4650
~300fps Nvidia Quadro FX 580
~1350 - 1800 fps on a nvidia GTX 285.
121 - 360fps on 9600gs m (win7 x64).
erm... 8600 of course :)
Newest drivers and DX runtime did the trick.
I get around 1300 - 3000 FPS.
ATI 4870 HD & XP SP3.
I get around 1300 - 3000 FPS.
ATI 4870 HD & XP SP3.
1000-1500 fps, gtx260, xp32
240 fps on HD 2600 XT

d3dx9_42.dll already ?
dumb question then: can i just upgrade the SDK somehow or do i have to completely reinstall a whole package ?
dont want to just download/copy any .dll downloaded wherever, even if its "safe" !
oh, nevermind, having newest SDK is best solution anyway, so imma just download the package and install now !

hmmm strange that the gtx 285 shows lower framerate than the slower gts250..... me uses win7 64bit, intel c2d e8400 @3ghz 4gb ram
