What are Pixelshaders?

Anyone have a screenshot of a in-game, showing the same PC running DX10 and DX 9 taken from the exact same spot and settings etc?
I'm very interested to see if Crysis or any FPS is intensely better on the same exact PC just different DX levels.

Even though the thread may have started awhile back it helped me understand things better. All the stickies help tons. Thanks Toms and the authors.
 


A pixel is one of those cute critters that comes out in the night to cavort and romp through your data...

A pixel shader is the wee umbrella that they use to keep from getting moon burnt...

all kidding aside, the OP made an excellent post. Once I've finished digesting it I may have questions.
 
You know, now with the introduction of MS Vista's Direct X 10, I feel a great deal of us are going to fall into the originally aforementioned slump. Yes, buying the biggest and baddest vid cards just to stay on the money! or out of money...


At any rate...some games will start to require it soon enough, if not already, and I look forward to the change...


Next step; raise 300 bucks for my new vid card... -sweat drops-
 
Nice post..

about DX10. I've seen fantastic screen shots of Flight Simulator X showing of DX10 rendering oceans with much detail. Bu when I installed FSX to a fast computer running DX10 and a brand new graphics card, the oceans didn't look special or different. Hopefully we can eventually see more dx10 optimizations that just a rare few in the near future. I know they also have many new lighting functions, better shaders etc, but I've still not seen much.
 
There is a hoax about directx, I am sure I have yelled at this very four year old thread. I recently blew out vid card #7 with my new mpeg2 camera....my card is supposed to render mpeg2, but maybe it does not understand my little standard size vid being 10mbit, anyway, whatever the Software breaking Hardware reason...
I can't help but wonder, if fixed pipeline (dx9 and older) had not fixed pipeline (dx10), would my card just give me the green vid of choking, rather than destroy itself....Hmmmm.
In other words, more than once, much more than once over my years with this "over hyped" seeming yearly event about DX upgrades, real video, beyond gaming, utilizes directx. It is NOT just for gaming, it is for the cards and machine and videos and os and colors and monitors and ALL encoding and decoding. To say you are caught up in hype about directx , there is other reasons aside from beautiful gaming that demand the cards that gain transistors with the gain of directx. dx10 is soon out, and so is 390million transistor cards for agp capable (ie: ati 2600 pro vs my blown 9550se with 50million).
I learned the bad way for my 10th year with pc. it only took a 10mbit video to destroy my dx9 card, and 11000+ hours of great use.There is never enough definition for what is needed, what never gets used, and what is hyped 😛
To me. it is always go for the latest, not necessarily the most hyped. Just for the facts of evolution, and to bury the thought...what am I going to do to kill my card this time...?
 


What the hell are you talking about?
 
Pixel Shaders are little Pixies that live in your Graphics Card.
When it's connected to your monitor, they will fly up the cable and sprinkle Pixie Dust on the small portions of the monitor to make it change color.
(Hence why they are called Pixels.)

Clearly the more Pixies (Or Pixel Shaders if you prefer), that live in your graphics card the faster they can make pictures on your screen.

This is HogWartz 101 guys, come on..................
 

That's because they are directx 9 games with directx 10 hacked in. When (If) we start seeing games built for directx 10 we should see some improvements. It's not likely there will be many directx 10 games though with directx 11 around the corner and the fact that directx 11 is compatible with directx 10 hardware.

Assasins creed is an example of a game that performs better in dx 10 mode though, and it also supported directx 10.1 which made it much faster on ati cards (Although support was removed in a later patch for some ridiculous reason)
 
Someone that knows what they are talking about (not me), please update this thread.
DX 10 added Geomerty shaders.
Now with DX 11 there are:

Vertex Shader
Pixel Shader
Hull Shader
Domain Shader
Geomerty Shader, and
Compute Shader
plus...
Tessellator
Rasterizer
Input Assembler
Output Merger
Multi-Thread rendering, etc

Anyway, I think this thread is worth keeping alive.
 
Hi I'm new here to these stuff

I'm still confused about the vertex shading.

First of all, is the triangle the geometry of the 3D object? As in an object is made up of many triangles.

If so, does vertex shading means that the geometry of an object can be dynamically changed in real time? Since the vertices of the triangle can be change, therefore allowing a dynamic change of object shape?

Would be glad if anyone can help me out here, heh. Thanks
 
Hornet85, you've got it. Now image all those triangles connected together and shaped into a 3-D skin of a dragon or a tree or whatever. The faster and more precisely you can manipulate them lends it's self to what he was talking about with the fog or dimples in a face.
 
HI, that was a great post.. i was wondering the mechanism of this for a long time and now i am pretty clear with this,, thanks man!!!!
 
Hi, what are the modern new graphics cards in the industry friends? I am undergoing a hardware class to know more about such factors....
