Pixel shaders are a part of the graphics card. They are actual physical hardware. So you cannot add them to your PC unless you buy a graphics card.
e.g. Lego Star Wars II: The Original Trilogy
You don't count the pixel shaders. It's probably Pixel Shader 1.0 or nothing due to the horribly outdated graphics card you got.
you can download through internet or buy a new graphic card
Vertex and pixel (or fragment) shaders are shaders that run on a graphics card, executed once for every vertex or pixel in a specified 3D mesh. They operate in the context of interactively rendering a 3D scene, usually using either the Direct3D or OpenGL API.
Man PX 3.0 Supports the 6 series , the 8500gt supports 4.0 pixel shaders
The nvidia geforce FX series and 6000 series & up all have support for at least 2.0. this is true but not for all geforce series. you would have to have a 2000 to 3000 power on your nvidia grapghic card.
Pixel Shaders are on video cards. If you have an old video card that doesn't have pixel shaders, then you have to buy a new video card. If you want something that can play newer games, then something like the nvidia 8 series or the ati hd series would be good. If the games are kinda old then you can settle for the older series of cards.
Visit the manufacturers website and view the technical specification for the card.
yeh it does, and you can change the Shaders settings from the game
Shaders
If you only get 1 fps when using shaders, the reason is likely that your computer isn't powerful enough to run shaders. If this is the case, consider lowering graphics settings. If not, try reinstalling shaders and Minecraft.
Yes it does, you can check all the specs at the link below. http://ati.amd.com/products/MobilityRadeonx1400/specs.html
