Title: Apparently, my computer doesn't support the Shader feature, so what can I do?
Post by: awsumpwner27 on December 30, 2012, 08:56:14 am

I checked out the examples, and I was disappointed to find out that the Shader example didn't work. I updated my graphics driver, hoping that it would make a difference, but it didn't. I got this computer about 4 years ago, and apparently I'm using a "Intel(R) G33/G31 Express Chipset Family" graphics card. Also, the driver update I got was about 3 years old. :|

So, what are my options?

If sf::Shader::isAvailable() returns false, then there's probably nothing you can do.

It depends on the OpenGL version supported by your GPU, if it uses a version lower than OGL 2 then you can't do much about it since it was from that version that GLSL has created and therefore supported. sf::Shader::isAvailable() probably returns either true or false according to you OGL version.

Not exactly, it checks the corresponding extensions.

Well, how bad of an idea would it be if I implemented shader-like effects without the Shader? I imagine it being slow since it wouldn't be able to use the GPU.

You mean, downloading the intermediate rendering to a pixel array in RAM, applying the "shader" manually pixel per pixel, and then uploading the result back to a texture and displaying it with a sprite? That would be incredibly slow :)

I figured.

Well, thank you for the info.

Maybe you can update or get a new machine?
It'll be worth it.

Getting a new computer is a possibility that isn't favorable enough to depend on. I don't nearly have the money to afford it.

What effect do you have in mind?

Maybe shaders are not the only option to achieve it.

What hardware are you on, out of curiosity? Shaders not being supported suggests it's extremely old hardware or extremely outdated drivers.
