How to Know If the Game Is Run on GPU

[Furkanzmc]

Hi.
Is there a way to know If the game is run on GPU or integrated graphics card so that we can activate different effects for each graphics card being used?

[G.]

What kind of effects?
I don't think it's possible, and what would it mean? Some newer integrated graphics cards are easily better than older GPU isn't it?

If you're using shader, you can test if shaders are available.

OK, thank you for the answer.

You can check the result of glGetString(GL_VENDOR) and glGetString(GL_RENDERER) to identify the graphics card/driver.

Strings GL_VENDOR and GL_RENDERER together uniquely specify a platform. They do not change from release to release and should be used by platform-recognition algorithms.
