I have a questions (please help)

On my OpenGL settings for my graphics card they give me the option to enable:

-Use fast linear-mipmap0linear filtering

-Disable support for enhanced CPU instruction sets

-Enable conformant OpenGL texture clamp behavior

What are these options? Are they worth enabling and will it enhance my look of the games I play?

Any information would be appreciated,


  • don’t know what the driver do when this box is checked but I’m pretty sure that it decrease the quality of trilinear filtering

  • can’t you read? it disable enhanced CPU (SIMD instructions like SSE, 3D now, MMX) instruction in the openGL driver, sure it does a slowdown

  • nvidia card default setting clamps to edge each texture that use the GL_CLAMP paremeter. Check this box and your driver will really clamp texture

BTW it’s a programming forum here
