OpenGL question

My laptop has a SIS Mirage 3 inbuilt chip. Far from the best I know! According to the specs I have read it supposedly supports OpenGL version 1.5, which is the minimum spec in the requirements for Max 6. However if I try to open a patch with OGL objects in it I get a series of error messages.

Looking at the OGL Ststus in MAX it looks like it is not recognising the chipset as having OGL features at all…

{
“Renderer” : “invalid”,
“Vendor Name” : “invalid”,
“Version” : “invalid”,
“GLSL Version” : “invalid”,
“OpenGL Limits” : {
“Framebuffers” : {

}

}

“MAX_VERTEX_TEXTURE_IMAGE_UNITS_ARB” : [ 0 ],
“MAX_VERTEX_UNIFORM_COMPONENTS_ARB” : [ 0 ]
}

}

}

Anyone know if/how I can fix this?

Cheers

you’d have better luck with c74 support directly or that chip merchant support probably

I would ensure you have current video drivers and current bios. Try and get these from your laptop manufacturer. If not available there, you can try the SIS site at http://w3.sis.com/download/agreement.php?url=/download/

Sometimes, the drivers you get from Windows Update will not have full OpenGL capabilities. The WU drivers are generic and do not necessarily support all features.

Once you have current drivers, try the OpenGL extension viewer as a test. It is available at http://www.realtech-vr.com/glview/
