I have sis 530 it has a setup for opengl but yo site does not say anything about being supported and the updates do not detect my hardware it would be great if you made a new updated driver that would be most helpful
its the cards chipset manufactures (ie SIS) task to write and provide the drivers.
IIRC sis havent gotten around to providing opengl support for the sis530
u might wanna try this anyways http://www.sis.com.tw/support/download/530.htm
either that or buy another graphics card (ie not one attached to the motherboard) even one from 3 years ago will provide far better speed than what u currently have
