Hii Guys ,

I have Sony Vaio VPCCA15FA with the following specs.
Intel Core i5 2.3 Ghz
6 GB DDR3 Ram
AMD Radeon HD Mobility 6630m ( btw it is switchable graphics , dynamic mode ) , and there is no option in the bios to turn off the dynamic mode .
I have this error when i run the game (GL_ARB_draw_elements_base_vertex not available) , and btw i installed Rage Performance Driver and 11.10 Driver Preview 2 & 3 , and nothing happens also,
the error keeps coming up.
Any ideas what should i do to make it run ??
Pleeeeeeeeeeeeeeeese Help.
Thanks in advance.

Uninstall your Radeon video card driver and install the newest ATI video driver, thats why you are getting the error.

Get the new Driver here: http://www.gamesas.com/index.php?/topic/1242719-new-preview-3-driver-fixed-my-ati-issues/

Hope this has fixed your issue

still the same problem :(

I think the problem is in the switchable grphics , do anyone know how to disable Intel graphics and make AMD the primary gpu ??
