I ve picked this machine for keepin it with, had it setup with win7 and latest bios / drivers. I have vid drivers directly from intel and what ive noticed - bby spec this 3150 gpu should support opengl spec 1.5 but in reality it is only 1.4.
Asked intel about that and .. are u doing some tweaks on this chip redusing its caps ? I gues no. here is the log:
Victor: Hello. Thank you for using the Intel Customer Support chat service. We are glad to be of service. How can I help you today?
you: Just 2 questions regarding openGL support for 3150.
you: 1st why intel site is saying it can support spec 1.5 over windows but in reality it is 1.4
Victor: This will depend on the driver that you have.
you: i have win7 and recent drivers
you: they are 1.4
Victor: Is this an OEM computer like DELL*?
you: like lenovo
you: but drvs are from intel site of cause...
Victor: The chipset may have been customized by your system manufacturer. You should contact Lenovo* to confirm the compatibility.
you: ok 2nd why it is spec 2.0 on linux but spec 1.? on win.
you: really it is a bit silly - cutting hw caps on most popular os.
