installing a generic intel drivr instead of customized computer manufacturer driver may cause technical issues .contact your computer manufacturer for the latest driver for your computer tryed your way , and i get this again A customized computer manufacturer driver is installed on your computer.The intel driver update utility is not able to update the driver .However, they may release small updates that attend to these kinds of glitches periodically or when a serious issue arises.So long as Software Update reports no new updates, you will be running the latest drivers available for your Mac. Additionally, what you describe is not normal and I would suggest you see a Genius at an Apple Store (not a licensed vendor).Most of your Windows drivers will never need to be touched right out of the box.Your video card is in its own sacred territory though.That is why it is always recommended to update to the latest driver versions for your operating system.
Anything less than red-carpet service is not typical of the company and you should speak to a representative; they will make things right and may investigate matters.
Video card drivers are updated more frequently than, for example, your network card’s drivers.
Updating your video card drivers can show a huge performance boost across your system, as well.
I'm running on Windows 10, do you think it comes from that ?
Or is it just the driver that definitely needs an update ?
