Sometimes the Update Driver option and the Hardware manufacturers website may indicate you have the latest driver, when there is a newer version available on the Intel website (check the driver release dates on Intel site).
be aware, that notebook makers do provide modded (throttled) graphics card drivers for ensuring the termal design is not exceeded and the cooling system not overrun sothat in consequence the GPU and thus the system is not overheated… using the general driver of the maker of the GPU may therefore lead to unwanted effects as described above typically accompanied by an increased power consumption and a loss of guarantee in case of a defect.
this heavily depends on the maker and the type of the model series dedicated to consumers or business users with the latter reguarly provided with a long term support for support/service as well as driver availability, one reasion for the higher pricing of business devices (as e.g. Lenovo ThinkPads or HP ProBooks or Dell Precision etc.).
Note that after step 10, inside the Graphics folder, you should click on the file that starts with “ig” and then click on Open, then Okay on the next window, and then “Next.”
You may need to reboot your computer at this point.
Now you can relaunch SketchUp!
