How to modify igdkmd64.sys to make it compatible with Windows 8.1?

[Claudiu31]

Hi everyone. I have an asus with :

- processor intel N4500

- architecture Jasper Lake

- Intel UHD Graphic

The problem is that the PC is slow on windows 10/11 and I don't find anywhere a graphic driver  for Windows 8.1. I read here (https://winraid.level1techs.com/t/intel-uhd-graphics-630-video-driver-for-win7-x64/33098/29)  and I saw that someone modified the drivers for Windows 7/8.1, but the last one is for 10th generation Intel, and my Intel is 11th generation. Does anyone know how to modify the igdkmd64.sys or where to find a driver for Intel UHD Graphic Jasper Lake for Windows 8.1? Thank you!

It may be slow on W10/11, but those are the operating systems supported.  W8.1 is from 2013, the processor is from 2021 (8 years later).  Tis also means that the processor graphics were not intended to run on W8.1 or earlier, and are not supported.

You will not get the hack/mod you want from here.  If performance is your issue, get a faster processor and run W11.

This is 2025
