Hello,

For whatever reason, I got the bug to go back to my XP Pro 64bit machine for some old games that were missing features or a pain to get working in the latest versions of our chosen OS and hardware.

There are probably not that many of you who are crazy enough to want to unlock the full HDMI 2.0 bandwidth in Windows XP. However, if you are, I can provide the steps to do so. There are D3D9/XP era games work with widescreen, and the GTX 980 Ti 6G or Titan X can push some of them to 1440p 120hz. This makes some 1440p OLEDs great for this task. Especially, if you're too lazy to move or repair your aging CRT 😀. Unfortunately, all of the drivers provided by NVIDIA that you can get working with said GPUs, are limited to a bandwidth / pixel clock of 135MHz.

I should thank whoever 'Sera' and 'Yas' are over at the following post for most of the work:

The work that Yas did was patched into the driver files available here: https://archive.org/details/NVIDIAHDMIPATCHXP. Unfortunately, it was only updated to 340MHz bandwidth. This is working starting with the 355.98 drivers. I will attempt to rework for the latest XP drivers at a later date (I have noticed FPS increase with 368.81).

I'm not sure if there is any terms of use or legal issue outlining the steps in this forum, but please tell me if it is OK to do so. I figured it would be better to describe the process, rather than provide the modified drivers. But, maybe for 11 year old drivers it is OK to do so?

Thank you.
