📎 AI Summary:
The thread discusses attempts to change the interrupt affinity for the DirectX.sys driver to reduce CPU core interrupts, with the original poster seeking solutions and sharing efforts with registry edits and WDK. A suggested tool for managing interrupt affinities was mentioned, but it was deemed ineffective because DirectX is a system driver, not hardware, making such adjustments challenging. Overall, the user expresses frustration and uncertainty, noting that official Microsoft documentation hints at potential methods but lacks clear instructions.

Hi , I wanted to ask, if it is possible to change the Interrupt affinity policy of a driver, maybe in a specific regedit or is there an easy way to do it , I want try to set the directx.sys driver to another core to get less interrupts on core 0. I tried many regedits they all don't work, now iam trying it with the wdk. If someone already got a solution how to set specific affinities to specific cores, please tell me ❤️

Lov ya,

The thing is that directx is a system built in driver and not a hardware driber ,so the interrupt affinity tool doesnt work here , but thanks for the reply
Damn... not sure then. We could ask the AI... its possible someone else might know.
I terrorized Gemini and GPT already nothing there but Microsoft documentation says it's somehow possible , but not how 🤣🤣
