Maybe should have done some test within this video but still very good presentation! Idea of next videos: fortnite and csgo with and without cp0. Tho Idk bout fortnite settings, but in csgo take maybe some s1mple or other pro settings which isn't 16:9 resolution, hope you understand the idea. Gl!

[@Alchemytweaks]

What tests would you like to see from this video ?

[@yashekwa499]

@@Alchemytweaks I assume the question is about DPC not CP0 right? Because cp0 it's understandable - to see does it really gives performance as it has talked about + even refrag optimization (you can check it, kinda simple, but interesting) says to put uncheck cp0. About DPC should have tested maybe tweaked vs untweaked systems, maybe even 2, 3, 4 settings that can really change the latency. F.e. putting network adapter to 1 core can reduce dpc from other cores, same with USB. Kernel is one of the top latency killers, so tweaking gpu driver or something. Tweaking audio too, you probably get where I am going, there are many things you can do to decrease system delay. But yeah, that takes some time, not much, but time is time.

[@Alchemytweaks]

This video didn't made to give you instructions about how to reduce latency , it's made to explain what is DPC & ISR .

[@yashekwa499]

@@Alchemytweaks I understand, but you questioned me what tests I would like to see, and I answered =D it's allright.

[@Alchemytweaks]

@@yashekwa499 Yes, you answered me and I answered you with what thought the video was made. The video was made to help you to understand 2 mechanism not to help you to reduce the latency of your system .
