Memory integrity enabled or disabled for Windows 11 games

In this video, we'll test the performance impact of core isolation, or memory integrity, in Windows 11 on gaming. Core Isolation is a newly introduced security feature that can be disabled manually (it's enabled by default) and can improve your frame rates by up to 15% when disabled.

In this video we will test Fortnite, Cyberpunk 2077, F1 2020 and Counter-Strike Global Offensive. I chose a few CPU-intensive games and then also applied a CPU bottleneck in Cyberpunk, since core isolation has a much greater impact when the CPU is bound.

I chose these 4 games because they have built-in benchmarks, and with Fortnite you can use replays for consistency. Each benchmark was run three times and the video shows the best run of the three for each game and setting.
