[Bug 2149792] [NEW] games stuttering/freezing in kernel 7.0.0-14

Public bug reported: I play Call of Duty Black Ops 2 Zombies on steam using default proton settings. No special proton settings. I play Far Cry 3 on steam with the glorious eggroll custom proton. Using kernel 7.0.0-14 Zombies gives me a brief freeze frame almost like somebody hit a pause button that is making it hard to play. Using kernel 7.0.0-14 Far Cry 3 occasionally gives me audio that sounds like a cd player skipping or something. If I run zombies in window mode, and btop running next to it, I can observe that the freeze corresponds to a drop in CPU usage. Some times it goes from maybe 20 percent and then freezes and drops to 2 percent. If I enable "X3D turbo mode" in my computer bios the freeze seems to go away, but I only have 8 CPUS now. If I go back to kernel 7.0.0-13, the freeze problem also goes away. This makes me think its a bug in the kernel but I don't know it could be a bug in something else. Sorry I have never debugged a linux kernel before.
