Symptoms

When running the game through gamemoderun using core pinning, the game will crash shorty after launching. Usually pretty early on, but sometimes a bit longer.
In ~/.config/gamemode.ini if I set pin_cores=0-15 under the cpu section, this happens. If I use core parking instead, there's no problem. Other games don't have this issue so it seems specific to GoW: Ragnarok. I've tested with other Sony games such as Days Gone, Ghost of Tsushima, Spider-Man: Miles Morales without issue. Also all non-Sony games I've tested are unaffected.

As it doesn't happen other games, this is likely a bug that gamemode is simply able to trigger through pinning. Maybe it's a DRM check of some kind in GoW?

Reproduction

1. Edit ~/.config/gamemode.ini
2. Set pin_cores=0-15 under the CPU section (unsure if this affects single CCD systems, etc).
3. Run God of War: Ragnarok with the following launch options: SteamDeck=1 gamemoderun %command%

For now I can keep using core parking, but it would be nice to have the rest of my cores available for other tasks as I play.
