It sounds like there’s a specific set of CPU instructions (or a specific sequence of them) which are especially affected, which that game engine uses much more than most other software
Because other CPUs don’t have this problem. If the game engine is problematic then many other CPUs would show something. The game engine is just the trigger, much like a seizure can be triggered on some people by flashing lights but not others.
Certainly could be a CPU issue, but if all the affected games use the same engine, I don’t know why you would conclude that.
