The only part of physx in that game that I remember is that it used to cause massive performance and stability issues.

Twice, because usually it’s two sticks.

In any case, RAM failure is rare enough that quadrupling its chances is not gonna make any meaningful difference. Even if it does, RAM is the easiest thing to replace in a PC. Don’t even need to go offline while waiting for a new stick. Someone who’s got the cash to build that thing in the first place won’t be too upset by the cost of another 32gb stick either, I don’t think.

This concept isn’t new either. Factories have been using very similar methods to use the heat of the exhaust gasses to power the sensors and whatnot on top of their smoke stacks for some time now, for example.
