There is a new wave of games coming which use advanced physics, think destructible voxel worlds, like minecraft but having blocks of 1cm instead of 1m. VR benefits immensely from CPU/GPU overkill and can use any cycle it can get. The status quo you see now is caused by CPU stagnation not the other way around. Once tech finds a way to afford more cycles games and applications will find ways to use them (and not just by wrapping them with Electron :).
