I haven’t had CTDs with this method. If anything it should lessen the chance of a hardware induced CTD as your system is not being maximally loaded, so it should be way back from the edge of hardware stability.
Yes it would be better if an equivalent feature would be added to MSFS so you could toggle it internally. However, I learnt long ago not to hold my breath waiting for fixes, let alone obvious improvements, to MSFS, so if I can find another way to achieve the desired outcome now I just do it.
