It's been forced down on intel chips because of https://bugs.kde.org/show_bug.cgi?id=252817#c194

how then to be used if the hybrid graphics Intel / Nvidia?

p.s.: for run 3D games, i use "optirun".

disable compositing: you can create a window rule for that, so that when you run a game it automatically disables compositing. That's way better than the fullscreen unredirection.

Otherwise you'd have to optirun kwin (because that's the relevant GL context), but in that case you'd better just deactivate the intel chip (as the nvidia chip is in permanent use)

But suspending the compositor is the better idea on performance concerns.
