Disable compositor for WINE games?

[claydoh]

Why do you want to?

Because some people may have a potato for a system, and/or want all the GPU cycles to be used for their game, not the desktop UI. Or they need it for something running in a VM using the GPU directly. Funky drivers. Or any number of other reasons not necessarily related to games.
Some things that run in a window (not full screen) can get bogged compared to doing so full-screen, where the compositor is turned off automatically if the game requests it.

Certainly this is less necessary these days on middling to high end graphics, but not all have such systems.

Why do you want to? I have literally zero problems here with games and compositing operating simultaneously

I have not noticed any difference so far and I think claydoh is right: the compositor is disabled automatically for my game (probably also due to the setting in System Settings -> Display and Monitor -> Compositor -> Allow applications to block compositing ).

Thank you for your thoughts.
I will keep an eye on it and report back if I observe anything worth reporting (e.g. in crowded fighting scenes).

If you run the game full screen, the compositor is automatically disabled. or it is supposed to be.

I used to manually disable it, back before Kwin did so on its own. But back then, in the dark ages of Linux gaming (2010-ish?) I had dinky potato level GPUs, and it did make some difference, but not enough to hurt things too much if I forgot.
I don't even think about it these days, even when I still had under-powered cards.
If you can't tell, then it isn't hurting performance Or it is being disabled for you.
But you may want to test on a busy or action packed scene to really know.

Up to this point I have only very occasionally played Linux games like 0 A.D., Endless Sky or Pingus on my computer.
But being a huge fan of The Witcher 3 on my PlayStation I recently decided to buy a second hand Windows version of The Witcher 2 Enhanced Edition.

This is my first Windows game I run in Linux. I have installed it using Lutris and it runs like a charm in 1680 x 1050 with maximum graphics settings (on my AMD iGPU !!!).
I even use my PlayStation controller without problems to play it.

And here comes the question:
-> Should I disable the compositor before running The Witcher 2 in Lutris/WINE? (E.g. manually with qdbus org.kde.KWin /Compositor suspend)

Honestly I am not sure if I can tell any difference between running The Witcher 2 without and with the compositor enabled - but I have only just begun playing it…

What are your experiences with Windows games running in WINE in this regard?
