Games + Steam = Not smooth

[Reding]

Hi all,

I reinstalled Steam on my new Kubuntu 15.10 setup and Steam works fine. However when i play games (Half-Life, Bastion), they unfortunately aren't running as smoothly as they used to be. I have annoying little but noticeable flicks and the game gives the impression to "hang" a little bit which was never the case before.

Have someone experienced these problemes before ?

I have Intel HD integrated graphics (which i updated to the latest version hoping it would solve the problem).

Cheers

It's me again answering to myself

I found the solution for this actually. Basically you need to tweak your compositor options. By switching it totally off (disable compositor on startup for example) you get the best gaming performance.

Does someone know a way by any chance to disable the compositor with a keyboard shortcut ?

alt-shift-f12

also, there should be a setting there to suspend compositor for full-screen windows.

Brilliant. Thanks a lot.

There's a setting in compositor indeed but it specifies that it doesn't work on every hardware (apparently mine isn't compatible indeed).

Anyway to force it ?

Did you try it? The warning itself is just saying that it might not work for everyone.

I tried. Doesn't work

Cool stuff. I don't really understand how to make it happen with steam though.

This should work:

Copy and paste the following code into a text file (SteamStart.sh) and save the file somewhere (I have a "Scripts" folder just for little things like this).

Open a terminal and change to the "Scripts" folder. Make the script file executable (chmod +x SteamStart.sh).

To make the Kickoff Start menu entry for Steam start with this script (rather than run Steam directly), right mouse click on the "K" start menu icon, choose Edit Applications. Find the entry for Steam and change the entry to point to your script file.

#!/bin/sh
qdbus org.kde.KWin /Compositor suspend
/usr/bin/steam %U
wait
qdbus org.kde.KWin /Compositor resume

Sorry for the long silence guys, i had to deal with some life issues.

@Rod J: Your solution worked. Thanks a lot.
