-== In-game Overlay ==
+==Graphics Check==
-When using Steam or Discord, the in-game overlay should be disabled for maximum performance. It can lead to anything from increased lag to a completely unresponsive user [[interface]].
+{{{glxinfo | grep "Max core profile version"}}}
+It needs to show a number 4.1 or greater
+If it doesn't you need to do the following
-=== Disabling the Steam Overlay ===
+Do a backup before preceding. These instructions written for Debian 9.
-* Right click on Zero-K in your Steam library.
-* Select 'Properties' from the dropdown menu.
-* Untick "Enable the Steam Overlay while in-game" in General.
+==Backport libdrm from sid==
-=== Disabling the Discord Overlay ===
+{{{apt-get build-dep libdrm
-* In Discord, go to Settings -> Games
-* Look for Zero-K and click the button on the right to "Toggle Overlay". It should turn red.
-== Laptop Graphics Driver Optimizations ==
-===Switchable Graphics===
-On systems with two graphics cards, Zero-K may require an additional step to use the high performance Nvidia or AMD graphics card. If your frame rate seems too low for your hardware, check the following:
-* Open the infolog.txt from your Zero-K folder and search for the line starting with '''GL vendor'''
-* If the '''GL vendor''' shows as '''Intel''', you should make a rule in your driver software to run '''spring.exe''' in High Performance mode.
-* After making the change, run Zero-K again.
-* You can check the '''infolog.txt''' again to confirm that your system is using the correct graphics card for Zero-K.

-<pre>glxinfo | grep "Max core profile version"</pre>
-It needs to show a number 4.1 or greater otherwise graphically demanding games such as Zero-K won't run correctly.
-If it doesn't you need to do the following (or, as an alternative, upgrade all mesa-related packages from stretch-backports. As for now - Sep 2018 - it will bring Mesa 18.1 and "Max core profile" 4.5).
-The graphics stack in Debian Buster is new enough to bring "Max core profile" to "4.5".
-Do a backup before preceding. These instructions written for Debian 9 but will likely work on other distributions with little modification.
