Editing FTEQW Miscellaneous Features

== Introduction ==
This is a more or less random list of additional features of the [[FTE | FTEQW]] engine. If enough details are added, please turn the sections into their own pages.

== Rendering ==
Various featured related to rendering of the game-world or menu.

=== Scaling of menu ===
For especially for high resolution mobile devices or 4K displays it is useful to scale up the menu and HUD.

FTEQW has two options for this:
# /vid_conautoscale with typical values or 1, 1.5 or 2 (3, 4 etc.). This scales everything by the factor/value used.
# /vid_conwidth 640 and /vid_conheight 0 this autoscales a typical menu/HUD designed for a 640x480 screen to the full screen size while retaining the aspect ratio.

=== Mega Screenshots ===
This feature uses render-to-texture rather than rendering stuff to whatever puny window you have. This allows the high-resolution screenshots, for example 16384*16384. Each of these commands take a filename argument followed by width then height. The width and height are still limited by your GPU, but have absolutely no dependency on your monitor or window size etc.

   screenshot_mega: Takes a ‘simple’ large screenshot.
   screenshot_stereo: Takes two screenshots side-by-side with a small(r_stereo_separation) offset (also assumed by screenshot_mega with the .pns extension).
   screenshot_vr: Takes many many many screenshots giving a horizontal 360 perspective that can be viewed with a few different display software.

The resulting file-name will be displayed in the console (as a more easily findable system path).

=== r_renderscale ===

This renders the game view at a different resolution than your screen. 
* A value of 2 is good for supersampling, giving a smoother appearance even mid-surface (unlike msaa), without needing to resort to blurring (read: fxaa) 
* A value of 0.5 can give a small speedup with complex scenes involving many rtlights or reflections
* Values above 1 should not normally be used in conjunction with /r_fxaa. The result is not desirable, while smaller values are positively weird, but awesome with it.

=== Stereo rendering and early VR stuff ===

 r_stereo_method 5

for cross eyed 3D stereo rendering.

Some work was also done on WebVR support, but it is unclear if and what is actually working.

== Download Menu ==

The in-engine download menu provides easy access to install/uninstall additional packages, or simply update them more easily. 
* Find Quake re-texturing packages and rtlight definitions 
* Also the in-game editor (which needs cheats or singleplayer to use)
* A number of additional plugins.

Can be opened from the console with 
 /menu_download

== Paths ==
Paths can be annoying. Assuming that you don’t want to use “My Documents” folder to keep your game data, confirm that FTE is using the current folder by typing /path in the console.
* If it prints “My documents”, start FTE with the parameter -nohome, and create a shortcut to it
* If you want to see which package a file is inside, you can use “/flocate maps/foo.bsp” for instance. Alternatively you can use “/dir maps/foo.bsp” and it’ll list each occurrence of that file including the package/gamedir that contains it

== Idling ==

 snd_inactive 0; 

* will no longer play sounds while the window is not focused (on some systems anyway). needs a snd_restart though.

Regarding inactive cpu when game is minimized: set cl_idlefps to something low like 10 and the engine will sleep between ticks. You can also set cl_yieldcpu to 1 to reduce cpu usage with vsync off (or with low cl_maxfps).
