containing the binaries is used.

||||
## General
|
||||
|
||||
* **busywait**: By default this is set to `1`. causing Quake II to spin
|
||||
in a very tight loop until it's time to process the next frame. This is
|
||||
a very accurate way to determine the internal timing but comes with a
|
||||
relatively high CPU usage. If set to `0` Quake II lays itself to sleep
|
||||
and tells the operating system to send a wakeup signal when it's time
|
||||
for the next frame. The later is more CPU friendly but rather inaccurate,
|
||||
especially on Windows. Use with care.

inaccurate, especially on Windows. Use with care.
|
||||
|
||||
* **cl_async**: If set to `1` (the default) the client is asynchronous.
|
||||
The client framerate is fixed, the renderer framerate is variable.
|
||||
This makes it possible to renderer as many frames as desired without
|
||||
any physics and movement problems. The client framerate is controlled
|
||||
by *cl_maxfps*, set to `60` by defaut. The renderer framerate is
|
||||
controlled by *vid_maxfps*. There are two constraints: *vid_maxfps* must
|
||||
be the same or greater than *cl_maxfps*. In case that the vsync is
|
||||
active, *vid_maxfps* must not be lower than the display refresh rate.
|
||||
If *cl_async* is set to `0` *vid_maxfps* is the same as *cl_maxfps*, use
|
||||
*cl_maxfps* to set the framerate.
|
||||
controlled by *vid_maxfps*. There are two constraints:
|
||||
|
||||
* **cl_showfps**: Shows the framecounter. The shown value is rather
|
||||
inaccurate and gets less precise with higher framerates, as it only
|
||||
measures full milliseconds.
|
||||
* *vid_maxfps* must be the same or greater than *cl_maxfps*.
|
||||
* In case that the vsync is active, *vid_maxfps* must not be lower
|
||||
than the display refresh rate.
|
||||
|
||||
* **in_grab**: Defines how the mouse is grabbed by Quake IIs window. If
|
||||
set to `0` the mouse is never grabbed and if set to `1` it's always
|
||||
grabbed. If set to `2` (the default) the mouse is grabbed during
|
||||
gameplay and released otherwise (in menu, console or if game is paused).

* **vid_displayrefreshrate**: Sets the displays refresh rate. The

default `-1` let the game determine the refresh rate automatically.

There's little need to change that. If you do make sure that the refresh

rate is rounded up, e.g. with a display of 59.95hz you should set `60`.
