Performance guide
</h1>
<p>
Getting the best performance possible from your hardware while running AssaultCube, without sacrificing
too much quality is important to most players. A lot of newer hardware will run AssaultCube very well,
with no changes neccesary, but some older hardware may need some optimisation to get a good result.
This guide details some ways on how to do this.<br />
<b>Note:</b> Although many settings can be changed in-game, for ease of explanation and understanding, this guide only
details the way to change the settings through configuration files <b>outside</b> of the game.

Graphics drivers
</h2>
<p>
The best way to get the best performance out of any 3D application is using the latest and correct drivers, with the
correct settings. AssaultCube is no exception to this rule. If you have any problems running AssaultCube, always check
your drivers first!
</p>
<p>
To download and install the latest and correct drivers, follow these steps...
<ol>
<li>
Find out the correct name/make/model of your video card.
</li>
<li>
Go to the driver/support section of your video card manufacturers website (e.g.
<a href="http://www.nvidia.com/page/drivers.html">nVidia</a>, <a href="http://ati.amd.com/support/driver.html">ATi</a>,
<a href="http://downloadcenter.intel.com/">Intel</a>,
<a href="http://www.matrox.com/graphics/en/support/drivers/">Matrox</a>, etc)
and download the latest and correct drivers for your model and operating system.
</li>
<li>
Install and configure the drivers as per the instructions given to you by the manufacturer (make sure previous
versions of the drivers are uninstalled).
</li>
</ol>
</p>
<p>
Some operating systems and graphics cards have other special drivers and methods that you can explore for your drivers.
Microsoft Windows users may benefit from <a href="http://www.omegadrivers.net/omega_drivers.php">Omega Drivers</a>,
some nVidia Microsoft Windows users can try using <a href="http://www.nvidia.com/object/ntune_5.05.54.00.html">nTune</a>.
Linux users might like <a href="http://www.albertomilone.com/nvidia_scripts1.html">EnvyNG</a>.
</p>
<p>
<b>Warning:</b> If you're using a laptop, you may need to consult your laptop manufacturer for drivers, as laptop graphic
drivers are heavily customised.
</p>
<p>
<b>Note:</b> None of these links or drivers are endorsed, maintained or supported by the AssaultCube team.<br />
Use these links at your own risk. We highly advise it to be best searching the forums and support pages for
your operating system supplier or graphics card manufacturer if you are having problems with 3D graphics rendering.

<p>
<b>Note:</b> Where applicable, if there is a way to change the setting through the AssaultCube client, it has been
mentioned (note: in most situations, the drivers need to be enabled in such a way for AssaultCube to be able to change
these settings) but because graphics settings differ from card to card, there may be options mentioned which are
unavailable on your card and many options can't be changed through AssaultCube.
For these situations, please consult your graphics card manufacturer to find out how to do this. There are also many
options for video card performance and eye-candy which are not covered due to the vast amount of them, in that case
we suggest you check with your video card manufacturer for what else you can do to improve performance as this
guide only covers some of the more common ones.
</p>
<h3>
Resolution
</h3>
<p>
Your resolution in-game determines the amount of detail on the screen. The higher the resolution you use, the more the
graphics card has to work. If you are having problems with low frame rates, lag or stuttering, then lowering the
resolution will yield the biggest result.<br />
Note: LCD panels typically work best at their native resolution rather than a bigger/smaller one.
</p>
<p>
To change the resolution of your screen, add these parameters to your AssaultCube launcher:<br />
<span class="code">-h<b>X</b></span> - Replace <b>X</b> with your new resolution height.<br />
<span class="code">-w<b>Y</b></span> - Replace <b>Y</b> with your new resolution width.
</p>
<p>
(Instructions on editing the AssaultCube launcher can be found <a href="commandline.xml#launcher">here</a>).
</p>
<h3>
Refresh rate
</h3>
<p>
Making your refresh rate happen at a higher level can generally help increase FPS. Ways to do this differ depending on
your system and setup (consult online documentation for your operating system to find out how).
</p>
<h3>
Colour quality
</h3>
<p>
In most systems, you are able to change the colour quality which may boost your performance. Normally you have a
range of 16/24/32 bit. The ways to change this differ depending on OS, consult your OS manual.
</p>
<h3>
V-sync (AKA: Vertical refresh)
</h3>
<p>
Vsync is a method of synchronising the frame rate of games to the refresh rate of the monitor. Turning on Vsync prevents a
graphic phenomenon called "tearing" from occurring. Screen tearing can occur when the frame rate being output from the
video card is higher than the refresh rate of the monitor and can make the screen look torn into sections and moved
with the high speed motion of the game. Turning this off can help increase performance for many players, but if you
experience tearing, it may be best to turn it back on.
</p>
<p>
To turn Vsync off, add this line to <a href="../confg/autoexec.cfg">autoexec.cfg</a>.<br />
<span class="code">vsync 0</span><br />
(<span class="code">vsync 1</span> enables vsync).
</p>
<h4>
Triple buffering
</h4>
<p>
If you use V-sync, enabling this can help improve overall performance in OpenGL games such as AssaultCube. However, if you
don't have enough video RAM, this may cause lag and problems.
</p>
<h3>
Anti-aliasing
</h3>
<p>
Anti-aliasing is a process that attempts to smooth out the jaggedness of diagonal lines in a 3D game environment.
To turn anti-aliasing off, add this line to <a href="../confg/autoexec.cfg">autoexec.cfg</a>.<br />
<span class="code">fsaa 0</span><br />
(<span class="code">fsaa 1</span> enables anti-aliasing).
</p>
<h4>
Temporal antialiasing
</h4>
<p>
Some graphics cards support "temporal antialiasing". It's basically a driver trick that gives the effect of a
antialiasing, but with less work needed by the graphics card. Try it out, as it is a faster method of
antialiasing, but if you don't like it, or it's still too slow, don't use it.
</p>
<h4>
Adaptive Anti-Aliasing
</h4>
<p>
This is an antialiasing technique which improves the appearance of transparent textures. The performance impact
should not be significant over normal antialiasing, but if you don't like it, or it's still too slow, don't use it.
</p>
<h3>
Catalyst A.I (ATi only)
</h3>
<p>
If this is enabled, it allows ATi graphics cards to make graphics "shortcuts", normally with no noticable reduction
in image quality. It is best to enable this to give yourself better performance.
</p>
<h3>
Mipmap Detail Level
</h3>
<p>
This helps determine how good textures generally look, when combined with AssaultCube's own texture settings.
Changing this can help gain/loose some performance by making the textures appear duller or sharper.
</p>
<h3>
Anisotropic filtering
</h3>
<p>
Anisotropic Filtering helps make textures (the 2D images covering the surface of all 3D objects) at a distance
appear clearer. Setting this lower may help improve performance.
</p>

<p>
After upgrading to SP3, mice with overclocked USB ports get their polling rates stuck at 125hz. This can be fixed:

Download the <a href="http://files.filefront.com/mouseraterar/;10969699;/fileinfo.html">mouserate checker</a>.
Then download the new <a href="http://files.filefront.com/hidusbfzip/;10969768;/fileinfo.html">USB port overclocker</a>.
Unrar them both. Go to the driver folder and then install executing "setup".
</p>
<p>
Then, open the USB port overclocker. Tick 'Filter On Device'. Choose the polling rate you want. Keep "Mouses only" ticked
to save yourself from confusion. Make sure you've clicked/highlighted your mouse. <b>Install service</b>. Then restart.
</p>
<p>
Then check your hertz with the mouserate checker. If it doesn't read out that its been altered you'll probably have
to restart. Also if you change what port you plug your mouse into you'll have to repeat the process.

If you wish to upgrade your systems hardware, please seek advice elsewhere. There are plenty of resources available online!
</p>
<p>
When running AssaultCube, it would be wise to turn off any un-needed applications, especially those that suck down CPU
performance and graphics rendering. For example: Turn off compiz, music players, windows defender, etc. Also try turning
down the graphics settings used by your operating system for everyday tasks.
