Q2PRO is an enhanced Quake 2 client and server for Windows and Linux. Supported features include:
Q2PRO doesn’t have releases. It is always recommended to use the latest nightly build linked below. These builds are regenerated automatically once a commit is made into the git repository.
Linux binaries are not provided. Users are advised to build from source. See INSTALL file inside the source tarball for instructions.
For historical and testing purposes, some older builds are available here.
Latest development source code can be obtained from Q2PRO github.com page. You can also report issues you have with the latest code there. This site also hosts a local mirror of the git repository.
For building Q2PRO please consult the INSTALL file.
gl_modulate setting. Q2PRO defaults this to 1, while other
clients may have different default values.
Q2PRO is very well suited for playing with vertical sync on. In fact, it is
recommended to enable vertical sync for smooth, tearing-less rendering.
Assuming you have
cl_async enabled, it is important to set
correctly. It should be set equal or slightly lower than the vertical refresh
frequency of your monitor (typically 60 Hz for LCD monitors). You can check
your current movement FPS by executing
echo $cl_mps command. When configured
properly, it should be equal to your
This is a harmless effect caused by protocol 36 attempting to reduce outbound
traffic and sending packets with frequency limited by
cl_maxfps used by other protocols. Since default value of
cl_maxpackets is 30 (lower than typical
cl_maxfps value), server
miscalculates your ping to be slightly higher. This does not affect your
gameplay experience in any way: events like pressing
+attack are instantly
pushed to the server. Ideally, server should be configured to use improved ping
calculation method that uses minimal network latency instead of average latency
to avoid possible confusion. (This is now the default in latest Q2PRO server).
Those who used OpenAL sound system with R1Q2 client may find that Q2PRO sound is different in OpenAL mode. This is expected, because R1Q2 and Q2PRO use different OpenAL sound attenuation models. Q2PRO tries to mimic original Quake 2 software sound as close as possible, whereas R1Q2 uses custom model that makes sounds from plats and doors hearable at greater distances than normal. Q2PRO will not support this sound model because it contradicts its goal to be gameplay-wise identical to original Quake 2.
