- I was missing some kind of ping analyzer to find optimal
- pushlatency setting (movement prediction) on quakeworld
- servers, so i wrote panalyzer, a small cli tool that can
- read up to 60 floats from commandline, seperated by spaces.
- The prog then finds the median and stores highest and lowest
- value as range. Output: median [low-high]. The accompanying
- scripts use qstat to generate pings, stores the values in
- env variables and feeds them to panalyzer.
-
- All you have to do is move PAnalyzer dir where you want it
- and doubleclick the PAnalyzer icon. You will be prompted
- with a string requester asking for the server, followed by
- an interval requester (1-3 are suitable values).
-
- The script will update the calculation for every 5 pings.
- the median and range becomes reliable after the first 4
- updates (panalyzer uses the past 20 pings for calculations).
-
- Pushlatency determines how far ahead in time your quakeworld
- client should predict player and object movement. It is
- extremely important to set an ideal pushlatency in order to
- minimize the effect of delay between you and the server.
-
- Pushlatency should be set to the negative value of a position
- somewhere between lower limit and median. If median is close
- to lower limit, a suitable value would be the negative value
- of the lower limit. If median is close to the center of the
- range, it would make sense to choose a value equal to the
- negative value of the median. Generally, pushlatency should
- not exceed -250, because the quakeworld prediction will have
- more errors, the further ahead it has to guess. A wrong guess
- manifests as a sudden position-jump. You may miss a shot by
- a large margin or run into an obstancle you thought you had
- passed, because the server sends an update which differs
- significantly from the prediction.
-
- Example1: 44 [36-1044] would translate to a pushlatency of -36.
- However such a large range indicates an unstable connection
- and you can expect occasional lockups with delay up to 1 second.
-
- Example2: 92 [65-130]. Ideal connection with narrow range.
- Pushlatency shoud be set to -90.
-
- Example3: 166 [110-223]. This is a good connection with a
- relatively narrow range. Pushlatency should be set to -160.
-
- Example4: 285 [250-401]. Relatively good reliability.
- A reasonable pushlatency value would be 200-250, depending
- on your willingness to accept above mentioned position-jumps.
-
- Tips when searching for good servers:
-
- Narrow range, low median: very enjoyable, stable connection
-
- Narrow range, high median: enjoyable, stable connection.
-
- Wide range, median close to lower limit: mostly enjoyable, occasional lag.
-
- Wide range, median close to middle: not enjoyable, unstable connection.
-
-
- Have fun with this little tool!

- history:
-
- v0.2:
- Rewrote panalyzer to take a parameter -f for float output
- and -i for integer output and up to 60 vaues. Now finds
- median instead of mean. Data from pinging was generally not
- normal-distributed, so mean could be far off, resulting in
- too high estimates for pushlatency.
-
- Changed calculation update interval from 1 to 5.
-
- Added the info for using panalyzer as pushlatency guide.
-
- v0.1 First release
-
- future: make panalyser part of GameTracker, so that pushlatency
- can be set automatically, ahead of connecting.
