Re: [hlds_linux] new cpu usage record?

[Nelson Marques]

Since everyone is talking about cpu usage and optimization, simple question:

- Anyone using icc compiler from Intel ? Does it bring anything nice
when compared to GCC ?

Ahhh, cool!   After reading through that article, I guess I don't need to
get my FPS up above 50 on a per server basis then.


Thanks Alfred!

p.s., lots of big words in that thar pdf. =P

FPS on the server and client are uncoupled. FPS on the client controls how
often a screen will render per second (i.e render latency). FPS on the
server determines how many times a second each entity can "think" (i.e issue
a fire command, move, get killed, and so on). A low FPS on the server will
NOT effect the FPS on the client. Note that Quake runs at 20Hz (20FPS) on
the server by default.
Running at 100FPS means you minimise the latency between a client issuing a
command and the server acting upon it. Also note however that network
latency will usually dominate over server FPS latency.
You should also take into account the minimum reaction/perception time of
human beings when trying to determine the FPS right for you (search google
for "perception latency human" or read
http://www.physiol.ox.ac.uk/~pch/papers/brain_122_2119.pdf. Common figures
for the latency in visual perception are on the order of 150msec. 100FPS
means a frame every 10msec (10 times less than the perception threshold!)).

What exactly does FPS Correlate to and how does it affect
game play?   I'm
sure there's also a high/low value for these as well, any
word on what those
might be?
I've got 2 pubs that are full 24x7 and the regulars love the
connection/servers.  They've never griped about anything (short of CPU
spikes), so I'm not buying the "Anything lower than 100 FPS is crap"
argument since it's a steady 49 fps.
Is there any Valve documentation about this, not what someone
thinks it is,
but what it's defined as by Valve?
Thanks,

Chris

Are you using -pingboost 1   ?

Try that first

My kernel is the stock mandrake 64 bit kernel.  Would it help
to upgrade
to 2.6.x?

According to the great words of hondaman:


Oh, ok.  Mine is 100.  And let me guess.  The higher the


sys_ticrate,


the higher the cpu usage?


Yes. And if yours is at 100 and you're only getting 50 fps,
then setting
it higher won't increase your frame rate. Leave sys_ticrate alone and
check your kernel settings.
