Quick Question re maxfps and rate
« on: February 07, 2012, 11:11:24 PM »
My apologies if this has been done to death! ;)

I'm just curious as to what people are using nowadays for their cl_maxfps and rate settings?

Currently on my cable connection, using r1q2, I'm using cl_maxfps 40 and rate 10000.

I ask mainly because I've been getting some pjod lately on the servers and I'm wondering if it's my settings or if I just have a crappy connection.

I ask mainly because I've been getting some pjod lately on the servers and I'm wondering if it's my settings or if I just have a crappy connection.

For initial troubleshooting, try:

  netgraph 1
  cl_drawfps 1


If you ever see yellow lines in your netgraph, that would indicate rate-clipping.  With a rate of 10000, that should be unlikely except on crowded small maps.

Red lines indicate packetloss, which cause 'hitches' in the gameplay.  In most cases there's not a lot one can do to lessen occasional packetloss if it's occurring.  However if the packetloss is really bad (tons of red lines) there's a better chance of getting your ISP (and/or the tastyspleen-side network provider) to look into it.

Sloping or saw-tooth green areas also indicate a network problem; these can sometimes be mitigated by lowering the outgoing (client->server) packet rate.  However, your cl_maxfps 40 is already rather low.  (I use 125.)

Finally, if your video frame rate is choppy (i.e. the cl_drawfps number on the screen is varying greatly from moment to moment) that would tend to indicate a graphics problem rather than a network problem.

BTW, what values do you have set for the following: cl_async ; r_maxfps ?

Haven't seen any yellow lines at all, so that's good. ;)

I got it once playing this morning on TS dm server while playing on q2dm1. I noticed three big green spikes and a single red line. I suspect TBH judging from this that it's to do with my Internet connection which can be very unstable sometimes. Phacking Mediacom. :P

I used to use 30. I guess that's what comes of spending the first eight years of Q2 playing on a dial-up connection. I was used to me and most of the people I played with being HPBs so I have had my cl_maxfps set low. Never wanted to flood my own connection or anyone else's! Maybe I'll set it higher and see if that makes a difference.

My FPS is okay - timedemo on crusher.dm2 gives me framerates in the 60s and 70s while I get up to 145 on demo1.dm2. I did get over 250 at one point but I'm not sure what I did to GET that. Probably not having Firefox and SETI@Home running in the background. ;)

cl_async is 1; r_maxfps is 125.
