Hi everyone!

I'm new to this forum and to quakeworld but has experienced a problem that i hopefully think someone could help me with.

Problem: When i enter a QW server and my fps (cl_maxfps) is between aprox 150 and below the grafic is lagging (hacking) both when i walk and move the mouse. The mouse movements is normal and smooth however so nothing wrong there.. When i write higher numbers and especially "cl_maxfps 0" this lagg/hack in grafix is gone. This is very annoying and barely playable atm since i play with a LCD @ 75 hz and want around 150 fps or so...

Would be very happy if someone knew what this problem is cuased by..


Cheers and thnx alot

A general rule of thumb when it comes to Quakeworld and chopiness is that you cl_maxfps value and vid_displayfrequency value should be synched.

vid_displayfrequency "75" => cl_maxfps "75" or cl_maxfps "150" (75*2) or cl_maxfps "225" (75*3)
vid_displayfrequency "77" => cl_maxfps "77" or cl_maxfps "154" (77*2) or cl_maxfps "231" (77*3)
etc...

Make sure you have your resolution set to 1280x1024 @ 75hz in Windows too. I thought Hz settings above 60 wouldn't make any difference on a LCD monitor, but i think it affects things too.

Edit
My first tips and a few more can be read at the smooth Quake entry in the QWDrama wiki.

Only one problem Ã…ke, the wiki guide says that you *shouldn't* be using a multiple of 75 if you are using an LCD. Not sure that I agree with that personally but... wikis can be wrong sometimes =)

FPS Limit Fine-Tuning

Especially with LCD devices do not use FPS limit (cl_maxfps) that is a multiplication of your display refresh frequency. For example using 75 Hz display refresh frequency and FPS limit very close to 225 (= 3*75) will most probably lead to tearing of the image.

On my LCD (226bw) 60 and and 75Hz makes a difference, it might not be the same for all LCDs though so you have to try for yourself.

Seriously tearing is nothing, after a month you wont even notice it. :> IMO its far smoother that way than 60hz @ 77fps or something like that.

Heh, for me it has always been the other way around biomass. Even a 1fps change compared to the Hz makes it all choppy.

I wrote that part of the wiki article, since then I heard some users saying the same thing like you here, so now I've edited the article and corrected it.

Doesn't triple buffering cause lag too? The article does not warn about it. The goal should be "responsive" Quake, not just "smooth".
