unfortunately it is a known "bug". java - eats resources which in turn effects fps, you can upgrade your pc for possible "fix" and it appears to get worse as friends go off/online or indeed join games, turn off notifications to help a little. however that is not full proof...

removing any extensions that you may have will also assist to some extent.

Yes, it's a known issue from early closed beta, I don't think a rational workaround exists, except for trimming your friend list.

Stermy allegedly stopped adding people that are not his duel partners because of this.

when I was on "low-end" pc, these was a big freezes, BIG! I had like 3-4 friends max in my FL. Now with "med-end" pc I don't feel freezes, but I guess "micro" still exist..

Thx for your answers. I didnt know if it's because of this or because I changed to qlprism yesterday. But as it really bothers me, I will have to delete most ppl from my friendlist.

Good thing is, there aren't THAT many tdm servers populated at the same time anyway, so I will find the guys nevertheless..

before you go ahead and remove a lot... try remove those with strange characters in them 1st ;)

too late.. only 5 or 6 left and microstuttering is nearly gone :)

That's a strange problem. My computer is very low end and a have a huge friendlist but I don't have this issue.

So my recommendation for everyone would be to add people to their friendlist without consideration for this until they get problems with it, because they might never have any.

Nope, it got fixed afaik(though i never had any lag myself and i got 200+ buddies i guess)
There was a problem some time ago - when someone went online/offline and cg_lastmsg was changed to "<QUAKE LIVE> ^5blablabla^7 has gone offline." due to that and QL was writing a config every time that happened which caused a microlag, especially for those who use HDD. This problem got fixed some time ago and there shouldn't be lag anymore.

Nope, it got fixed

They are not really your friends, dump them and take control of your frames per second.

No one is worth dropping frames for...
