Laggy game whils running Mumble in Linux

[zogeln]

Hey,

i searched 2 days without any solutions so i hope i get some help here. I am new to Linux (ubuntu 9.10) and i play Urban Terror. I have a pretty good pc (Core 2 Duo 2 Ghz, 3 gig Ram) and play on highest FPS with no problems.

But when I start Mumble the game starts laggin. The FPS do not go down. On Mumble IRC they told me to turn off overlay - what i did without any improving. Even my Ping is steady no matter if I run Mumble or not. This error ocours with version 1.1.7 and 1.2.2 which i just upgraded today.

I basically went through all settigns you can do on Mumble and tried if it improves but it never did.

Thanks in advance.

So neither your ping nor your FPS change?

But it's lagging? Not juddering?

How's your internet connection/bandwidth? Enough?

Well it is hard to explain maybe laggy is the wrong word. It stotters when i turn my head in game. But Ping and FPS are steady. My connection is 16.3xx kbit down and 1.024 upload. The Ping in game is 40, Mumble ping is 33.

If you are using Urban Terror based on the ioQuake3 engine, then mumble will try to gather positional information about your in-game player. Information about positional audio can be find here. Try turning positional audio off and see if that helps.
