Thank you very much for your answers!
I have 4 GB RAM, should be enough, right?
when i registered at Tanki, i click on play, then a scenario is loaded, during this time the CPU is used to 100% (!!), RAM to 30 to maximum 50%;
when the scenario is loaded and the game is running (7 minutes) the CPU goes down to 70 to 80%, RAM always stays at 30 to 50%
other applications are all off

How do I enlarge my swap file? Are the files (...firefox - contentproc - childID 1), the swap files ?
