Maybe just try ProSnooperFx:
http://lookias.worms2d.info/download.phpAt my old slow PC I had lagproblems, too. If you want to use The Wheat Snooper you have to manually change two important settings.
- At Channels and Chat: Click ☑ for don't open windows automatically, hide them to system tray.
- At Game: Hide all Channel windows when u r starting a game.
If all windows r hided and u click minimize the snooper to system tray then the lag because of the snooper stops.
When I installed the newest snooper I had to manually delete the LOG files of the old snooper, because the logs of the newest snooper weren't compatible with the old log system. My CPU for Snooper always got to 99% when I opened it. Took a long time to fix it. GL
