ioquake3 seems to be using 100% CPU all the time. Is there anyway to stop this? Even on the menus CPU is 100%. I have a Brix and playing the game is not good for the CPU.
Upgrade to a test build to not use 100% CPU. For reference, setting the console variable com_busyWait to 1 will restore 100% CPU usage in case you want to use a laptop as a space heater.
