Steam Problem: Steam uses 50% of the CPU time on Dual Core systems

Please follow the instructions below to set Steam to free up resources by using only one processor:

1. Launch the Steam client
2. Press CTRL + ALT + DEL simultaneously to open the Task Manager
3. Right-click on Steam.exe in the Processes tab
4. Select Set Affinity
5. De-select one of the processors - i.e. Uncheck CPU1, leaving only CPU0 checked
6. Apply the setting and check the CPU Usage under the Performance tab to confirm the issue has been corrected
