When making a Skype video call with a Logitech C600 webcam the video received on the other end often freezes. The local computer is has a single core AMD processor. The video being received from the other computer (Windows7 Intel T2250 @ 1.75 GHz) using the same webcam appears fine.
I suspect the issue is Skype trying to send video at higher a resolution and/or frame rate than the local processor can support.
How can I force Skype to use a lower resolution to see if that improves the video output?
There doesn't appear to be an option to adjust this under Tools > Options > Video settings.
