I've been trying to capture GE navigation movements (screen capture of GE zoom eg.) with mized results.
I maximize the cache sizes and run the zoom several times to note consistent smooth flow in GE before running screen record with Camtasia. However, screen record results are often a bit to quite choppy.
I have a Quad core processor and AMD 7970 GPU so the hardware should be up to the task. My results do seem a bit worse (?) with hardware acceleration disabled.
Capture size also does not seem to make a difference - whether recording at full screen (2560x1600) or smaller windows.
