Sometimes. Sometimes it's good and sometimes it's choppy and then other times it just freezes on finished file playback.

When you assemble video in an editor, the video isn't made until you let the software render the whole video and export it as one cohesive clip. Until then, when you hit "play" on the editing screen, your computer has to rummage around all your clips and assemble the video on the fly. Stuttering here is normal. Faster computers speeds up this "preview" playback, but nobody expects it to be smooth.
From what I see on you screen right now, I see that your CPU is pegging 100% while you have a the video preview and storyboard up. This looks like you are right in the middle of editing, and trying to watch the video as you make it. Stuttering and slow downs here are perfectly normal.
Sometimes it plays in a choppy manner, sometimes it just hangs like above. It never plays nicely while editing.
Yeeeah. I think it's about managing expectations now.
Camtasia is an editor. It's not really meant for playback. When you open a clip in Camtasia to look at, Camtasia should be doing a bunch of things in the background with that clip to prepare it for use in a new project. This sucks up a ton of CPU power and RAM, but is rather normal.
If you are just trying to watch a video that you've made, you should be using a media player like VLC. If you are just navigating preview files in your media bin, expect lag as every time you open a file from your media bin, Camtasia is likely making a copy of it in a cache file and getting ready for the clip to be edited.
For me, on Adobe Premiere, the first time I scrub through a clip in my media browser, I don't often get smooth playback. After I've trimmed up some clips together on the timeline, the preview playback is smooth unless I've modified the clip in any way--for instance, if I applied any color effects, the computer will slow down as it gets to that part in the preview video. When it gets there, the computer pegs the CPU as it tries to colorize every individual frame for me in real time, and ends up stuttering or slowing down. In the end, after I've completely rendered the video, playback in VLC is smooth.
