In the Options menu, you can change the update delay to being higher. MySEQ does use some CPU sometimes. If you increase the update delay to 500 msec, that might help some. I wouldn't worry about FPS so much. Even 1 fps, is more than enough to see what is going on in the client.
If you want to learn more about MySEQ, I would recommend reading the release notes. This says alot concerning the features that have been added over time. Reading in the MySEQ section of the boards, also provides alot of insight into the makings of the software too. If I get a few hours this afternoon, I will try to compile together as much info as I can for some sort of manual. But no guarantees.
