I tested LTSP a bit on an empty 100mbps lan, with a video playing choppy (tried youtube videos in Firefox and some *small* 320x mpeg). Watched the bandwidth usage on the router and it was < 1mbps so network isn't an issue.
The server and the test client were both very high power/memory (not a 'thin' client at all). Memory usage and CPU usage on both were fine (verified LTSP usage w/ local root login).
The client had the Nvidia drivers enabled, though also using the open-source driver gave similar result.
It appears the problem is completely unrelated to hardware, as mentioned. Perhaps the latency on the network (I don't know this networks latency, though the client and server are in the same room with only 1 switch between them) is large enough to cause a problem, but at 30fps I wouldn't think that is the case.
