With which MPlayer version? I think there were some improvements a few
months ago.
But yes, frequently changing subtitles can be an issue.
Sometimes slightly adjusting the size of the subtitles can help,
but is a bit tricky to do.
I'll give it a try later, but I don't know if running it on a desktop
will help much.
You could try running perf record/perf report.
There is also the option of trying the OpenSource driver, which has
the advantage that you can try -vo vdpau which also provides
full-resolution subtitles but using a completely different approach
(though VDPAU still is a bit buggy on AMD, even with the latest of
everything).
