Eric's correct. All flushes are beam synced. Different graphics drivers
have different implementation of the beamsync functionality. e.g. flush
when beam is not in region of update, flush when beam is below region
of update or even vbl sync'ing. The second is very likely going to
cause slow downs as you move closer to the bottom of the screen.

Do you know any workaround to fix slowdown?

None offhand.
