In both version 4 and 5 the updating is done in batches every 50ms (20 fps)

Its quite possible that the changes for Unicode have had a slight impact on performance but I think the biggest impact is probably the word-wrap offset calculations and not really the actual drawing itself.

Comparing both v4 and v5 running side by side processing the same queue with the same settings everything looks identical except that v5 is slightly faster at completing the queue.
