Old issue that dates back to Eldarscrolls Oblivion, UI Performance hit when trying to save the game when having too many seperate saves already. I am finding that if I have more than 10 hard saves[Not quicksaves] the UI will slow to a crawl with both keyboard and mouse input when trying to select a save to overwrite or to make a new one.

Please report it in this thread so it can be logged correctly: http://www.gamesas.com/topic/1544248-bug-report-index-pc/
