However AVIC still doesn't work, though multi-threaded performance did improve around 5%. There was no change in single threaded performance. Remember I'm just using the simple benchmark in CPU-Z, so it's a very rudimentary test. However a 5% jump is significant enough for me to believe it's real. -- You are receiving this mail because: You are watching the assignee of the bug.
