Is the hashrate display broken for VECTORS4? Running VEC2/AGG10/WS256 I get ~626MH at 1080/366 (about 10 mh/s less than diablo, not bad!).
If I use VEC4 my hashrate display doubles - ~1.22GH/s. I wish this wasn't a bug or something

Yes, I see this too at stock (1.09Gh v4 agg12). Although, shares are accepted..... gonna wait to see what my site says actual shares are
UPDATE: Actual Hashrate is about the same as vectors2. Seems like a reporting issue.
