Is Nicehash miner v0.3a slower than 0.2a?

Using 0.3a I'm showing an incredibly higher I/s rate, but my Sols/s is about 30% of what I got with 0.2a. Is this just my machine or anyone else?

they need to fix AMD on this miner, its really bad

I know AMD support is experimental but I'm using an NVIDIA card and it seems to be a lot slower than 0.2a unless there's something I don't understand.
