Diff 2 explains perfectly why verters (and probably a couple of other pools) is so bad at finding blocks compared to the reported hashrate thrown at it. Verters is using diff 1 but accepts diff 2 shares as well while it shouldn't. Meaning that miners using -diff 2 have twice the reported hashrate and get paid twice as much at the expense of diff 1 miners.
Meanwhile I'd guess nicehash is both working with and require diff 2 by default to be in sync with ccminer.
So as usual, different pools use different configs and most of them doesn't understand the implications of their difficulty setting but change them anyway.
Which is why serious miners should always do some calculations based on nethashrate and difficulty to estimate how many coins they should be earning and compare that to what the different pools are paying. Or people could just always solomine to keep things simple.
Lyra2rev2:
750ti: 4750kh/s reported by ccminer rlz60
But only 2500 - 2700 reported by nicehash after some hours
Who's correct ?
--diff 2 (and no it isn't a good idea to make it as default... for reasons explained on vtc thread...)750ti: 4750kh/s reported by ccminer rlz60

Just tested --diff 2 at Nicehash lots of rejects but --diff 1 no rejects. What does this mean?
I don't or hadn't been using the -diff flag, actually using it seems to lower my hash rate shown in the miner software.
So I removed it. Was more or less just a test anyways.
but you need to check what hashrate you get, and if it is smaller by a factor 2 report to them
Well I must say I'm not the sharpest tack in the box lol and do not quite understand much of this hash readings vs the miner vs the pool
with nicehash. what I see there is this:
Speed accepted
7.0990 0.0000 (0.00%) 0.02000000 8
what the miner shows me is this:
accepted: 160/160 (100.00%), 10103 khash/s yay!!!
accepted: 161/161 (100.00%), 10109 khash/s yay!!!
Edit: now it showing this: 10.8020 at nicehash, this jumps around quite a bit from time to time.
Miner stays about the same most of the time give or take +10 -10
My AMD cards and sgminer are even more confusing lol
sgminer showing 1.55Mh/s per card w/ 2x AMD 270 non x cards nicehash showing 3.5210
