A update on some issues I've run into.
X11 still seems to have issues with connecting to pools in MM. This is the same problem I listed earlier. Eventually MM will end back up on the right pools, but to start with it'll go to my backup pools first. Where as with SGHMINER it goes right to the proper pool immediately (I dropped in the same exact version I use with the bat file). There has to be something with MM and the way it deals with down pools.
In a nutshell, MultiMiner is launching the executable found on the Process Log screen (available from right-click) with the arguments found there too. There's nothing beyond that MultiMiner is doing. That needs to be the starting point for diagnosing the differences you are seeing.
FWIW I see this problem too if I use DarkcoinSGMiner but SPHSGMiner seems to work better.
I've also seen the "all pools appear to be down" if the right algorithm arguments aren't being passed to the backend miner.
Profitability switching was fucked up for a bit. It started switching itself on randomly even after I turned it off. I seem to have completely disabled it, but it was mining random coins for a fair bit of time (like Doge, which I no longer mine anymore). One machine I thought I fixed went and turned it back on again.
This is a bug that is fixed for 3.0.2, which will be going out pretty soon. Happens when you use Quick Switch.
Edit: it's fixed in the 3.1 preview I linked previously too.
X11 seems to produce worse hash then running the miners in standalone. This is with SGHMINER. Running standalone they'll produce about 15% more hash then using MM and the same exact version of SGHMINER. This is when they're on the same pools and using the same settings.
Same response as up above - please start with the Process Log screen in MultiMiner. MultiMiner is "simply" launching the executable you see there with the arguments you see there. If you stop mining in MultiMiner, you can right-click in the Process Log and click Launch to start the miner directly.
Please use this to compare performance and see what it is specifically causing the difference you are seeing.
If you are seeing different performance simply by clicking the Launch button in MultiMiner specifically, please let me know the executable and arguments.
Thanks very much for the feedback - keep it coming!
