Think you have to use -d 0,1 to specify the devices in this beta.

Same here.

I'm also getting around +400 Kh/s on my 7790 and but I'm getting an extra +600 on my 270.  I didn't make any changes to my config.
Here's my config for my 270

"api-allow" : "W:127.0.0.1,W:192.168.0.0/24",
"api-listen" : true,
"api-mcast-port" : "4028",
"api-port" : "4028",
"expiry" : "28",
"kernel-path" : "/usr/local/bin",
"failover-only" : true,
"log" : "5",
"queue" : "1",
"scan-time" : "7",
"gpu-threads" : "2",
"gpu-dyninterval" : "7",
"gpu-engine" : "1111-1111",
"gpu-fan" : "70-70",
"gpu-memclock" : "1500",
"intensity" : "18",
"kernel" : "x11mod",
"temp-hysteresis" : "3",
"worksize" : "128",
"shaders" : "1280",
"thread-concurrency" : "5121",
"lookup-gap" : "2",
"failover-switch-delay" : "60",
"tcp-keepalive" : "30"

With this I'm getting 2.72 MH/s now and was only getting 2.1 MH/s

Is there something wrong with the difficulty?  Ever since the problems with the X11/X13 yesterday, my difficulty settings are being ignored.  I've set d=0.01 but difficulty stays at 0.04.
I've tried changing my difficulty but it stays at 0.04.

I tried it and it has been stable for 1.5 hrs with about 6% increase in hashrate.
Excellent work.
