Has anyone gotten this to work for Windows now?

For some reason I'm getting only 1.5MH/s on HD 7850 @1050/1300 core/mem - which is very close to the previous lazybear x11 mod for sph

.bat as below
setx GPU_MAX_ALLOC_PERCENT 100
setx GPU_USE_SYNC_OBJECTS 1
C:\sgminer\sgminer.exe -k x11mod  -o -p -u -I 15 -g 4 -w 128 --lookup-gap 2 --thread-concurrency 8192 --failover-only
