You need to modify the configuration on your main page and help page.
When using ethminer there are two switches. the -G you mention is only for AMD based GPUs best performance.
changing the -G to
-U is the configuration for Nvidia GPUs. I think some NOOBs are confused by this. This is only for use with ethminer and not with claymore.
Best nvidia GTX 1050/60/70/80 config is as follows
setx GPU_FORCE_64BIT_PTR 0
setx GPU_MAX_HEAP_SIZE 100
setx GPU_USE_SYNC_OBJECTS 1
setx GPU_MAX_ALLOC_PERCENT 100
setx GPU_SINGLE_ALLOC_PERCENT 100
ethminer --farm-recheck 500 -U -F

I'm using claymore currently, avg hash ~26MH/s. If switching to ethminer, any idea how much % jump in hashrate?
