It doesn't change anything on my 1080Ti. I have it with 1060, so I use --revA 0 (the 1080Ti is GPU0). I launch the tool before miner, pause 3 sec and launch claymore (or ethminer) : always 37MH/s

if i got it right, -revA need to use in case of 1080 with old memory or smth like that.
try both ways.
1080 ti should work fine without revA
my 1080 works only with revA
my 1080 ti works without revA
