Oh comon

I got x3 RX Vegas 64 Nitro+ and when I try 1.7.1 I got 200H/s less than 1.7.0..
Could you please share you config ??
My config in 1.7.0 :
{
"cryptonight_type" : "normalv8",
"intensity" : 124,
"double_threads" : true
}
GPU0: Radeon RX Vega [gfx900] [8176 MB][I: 124.0][W: 16][T: 2][F: 4][A: 0][BUS: 9]
GPU1: Radeon RX Vega [gfx900] [8176 MB][I: 124.0][W: 16][T: 2][F: 4][A: 0][BUS: 13]
GPU2: Radeon RX Vega [gfx900] [8176 MB][I: 124.0][W: 16][T: 2][F: 4][A: 0][BUS: 3]
Here is a table where you can see the exact information.
