I'm mining veil and I will show you my screenshot hashrate with GTX 1080ti below.

As you can see I'm currently have around 33 hashrate but I just set the clock for much efficiency that is why the watt is low compared to stock clock.
This is not accurate and sometimes the hashrate shows 45 because the hashrate is depends on the hash order.
If you are planning to mine veil try to play the intensity 19 to 23 but for my GTX 1080ti I set it to intensity 23.
