After running for a while RX Vega drops from slightly above 2000H/s to 1700-1800, not sure if it's heat soaking or power management but temperature does not look high and I would expect power management to kick in sooner and raising power in Wattman rises hashrate a bit but nowhere near the initial 2000. Shutting down miner and restarting it's back to 2000. I have lowered settings a bit and now it's running in 1930-50 range at 250W and so far does not seem to drop hashrate over time.
Also tried the miner on my RX4**/5** rig but it does not work,  it's been designed specifically for Vega cards. Need to have a look around if there is something better than the one that comes with NiceHash for RX4**/5** cards.
Edit: I think I found when Vega drops hashrate. If I switch off monitor it keeps mining at the full hashrate, when I switch it on it drops to 1500 temporarily, then goes to 1700 but never fully recovers to 1950, only way is to restart miner.
