Bro, please share the driver version and hash rate for your vega on Lyra2z.

Lyra2Z hashrate is 1620khs on my vega 56, on Ubuntu 18.04 with AMDGPU Pro PAL driver (https://support.amd.com/en-us/kb-articles/Pages/Radeon-Software-for-Linux-Release-Notes.aspx).
The hashrate on windows should be the same. I tried using newest driver.

Lyra2z somewhat better than the old sgminer by djm34, but still has a way to go compared to mkxminer (https://bitcointalk.org/index.php?topic=2360168.0)
Hope you can do much better Wink

Beta4 release: https://github.com/fancyIX/sgminer-phi2-branch/releases/tag/5.6.1.3.b4. About 40% faster on my rx 580 and vega 56 cards. The speed is improved using pre-built binary kernels. They are only used if you use "-w 256". Please don't delete them otherwise new kernel will be compiled from source code and will be slower than those pre-built kernel. Please help test if interested.

Beta5 release, about 30% faster:

Thanks for the info.
Their algorithm uses 4x4 lyra2, which has already been fully optimized by many miners and is much easier to optimize than 8x8 lyra2.
My miner is good at optimizing 8x8 lyra2, which is much harder, but may not be the best for 4x4 lyra2.

There is a bounty for fastest AMD miner.
