Just FYI.

I have reference Vega 56 flashed with LC BIOS and I had 1-2sec timeframe spikes with weird GPU utilization fluctuations with every driver past 18.2.1.

Fellows on Guru3D forums recommended to flash BIOS from standard Vega 64 because it seems like AMD changed something for Vega 64 LC in driver 18.2.2 and later and it's causing issues on reference non-LC cards flashed with LC BIOS.

I didn't checked that because I'm rebuilding my custom waterloop, but other guy with same card with LC BIOS confirmed that flash to "standard" non-LC BIOS helped him.
