VDA on RX580

I just discovered my computer has a problem. When using boot-arg "shikigva = 128 and shiki-id = Mac-7BA5B2D9E42DDD94" to turn on acceleration for vga rx580, the GB5 score is 31k. While not using the other two boot-args, the GB5 score is 46k, and of course it will lose acceleration.

How should I handle this problem? if you can turn on full acceleration and the GB5 score is not too much difference (up to more than 10k points), it is still great.

I’m using SMBIOS iMac19,1 | i5-9400F | RX 580 | b365m asrock pg4
