Fala @MaLd0n,

 

Como sei (Need change to correct "ATY,xxxxx" for your GPU) para minha Vega64?

[MaLd0n]

não sei se a vega foi afetada pelo update

Realmente num to sentindo lentidão não. Vou passar um benchmark

[tiagopreto]

@MaLd0n, ao entrar no hack depois de uns 3min o sistema fica congelado. Eu consigo fazer o processo a partir do windows acessando a EFI do hack?

[Emilio P. Egido]

@MaLd0n

A série 6600 tem que usar framebuffer Henbury em vez de Deepbay? Eu digo isso porque em AMDRadeonX6000Framebuffer.kext (Info.plist) a parte referida ao AMDRadeonNavi23Controller leva ATY, Henbury.

@Emilio P. Egido, faz um teste e me diz que acerto no tópico. 

[Emilio P. Egido]

@MaLd0n

Eu tentei todos os 2 framebuffer, Henbury e Deepbay, aparentemente o sistema funciona bem com ambos, pelo menos até onde eu pude ver.
Com Henbury, o recurso ZeroRPM dos ventiladores da placa gráfica (RX 6600 XT) é desativado, os ventiladores estão funcionando o tempo todo (ruído de volume muito baixo) e a temperatura da GPU cai 10-15 respecto em relação à usual sem este patch.
Com Deepbay isso não acontece.

[jonasw8]

É necessário ter ambos os patch na DSDT e o patch na config.plist ou apenas um deles serve?

yes

is not perfect for now in some cases some problems stay there

wallpaper is just cache i think

yes

173489 is low score? 😅

metal score i think should be around +200K as some reference on tonymac users.

opencl in windows at same pc hits 160K

P.S. On the other hand Idle GPU temperature was decreased to 40C from 55C Idle values.

P.S 2 - Weird but metal score now around 150K after first test and several tries on 12.3 🤯
