Tip: Slow Chrome, try this

I noticed my Chrome was chugging it after switching to opencore and upgrading to big sur.

I have an i9 and 5700xt, neither which should be a problem, but things just werent as smooth as they were on Clover+Catalina.

Try this:

  1. Go to chrome://flags
  2. Change "GPU Rasterization" to disabled.

For some reasons, and I'm not sure if it's opencore, big sur, or the version of chrome. But disabling GPU Rasterization, really put a stop to some chugging I was experiencing.

Inspiron 5567 / i7-7500U / 12GB RAM / HD620

I just have one problem.... =/

When i turn on my Wi-Fi, my bluetooth goes wild and theres a lot of interference (on bluetooth side) and i cannot use 5G Wi-Fi (returns password incorrect error). With the Wi-Fi on, my Ethernet cable stops working too (i lost my ip and i get an Self-signed ip)

I cant use AirDrop (I didnt test messages or FaceTime, but AppStore works)

But.... everything else is working!! I even uploaded some iOS builds to TestFlight some days ago

Can someone help me fix audio on my dell latitude e6500?

I installed macos high sierra 10.13.6 on dell latitude e6500(intel c2d p8700,4gb ram, nvidia quadro nvs160m,idt92hd71 audio) and everything is fine except audio. I got patched applehda for my idt92hd71 and also got hdaenabler in my efi folder and s/l/e folder. Set layout id in config.plist to 13 which is default by this patched applehda and also applied dsdt patch for idt92hd71 that i read somewhere that i need. It detects audio output and detects when i plugin headphones in but no audio is coming out from speakers or from headphones. How can i fix this?
