Anybody noticed some lags after wake from sleep with Radeon cards?
@Skyfoxxp ?
@dandelionclock ? Not that obvious unless you make a benchtest like Basemark (metal), GFXBench (metal), Cinebench (OpenGL) or GLView (OpenGL). Scores are dropping by half... Big Sur, Mojave or Monterey.
However, OpenCL benchs (GeekBench free, LuxMark) don't show any difference before or after sleep. The only way to regain performance is to reboot... and no sleep!
Now running a lowly GT740 and no benchtest difference before or after sleep??? NVidia seems unaffected.
It's like the combination of "my machine" Hackintoshed and the Radeon Polaris cards is buggy.
I will have to try the UHD 630. My only brief try gave me lit screen but no image. Surely some frammebuffer tailoring as I use two Acer LCD's with DVI output only. So, I have to use, for my RX460, a DVI to HDMI cable for one of them. Unfortunately, I have to also use a DVI to DP adapter for the other screen with the UHD 630.
I would guess however that there would be no performance lag after sleep.
My other build, Z390 with an RX560, doesn't exhibit this behavior.
I've tried everything:
- clean install of Mojave, Big Sur. Lags after wake;
- replacing RAM sticks with spares, same;
- booting with bare minimum stuff, only the hack SSD, the GPU, Keyboard and mouse, same!
- a different LCD, mouse and keyboard, no change!
- downgrading BIOS from 1.1.26 to 1.1.24 and even, 1.1.15, no difference;
- different versions of kexts, ACPI patches, bootloaders (Clover, OC 0.6.9, 0.8.3, 0.8.5, 0.8.8), no dice!
Performance is fine before or after sleep in Windows 11 with the RX460 and also an WX5100 (this one, being also Polaris based, behave the same and lags in benches and visually after sleep in MacOS).
I've ordered a cheap HP RX5500 from EvilBay but I doubt I'll face the same...
That's really a strange one as I see users in this thread with RX580 or RX570 and you do not seem to suffer this bug.
Remember, it's not that obvious until you test bench the card after sleep...
Not a lot of Hackintosh builds on the XPS 8930 documented on the web except here.
Thanks!
