![]() ![]() So the one problem I have no workaround/solution for is #2 - missing HW encode/decode. And problem #3 only happens sometimes, and once I have it fixed I can simply not turn off the PC to avoid it happening again. It is quite annoying and slow on the X58/Vega 64 system, because I must boot without any monitors connected, but it does work. Right now I have a workaround for problem #1, ie I can sleep & wake to get all monitors working. I have posted many times on InsanelyMac forum, but no-one seems able to help. I am sorry for posting so many issues here, but I have spent literally many days trying to solve these problems, and have got nowhere. Nothing I have ever tried can resolve any of these issues. I have tested with every possible combination of graphical settings I know about - WEG on/off InjectATI on/off every possible WEG option Clover Framebuffer patching and more. ![]() On H77 system I am also using WEG 1.3.2, but i don't know if this is changing anything I get same issues with and without WEG. Today it took me literally 2 hours of rebooting to get it to come up in the X58 system I am using WEG 1.3.2 and have InjectATI set in Clover I need both of these, otherwise I did not get full performance from the Vega 64 in Geekbench (without WEG+InjectATI: 148k Geekbench 4 Compute score with WEG+InjectATI: 205k GB4 Compute.) I run WEG with -raddvi and -rad24 settings. I don't yet know what causes it to sometimes work, sometimes not. But with Vega 64 in macOS, sometimes it connects at sometimes it's and sometimes it's 2840x1080 60. On X58 with RX Vega 64 only: my 4K monitor sometimes won't connect at I am using Displayport 1.2 cable, and in Windows 10 it's fine, and also was fine on my older R9 280X GPU. Also, playing a 4K video in eg VLC will show very high CPU usage (300-500%) This is shown by apps such as Video Converter Pro and MacX Video Converter Pro. On both systems: I have no HW h264/h265 encode/decode. With this done, there are no Console errors, and I can put the system to sleep, then wake it, then I will have a picture on all monitors. The only way I can sleep is by booting with no monitors connected to any GPU port. On RX Vega 64 on X58, this problem is even worse: I get black screen on all monitors, and trying to sleep the system will cause it to hang.After first sleep, I get a picture on all monitors. To resolve these issues, I must sleep & wake. Console log is full of errors, in particular "CRITICAL ERROR : VBLANK interrupt has not been generated in time!", and Activity Monitor shows 100% CPU on kernel. On both systems: from boot, I get black screen on most or all GPU ports.On both these systems I have problems with AMD graphics: No active iGPU (it's Intel 2500, not supported). One: X58, Xeon X5670, legacy boot (Clover R4945), AMD RX Vega 64 8GB GPU (Gigabyte OC model). ![]()
