kctony Posted May 14, 2018 Share Posted May 14, 2018 Hi there, I have installed my hackintosh on pc with the following config. ASUS z270m, AMD HD 7870, i7-7700k. Following the guides posted on the links below, I managed to get my system up and running. However, huge problem occurs when I try to playback big videos. https://hackintosher.com/guides/hackintosh-amd-graphics-cards-sierra-10-12-6/https://hackintosher.com/guides/fix-rendering-issues-fcpx-high-sierra/ I have followed these guides to try and find a solution but nil help. Please advise if there is anything else I can try? attached please find the config.plist of my efi. Thanks heaps! config.plist Link to comment https://www.insanelymac.com/forum/topic/334083-choppy-4k-video-playback-and-preview/ Share on other sites More sharing options...

kctony Posted May 14, 2018 Author Share Posted May 14, 2018 (edited) https://www98.zippyshare.com/v/jVehRkEq/file.html One thing of notice is, if the file I am playing back is smaller. It is ok... Audio is somehow disabled with your config.plist.

kctony Posted May 14, 2018 Author Share Posted May 14, 2018 (edited) Any ideas guys....? Everything works great... just this to fix.... i am pretty stuck. I can playback small mp4 files but anything bigger than say 1GB is a struggle. but it suddenly occurs to me that there may be a problem with my COSAIR Vengence memory because the activity monitor really doesn’t show that I am using much of my 32GB. They are recognised in system status though.

kctony Posted May 14, 2018 Author Share Posted May 14, 2018 (edited) Sorry... I am too noob to understand what I have to do here to fix it. Could you elaborate further? Could anyone please spare a minute and help.... zzz I tried to change to different system config. None of the Mac Pro seems to work.

kctony Posted May 15, 2018 Author Share Posted May 15, 2018 (edited) Yes I appreciate what he is doing. But I don’t understand his last instruction. Lol Edit: i did a bit research regarding DSDT inject. Found videos like this for older OSX. Is this what should I try to apply? Could you elaborate further on this regard please? Cheers!

kctony Posted May 15, 2018 Author Share Posted May 15, 2018 (edited) I have both the shiki kext and skikigva flag set to -shikigva=4 for AMD and BIOS settings have both GPU enabled already. DVM set to 128GB. Shiki kext in both /L/E and CLOVER/kext/others.

MaLd0n Posted May 15, 2018 Share Posted May 15, 2018 for me only shikigva=60 work, RX580, check a correct flag Link to comment https://www.insanelymac.com/forum/topic/334083-choppy-4k-video-playback-and-preview/#findComment-2613689 Share on other sites More sharing options...
kctony Posted May 16, 2018 Author Share Posted May 16, 2018 (edited) I tried to use 1,4,12,16,60. None of the numbers seem to make a big difference. Interestingly though would it be a problem of RAM? Because when I play back, the memory hasn’t been cached in the activity monitor. Edit: For what it is worth, I managed to get a rx580 sapphire nitro+ to test it out to see if it is the problem of my dGPU. Same result. It stops at roughly around about 12 seconds into the 1.6GB mp4.
