Moderators Jake Lo Posted March 24, 2018 Moderators Share Posted March 24, 2018 You could try creating a new partition and install Sierra on it to see. Link to comment Share on other sites More sharing options...

Moderators Jake Lo Posted March 25, 2018 Moderators Share Posted March 25, 2018 If the patches are not working, you'll need to add Lilu + IntelGraphicsDVMTFixup Link to comment Share on other sites More sharing options...
shania Posted March 26, 2018 Share Posted March 26, 2018 With Lilu + IntelGraphicsDVMTFixup system works fine at 1920 no issues but I dont get 4k. According to rehabman I have to work on preallocation dvmt for my graphic 530. And again I will have same issues for Sierra I have to sort this issue to get full 4k acceleration. He said I was patching wrong 0x795 @ 0x3, but he thinks that I am now on right track to get it sorted my 4k. see below his comment. But 0x3 seems not valid for 0x795. 64mb is 0x2.Note that there can be values that are undocumented/not listed in IFR. Do you think I have to runsetup_var 0x796 0x1 orsetup_var 0x796 0x2 orsetup_var 0x796 0x3 Thanks in advance. Link to comment Share on other sites More sharing options...
