  1. want to point out that i don't have SIP enabled and the drivers installed fine, i have no gfx lag, boot or speed problems just artifacts after a while and mostly they appear on web images and gfx programs (i'm using OsxAptioFixDrv-64.efi with clover 2.4k r4391 and it happens with the official apple nvidia drivers as well). I made a display override with my display edid as well in case that is the problem with the glitches but didn't help. To test for glitches I run Geekbench Compute Metal benchmark and while running I load a pdf with text and images (macOS preview program) and scroll up and down ... after few seconds it shows glitches in images.
  2. just upgraded from Yosemite... and with the 387. version I have glitches after a while (10.13.3 - 17D47) with my gtx 660, hope they fix this

    hello @tluck, can you provide Clover r4052 installer? to install the clover scripts on hdd because they are missing from the zip, thank you!

    i don't know why but i removed the vga kext patch from clover and made again AppleBacklightInjector.kext with the Rehabman script, and now the brightness works as it should before and after sleep (in clover i have display fix and PNLF fix enable).

    yes all is perfect but brightness before sleep , maybe it has to do with PNLF or something in the dsdt , but i change it like yours now and still the same. the only thing i see different in dsdt is that you have the "fix - set OS to WIN7" i dont have that , i have an old method Windows 2001

    thx tluck , i just patched my old dsdt to know what i'm doing (it had only sleep issues now its ok, the gfx seems faster too and more responsive). Now 5 brightness levels does not do anything before sleep but after sleep all work, added the vga kext patch on clover and nothing changed but i did not change the patch like you said above , i convert these numbers to base64 and replace the ones in config ? seems i must patch the kext directly but its better with clover on the fly
