GTX 660 glitch issue with MacOS High Sierra 10.13

[LeBaldi]

I noticed that when de VRAM stuck on midle clock (mine in 1600mhz)... the glitches apears... but unfortunately i didnt locate this frequency to stick with maximum clock (its 3002mhz in my case)

Maybe if the frequencies can be fixed inside some kext, I don't have a clue. I don't want to quote any developer, but for sure someone have a clue about that (at least for testing purposes).

Well... I founded where to fixed the clock of VRAM... and I did... BUT... even so... becomes the glitch... BUT AGAIN... become to be different... it glitch only in the effect of maximize or open and close photo for exemple... but as soon as the effect ends... the artifacts gone away

So... defenely it is problem with the clock steps

I will test now with fixed VRAM and GPU clock to seed what happens

Is it still working OK?

Unfortunately no. The problems are less frequent and the machine is basically usable for my purposes, but glitching does still occur.

WEG recently rolled together all the different graphicsfixup kexts into a single kexts. That being said, someone posted that they were getting the black screen bug on a 660.

I can no longer easily test this card since i have replaced my 660 with a HD 5770 that was lying around.

It's because the project seems quite active and because of this:

• Fixes NVIDIA GPU interface stuttering on 10.13 (official and web drivers)

I tested here with all clock fixed and nothing... fixed voltage and clock and still glitch... but not permanent as i comment previewsly

I just tested WhateverGreen with Mojave public beta 2. The artifacts seemed to start showing much faster, but seemed slightly less intrusive for some things. Previously when the artifacts would appear, the menubar text and drop down menus would be unreadable, but so far that hasn't been the case with WhateverGreen. The artifacts aren't staying on the menubar permanently, but they do seem to be permanent on the drop down menus. I can watch a fullscreen youtube video in Safari without artifacts (although they do show up while the video is switching to fullscreen). I only tested for maybe 15 minutes so it's possible that it could get worse. For me, any amount of artifacts is unacceptable so I wasn't interested in testing any further.

I've setup an High Sierra installation to test it. It seems the glitches are far less than usual for me. It happens slightly less, and it's exactly the same situation you described. Just for the record, here's the setup I've tested so far:

MacOS High Sierra 10.13.6, CUDA Driver 396.148, Nvidia Drivers 387.10.10.10.40.105, WhateverGreen 1.2.0.

Update: I was testing some stuff here. If you keep a game fullscreen, the glitches doesn't appears anymore, but is just a matter of changing to window mode and the window will be entirely glitched. I've close the window and there's no glitches anywhere else. In other hand, if I open youtube in Safari, changes to fullscreen to window again, is a matter of minutes to glitching and transmit to menus and other windows.
