GTX 1060 performance on 10.13 High Sierra

[acantril]

I'm glad i found this i thought i was going insane. I get the pauses on the webpage above too.
Also, when doing keynote work.. with animations, there is stuttering rhere too.
I use Imac17,1 .. i have a 6700K, Z170a chipset and a GTX 1080ti.
also get no bad performance on macbook pro with AMD.
I have 3 x 4k screens connected,interesting what was said above regarding it being a multiscreen bug.
I have a VEGA64 and a AMD 560?? or 80 i think i can test.

@acantril I look forward to your Vega / 560 / 580 testing. I upgraded to 10.13.2 (nvidia 378.10.10.10.25.102) and can confirm the performance is unchanged. Still stuttery and laggy.

I did try an install of 10.12.6 using the exact same hardware. 0 stutters - which suggests a graphics driver or OS issue.
Intterestingly enough, dragging windows between screens in Sierra is perfect, in HS there is a nasty pause as it moved between.

@acantril yup I know exactly what you're talking about. It's buttery smooth overall broken up by little 0.25-0.5s blips where the entire interface pauses then goes immediately back to smooth again. It's especially noticeable when resizing windows or dragging them from one monitor to the other rapidly.

Woah thats even worse than on my hack.

Gonna update to the latest HS version and try the latest driver.

@xelanaiznac @Killuminati91 at least it's good to hear i'm not alone. I'm not sure why more people aren't talking about this issue. My system is practically unusable since the update to 10.13 and we're all running the same gen Nvidia 10xx pascal cards.

So something even more interesting. My other half has a iMac .. the last model of non retina. Upgraded to High sierra... same performance issues. Tried booting an old sierra install.. 100% perfect. So its 100% something to do with HS .. and the gfx.
V. interesting is that it has a NVIDIA 680MX in it - so i wonder if its a NVIDIA driver issue on HS.

Going to check if the drivers for VEGA 64 are stable'ish .. and try that in my HS install.

Yes, I guess it's a real Apple + Nvidia driver bug, probably related to Metal. This thread has 8 pages of users with real macs containing all manner of Nvidia GPUs and complaining of the same problem. https://discussions.apple.com/thread/8141739
