That's why I asked too because what one person thinks is bad is acceptable to another person. Quartz is far from perfect but sometimes people expect it to be flawless.Is there anyone can make a video to illustrate how the UI lag look like? My cMP has nothing top of the line (as per my signature). It's just all normal (and consider low cost) upgrade nowadays, but I didn't realise any UI lag that can affect my work flow.
Are you using NVIDIA web drivers with your GTX680 or just native macOS drivers?Same issue on my 5,1, 3.33, 256gb ssd, 3tb hd, mac gtx 680. Sierra was awful, exactly as you said. Got somewhat better after indexing, but still bad. I tried everything on just about all websites looking for help. Had to go back to El Capitan, much better but now my internet speed is glacial, I wonder if the update fried my ethernet card. Going to try a new one tonight.
Go back to El Capitan, all the speed and snapiness comes back.I have no answer; I'm just writing to commiserate. The frustrating and at times infuriating UI lag is what has been slowly killing my otherwise-healthy 3,1. Death by a thousand lags. 🙁

+1 To this. Try a clean install, especially if you have been upgrading over many OSes.All I can say is many, many years ago with my 2008 my "seasoned" system that I had gone through multiple OS upgrades with suddenly became laggy to the point of being unusable. I tried in vain to identify the culprit. I performed both a dirty OS reinstall and a clean OS install (with migration) but the problem persisted. The only way I found to resolve the issue was to do a clean install of the OS, followed by a clean install of all apps: I did no migration whatsoever of existing apps and settings.
Painful it was as I've never had to do that with OS X; but since then, I've had to resort to starting completely from scratch a couple times, the last time of which I believe was when I was using El Capitan...

is that 128GB of ram? (have there been problems with to much ram?)
iv seen slow down from to little room left on the boot drive.
Since no one post any video to illustrate how bad the UI is. I just made a short video to show the UI performance on my cMP. So now, we can make comment base on the same video, same standard.
Mac Pro 5,1, W3690, R9 380 4GB (as per my signature), the CPU was under stress (about 90% usage on video encoding) when I capturing this video. But that generally doesn't affect the UI performance. And a Mac Pro suppose to be busy all the time anyway. So, I capture the video now, rather than wait until it has idle time.
The focus of this video is on the UI smoothness. Therefore, I use my iPhone to capture the screen rather than using Quicktime to capture the screen (which may introduce UI lag, or unable to capture everything at 60FPS). And I only use 720P to make sure the capture is smooth, which also intentionally make the details hard to read. Please only focus on the UI smoothness.
This is what I generally have, and it looks OK to me. So, please feel free to comment if it's more of less the same on your cMP. If yes, which part (e.g. which second on the video) shows the "lag" etc. May be just I am too casual about the UI, and don't care it.
Also, if you want me to test any UI performance for comparison, please let me know. However, please tell me the exact procedure on how to achieve that. e.g. I can't quite remember what is Expose, I think we only have Mission Control now. So, please tell me the exact UI / function that you are looking for.
That's good but let's also remember that different applications use different SDK. Some front end are accelerated differently from other front ends.
The only two apps that I which I see sluggish resize (for example) are Logic Pro and Scrivener. You would think the second app would be responsive because it looks so simple but if you try to resize columns or a window on the newest Macs you will see it's kinda bad. Download the demo and try a test on different machines.
