Any news about the Macbook Pro Nvidia GPU lag yet?

It's "fixed". It's definitely better but sometimes i tend to notice a slowdown. But it's good enough for now; at least until Apple updates its driver itself.

Do we need to install the CUDA drivers as well? http://www.nvidia.com/object/macosx-cuda-9.0.222-driver.html

The nvidia drivers alone have improved the performance of my machine, it's usable now at a scaled resolution on my 4K screen.

Edit: unfortunately had to return back to unscaled resolution. At high loads, the system becomes unusable like before. Seems like updated drivers did not fully resolve the issue :(

I noticed Photoshop still triggers lag. It's definitely not fixed, but it does show (significant) improvements for me.

After installing the security fix yesterday, I got "the slows" on my MBP without an external monitor plugged in. I also had just updated to the latest Camtasia - no idea if this was the trigger. But I am tired of this little episode of ineptitude on Apple's part. I did get a update notice from nvidia about newer drivers.... I'll wait for the next dot-release of Mac OS and see how that works. But reversion is probably the best way to go.

Problem exsists on MPB 15" late 2013 (nVidia GT 750 2gb) with 10.13.1.
Tried updated nvidia web driver 378.10.10.10.20.109, no result. Besides with activated 378.10.10.10.20.109 driver after a few hours of work appears strange flickering of windows and strange glitches.

That's sounds strange, if same issue / same symptom appear regardless which driver you are using. Then most likely it's not really driver related.

I am also using a Nvidia GPU in High Sierra (10.13.2 now) with the latest web driver, flawless experience so far. But I am with the tower desktop Mac Pro, and I am running the 1080Ti. So, the newer hardware may help.

However, since the symptoms is driver independent. And seems did't affect the newer GPU. So I suspect may be it's really Metal 2 related. May I know what do you guys see in this page (about Metal support)?

Same as you:



Far from flawless though. Extremely laggy unless I run it in full (tiny text) resolution.

I am now testing in 3840x1080 HiDIP (even though my monitor is a 3840x1080 144Hz monitor. I let the GPU rendering at 7680x2160 144FPS). I can feel that not as smooth as non HiDPI option, but totally acceptable. Will observe if this HiDPI thing is buggy and eat up all VRAM and slow down the whole computer.

Could this be a vram problem when scaling?
[doublepost=1513618950][/doublepost]What was the max external display resolution for those models in that era? I know via hdmi you could do 4K but only 30hz. Not sure about Thunderbolt.
