@Jos Huntjens (Lox) check your system's shortcut keys.

This should be fixed in the latest build.

Same on macOS Mojave !
Macbook Pro Retina Mid 2012
2.3 GHz Intel Core i7
8 GB 1600 MHz DDR3

Closing since we only officially support macOS 10.12 and higher for Blender 2.80 now.

Thanks I'm going to post there!

First, this is not a place for feedback, but for bug reports. Feedback goes here: https://devtalk.blender.org/c/user-feedback

No official roadmap for this at the moment.

I was talking about rendering groups of bsdfs, have them write to (an) intermediate buffer(s) then combining them later
on with a final pass. But you're right, it'd take too much time to just develop let alone maintaining.

For higher texture count we aim at using bindless textures extension on newer hardware. This should fix your second use case.

I am running the latest version of Blender on my MacBook Pro and I still have the same issue, the viewport jumps from smooth to laggy constantly.

Following up, maybe we can branch off and have EEVEE render such materials by doing multiple passes? I may be able to work on this but I'm a rusty in OpenGL and I don't have much knowledge of the Blender's code base.

Any feedback please?

Hello. I am still wait for you to processing for Mac Blender 2.80 BETA

Yes, we will review it and commit a solution for this bug, should not be too long.

Is this patch going to be implemented in the main 2.8 version available for download on the Blender website?. I'm downloading each new build on a daily basis, but so far, the issue with the viewport lag doesn't seem to be fixed yet.

@Furkan (furkan161) I think it’s a pretty normal and OS-independent behavior that it lags a lot when creating a mesh with a large number of elements. D4619 addresses a specific issue in macOS’s presentation path and doesn’t magically make everything faster.

okey i tried D4619 path but it did not worked for me

Increasing the system cursor size a bit in Accessibility > Display options (OSX System preferences) resolves the issue on High Sierra.

Here is a scene that where I am having this problem. The problem seem to be visible only in perspective mode. Not in orthographic mode.

can some one send me the D4619 patched blender 2.8 file, i am having trouble with "make" part.

For me it's the same as LuisG describes.

Hi, same problem here. Viewport rotation, panning and zooming is smooth in 2.79 but lags terribly in 2.8 (with same scene loaded in both). Disabling grid and axis display in Overlays alleviates this problem, but overall it never reaches the smoothness of 2.79

just adding confirmation that i see this lag as well, and it moves very smoothly with

--debug-value 23

@Tomoaki Kawada (yvt) That's some impressive work you did here! Did you try a simpler approach first? like adding glFlush at some places to see if it fixes it. (this should not have performance implication).

Thanks a lot for the investigation! I guess ideally we could find a simpler fix, but if that's difficult this seems reasonable.
