@William Sitton (william) : Can you reproduce the performance issue with the files I uploaded ? Have you a file I can test ? I am here if you need.
Having to replace the BSDF shader with standard shaders or having to delete objects to recover from performance issues is a pain (even if I can live with it...) This a lot of trials and errors.
I hope somebody will confirm someday and that a fix will be found...

Found a workaround !!!!
Replace Principled BSDF with a glossy or diffuse shader for the materials that have an impact on the performance. Everything runs smoothly.
I will continue to look for the parameter in the principled BSDF that makes the interface slow. Perhaps I will find something.

Tested with another scene "SimpleBoolersBot" which is extremely laggy too:
2 possibilities to recover from the extremely slow performance
Tested with RC1 and this the same problem. Is my config not capable of handling such a little scene in 2.8 ?

Unhide object wheel.001 = performance issue
With the scene "CarGPSimpleBug2"
When I use the "Pneu" material or "Material.004" on Plane.014 viewport becomes laggy every time.

Open the blend file I uploaded. Select the object "Wheel". Add a new material = Slow performance.
Put the material named "Carrosseie" for example on it and there is no performance issue.

Thank you for the bug fix too ! As Isaac Freeman said, it seems that the texture projection from an object doesn't refresh in lookdev. I have to go to cycles render to see it. I would like to know if it's an Eevee limitation too.

Same bug here : T63524
It seems to be the same bug in "T63826: Crashing file."
I have the same crash when i switch to shading with the blend file.

The "crash report" file is from osx if it can help
Same crash with today's 2.8 beta build on High Sierra Macpro and macbook pro.
Tell me if I have to report this crash every 2.8 daily build or if I should stay quiet and not bother you with that.

It crashes in lookdev preview mode and Eevee renderer mode. No problem with wireframe, solid or cycles preview modes. So I agree it is eevee related.
Same crash with today's 2.8 beta build.

Yes Ctrl+T is node wrangler. Deactivating it won't solve the problem.
I always download the most recent build. (Every morning ;)
I am reproducing the crash with blender 2.8 beta build of April the 16th.
I updated Cuda from 410.130 to 418.105 and I have the same issue. Could this be Nvidia related ?
I (and many 3d artists) won't update to Mojave because of Nvidia compatibility issues ...?
I hope it can be solved or at least reproduced by someone.
I also unchecked Cuda in Blender preferences but it doesn't change anything
I tested on windows and there is no crash ! I can only reproduce this on OSX High sierra 10.13.6.

I can reproduce this on every Mac OSX High sierra Blender 2.8 (Mac pros and MacBooks) with factory settings. Haven't tried on Linux or Windows.
