Stopping PIE lags when Project/Editor Settings window is open.
This issue occurs on 4.14.2 and 4.14.3
Windows 7 64 (Enterprise - latest updates)
1) Create and launch a new Third Person template (likely any type of template/project is OK).
2) After the project loads up, go to "Edit" ( top left of the main Map window) and click on "Project Settings".
3) Click "Play" to PIE once the Project Settings window becomes visible. (Leave the Project Settings window open.)
4) Once PIE becomes functional, click "Stop" to stop PIE.
Result: It takes approx. 5 minutes for the user to regain control of UE4.
Close the "Project Settings" or "Editor Preferences" windows before PIE.
Your dxdiag shows you should have plenty of ram and video ram + processor speed to run UE4 without lagging regardless of floating windows. However, in order to address a bug, we have to be able to reproduce it on our which we have not been able to do in this case.
That said, the UE4.15 Preview is scheduled to launch today if you want to see if the issue persists in that version. Also, if you haven't already, you could try installing UE4.13 to see if the lagging occurred in previous versions of the engine. If you choose to do either, please let us know the results.
