I’m using an MSI-GE72 laptop with a GTX970M. Proprietary drivers are compiled and working and UE4 works almost perfectly on it (Tried Ubuntu, but Arch is wayyy smoother) using primusrun. Very fluid, very fast.
When running a Standalone instance of my project to test remotely with another computer, although it works fine in PIE mode AND in selected viewport mode on the laptop, in “Standalone” preview mode, the new game title bar shows “GLSL430”, a red crosshair in the middle of the window and the tilde console (accessible, and I can type in it), and that’s it. Everything else is black.
I have seen posts with a similar issue mention the default map should be set in Project Settings.
Well, it is (although I doubt it has much value in my case, since I’m loading an external map on the server using open ).
Weird thing is, I have another older laptop and it works fine, EVEN with primusrun! The difference I can see is that when starting in standalone mode on that other system, I see GLSL150 instead of GLSL430. And, also on a desktop computer (with a GTX980), I see GLSL150 instead of GLSL430 in the title bar. I’ve also tried removing GLSL430 in the Linux tab in the project settings.
Now, when I ran UE4 the very first time, I had to change the Engine scalability settings to see anything in the viewport. Otherwise, everything was black in the editor. So, I’m thinking, is it possible the editor changed some parameters in viewport mode, but the standalone game mode ignores these changes? Can they be set manually (launch option, INI)?
