I made a simple project with UE4 (version 4.20.3), to check if it's possible to capture a frame using DX12 with the last version of GPA (18.3).
The capture worked (ctrl-shift-C) and I see a file saved with the .gpa_frame extension in the Docs/GPA folder.
But if I try to open it with the Frame Analyzer I get this error:
"An internal error occured. Graphics Frame Analyzer may fail to work correctly. Reopen the frame to fix the issue.".
I tried more times to reopen the frame, but without success.
Is there anything I can do? I'm using a PC with a GeForce 1080 ti and the latest nvidia drivers (416.34).
Could you send me a private message with the frame attached to share with our engineering team? It'll help us identify the underlying issue.
Also, could you send the about info found under button in Graphics Monitor?
