I have two GPUs in my PC but Twinmotion alway uses a GPU that is not connected to a monitor.
Suggested solution in knowledgebase does not work. I also tried -graphicsadapter=0 in launcher settings and in shortcut settings.
Assigning gpu in windows settings also does not work. It’s always been a problem with Unreal engine. I have never had such issues with any other apps, but only with UE and Twinmotion.
