@PREDALIEN No, this is while running the packaged game, and this is a capture of a virtually empty scene (it’s just a camera looking at a plane) well after it has been launched.
Just did a test of the project with -corelimit=1 as a launch parameter. Our product processes a bunch of 3d data in parallel and displays it to the user (think gigabytes of data). I observed in profiling that limiting the cores to 1 makes it FASTER to run our processing, and I assume it’s because the CPU is no longer tied up doing who knows what.
Really need to figure out what is going on with this CPU usage.
