Huge thanks to dangerousbob88 for this: I found a solution in this older post…
I’m honestly not one hundred percent sure if this is a true solution or just a hack, but it did solve the problem. After reducing the screen resolution 70 percent via console command in my Game Mode, the packaged game now runs at up to 148 fps. That’s one heck of an improvement… but again, not sure if that’s a solution or a hack?
