High Priority on Unreal Engine 4/etc. Games

[Emerstta]

Yes, as the title says, I'm trying to make Tower Unite run with high FPS and play better. I entered the launch options. Lower my performance, environment, and media to low or off. And set both Tower.exe and Tower-Win64-Shipping.exe to high priority.

But every time I set both Tower.exe and Tower-Win64-Shipping.exe to high priority, it resets back to normal every time I exit Tower Unite.

I'm looking to find a command-line from the Unreal 4 engine to keep the game as high priority and won't reset back to normal again.

I found a couple of guide about making Tower Unite run faster with high FPS to be outdated, and I never find a solution to this problem.
