Bad frame rate on high-end hardware on Steam

I have an i9 9900k and RTX 2080 running the game at 1080p in the Steam version and I get constant frame drops (not just in the lobby) in a game whose original Japanese release ran flawlessly at max on laptops that were incredibly outdated even in 2012. Everyone says this is an issue with how Gameguard scans every player that loads into the map. Please fix this already, you haven't even commented on it in typical Microsoft fashion.

If you have V-sync turned on, turn it off.. It's the most common reason for FPS drops in most games.

Turning it off does nothing and I've never had issues with V-sync in my life before
