PC lag and start-up crashes

I don't know how to video the controller issues, but its got to be an issue with recognizing the Dual Sense PS5 Controller instead of an Xbox because it occasionally shows the right glyphs then a menu change makes them xbox again. Turning off and turning the controller on again fixes the double input now. 

The speed up lag issue is minimal now, but its been replaced with random disconnects and just black screens with no menu access that force a client restart. 

I have picture of the oversized corner flags. 

I'll try and get video soon.
-Corner flags were only twice in World Tour 4 days ago, looked like a giant blue/silver cup trophy except oversized, bigger than the players in height and width.
-I've tried auto, low, medium, and custom medium resolution with everything else off. Mainly when players come on-screen (clearance) or shift between sprinting fast on attack/press, the game literally slows down, then some players move super fast and catch up. Connection monitor stays stable. Task Manager shows less then 50% cpu, less than 10GB ram, and less than 50% gpu pretty much all the time. This lag/stuttering is inconsistent. Only mode it doesn't occur in is Rush. 
-If steam doesn't see/recognize the controller before starting the game, the game sometimes picks the controller up. But I have to alt+tab or click the app on the taskbar EVERY time it loads, because the game doesn't command focus after the splash screen.  So it loads as keyboard first, then I have to press a button so it sees the controller. But as long as steam and the PS accessories app see the controller before the game loads, I don't seem to have a problem (cross fingers). It's when i turn on the controller during or after the game loads, the double input bug happens. 

Hey GhostxOnii​ do you have a video showing this?
