"-fps" argument only correctly limits fps on loading screen

[Jademalo.3724]

When setting the "-fps" command line argument, the value set is only used during loading screens.

For example, if I set "-fps 40" as my launch argument, the character select screen will run at ~110fps, the loading screen will run at 40fps, and ingame will run at ~45fps. I would expect all 3 of these to run at a limited 40fps, but clearly the only place the fps limiter is active is during the loading screen.

This seems like a fairly simple fix, and would be extremely useful for limiting to 40fps on the Steam Deck to take advantage of the 40hz mode.

As noted in the Wiki.  It's been like that for a long time.
