L.A. Noire - Game not launching & Unlocking 30FPS Cap

Ok, so you just bought this L.A. Noire and it totally won't launch, just try the fix below, it should work for you.

How to fix it

1. Navigate to ..\common\L.A.Noire (or wherever you install games, you can go to the properties menu of the game in the library and just hit "Browse Local Files")
2. Change compatibility settings for LANLauncher.exe and LANoire.exe to Windows 7, Run as Administrator, *AND* Disable Fullscreen Optimizations
3. Create a shortcut to LANLauncher on the desktop, or add it as a non-steam game.
4. Launch the game from LANLauncher
5. When the launcher opens, go to options and add "-npd -str -nonv" (without quotes) to the "Command Line" box. Also change the renderer to DX11 if your computer is compatible (I would hope in 2019)
6.  Hit OK and hit Launch Game

The game should start like normal now. Steam will recognize it as LA Noire and achievements will be tracked. I don't know why this has to be done this way, I think Steam is trying to open LANoire.exe and not the launcher.

FPS Lock Fix

I also recommend using Widescreen Fixer to change the FPS cap (30FPS) to 60FPS. There is little reason to play this game at 30, the facial animations do look a little strange at 60 but they are not broken.
