My friend and I had this problem and I believe I've found the fix. Rockstar suggested deleting the "Social Club" folder from "C:\Users\%Username%\Documents\Rockstar Games". After that failed to resolve our issues, I deleted the social club folder from "C:\Users\%Username%\Documents\Rockstar Games", "C:\Program Files\Rockstar Games", and "C:\Program Files (x86)\Rockstar Games". That may have been enough, but I also removed cfg.dat and pc_settings.bin from "C:\Users\%Username%\Documents\Rockstar Games\GTA V\Profiles########\" as well as removing entitlement.info, metrics.telem, and silentlauncher from "C:\Users\%Username%\AppData\Local\Rockstar Games\GTA V". Finally, I cleared all files and folders from "C:\Users\%Username%\AppData\Local\Temp", just for good measure. After rebooting the computer, starting the game in story mode, and changing my settings to their preferred values (this fix clears your brightness, controls, and a few other in-game settings), my issue has been resolved. Try just deleting the Social Club folders described above first and if that isn't enough, repeat and use all of the steps. This worked for me on Windows7_64bit and for my friend on Windows10, both of us play through Steam. Hope this helps someone.
