If you are thinking on the first scene you encounter when starting up the game (Rico laying in a sunbed with a towel with the square enix logo) it is not even a loading screen (it seems). A PC mod have made the scene skippable (makes the player log into the servers at the start at cut scene, rather than waiting 15 or so seconds, shortening the boot time by 2/3 of vanilla. Kinda stupid that this mod had to be developed. Like it should have been like this from the start.

Another thing that bugged me when i first played it was the fov (really small in vanilla), luckily a mod fixes this too.

the final thing however is maybe the worst.; the fucking handling of vehicles. man jesus. Its terrible. the turn-radius of the wheels of most land vehicles is not instant! Meaning the more you hold down the key the more the vehicle turns overtime, and then it TAKES TIME FOR THE WHEEL TO RETURN TO THE NEUTRAL POSITION making the vehicle continue the turn even after you have released the fucking key, making the handling incoherently clunky , unresponsive, and unpredictable. This is of course not true with every vehicle, but man.. that got me so riled up.. big difference when coming form gta5.

Or they got a really good bulk deal on treadmills and need to get rid of them all...
