In terms of the Graphics or TTK, I think the game is just fine.
If you guys need proof for TTK/Hitreg, just try playing the "Local Play" mode with any gun you like except the sniper guns.
Also my game runs at 45fps minimum on rx460 with the tweaks give below with these settings on my full HD Dell P2414H overclocked at 75Hz.
Before applying below edit launch the game and put everything in game settings > video to off/low and 16x for Anisotropic Filtering and Apply changes and load any map in local to confirm the graphics settings and then Quit the game. Also do not change any thing from settings menu after the game is launched while using edit or it will get reset by game.
Copy this code in your GameUserSettings.ini
Also report back if you try this out.
I tested this settings without changing any settings from in-game settings.
After you launch the with this edit, don't change anything from the in-game video settings.
