Game Stuttering & Stuck at 3 FPS

Game is unplayable due to buffering and being stuck at 2-3 fps. 

I will startup the game normally from either steam library or desktop shortcut and be prompted with a blackscreen for a few seconds and then a stuttering video of the PS logo video and stuttery audio as well. Waiting it out yields no results as well. I will be sent to the setup screen where I will can adjust screen brightness but still have stuttering. I have tried reinstalling graphics card drivers, going back to the older GPU driver, a restart of the pc, making sure all updates have been done on pc, getting rid of any overlays, changing refresh rate of monitor, and a clean reinstall of the game. Nothing works. The game is still stuck stuttering at 3 fps and is unplayable due to the subsequent lag. 

Please help.
