Sims 4 running terribly even with above and beyond specs

As the title says I recently bought the Sims 4 base game, no expansions and attempted to run it. The game runs terribly, the computer itself does not appear stressed in any way with no aspect of it running above 60/70% however the entire game is juddery and slow, its as though its running at something insane like 10-15 FPS.

I have done all your standard checks, no CC no expansions, repaired game through origin and even fully re-installed it. CCleaner has been run and yet nothing seems to work. 

Computer Specs:
Windows 10 - 64 Bit

AMD Ryzen 5 1500X Quad-Core Processor

8GB of DDR4 Ram
A Nividia GTX 1070 Ti Graphics card.

Its just very odd. I can run the witcher on max graphics but this game is terrible. If you know a fix please let me know, the game is a lot of money and I dont want to waste it.
