Re: St st st stutter
Steam version here but sadly the same issue.
This is an Unreal Engine 4 game that has been released without a pre-shader compilation stage as the game first loads or during the menu so the shaders are being generated as you play and because Unreal Engine 4 is not very well optimised for multi-threaded CPUs you get a stutter the first time a new effect is generated. Eventually all the shaders will be generated but the cache will reset once you update your graphics driver and/or if the game has a big update.
It just beggar's belief that EA released the game like this after their own Star Wars Jedi: Survivor, also a UE4 game, was released with the EXACT same issue!!! Even now Jedi: Survivor is a travesty of a PC release as the developers never bothered to fix it properly so performance, especially with ray-tracing, remains poor and it has both shader *and* traversal stutters. Lovely!!!
I expected better from an experienced and talented developer like Codemasters. I am very disappointed and will be requesting a refund from Steam where I bought the game.
