Seen a few posts on here about the frame stuttering and minor lag but cant find any fixes that work for me.

First off like usual the pc can handle it, on paper its overpowered for days gone, but whilst playing through the game especially when on deacons bike, the frame stuttering was just annoying and very noticeable, I tried a few fixes like running the game in administrator and disabling full screen optimisation and all that but it just made it worse. Booted up the game after applying fixes and left lost lake through the main gate and got frame stuttering and two minor lag spikes (that didn't happen originally) before I'd even got to the end of the bridge.

I really love this game so far but the fixes aren't working and its really putting me off both days gone (because obviously the bikes an integral part of the game I cant just not use it) and also PlayStation games on steam as a whole as this is the first one I've bought and it seems very poorly optimised. Kinda makes me nervous to play others like horizon or god of war.

Any help with the issues?
