Poor Performance - FPS stutters

Hiya, I've seen some other threads on this but was told to ask for help here by EA's service help themselves so that the community management could see it?

I have a gaming laptop which I believe meets not just minimum but also recommended requirements -Eliminia ProProcessor -  Intel® CoreTM i7 14 Core Processor 13700H

RAM - 32GB PCS PRO SODIMM DDR4 3200MHz

Graphics Card - NVIDIA® GeForce® RTX 4070 (updated to the latest driver, which featured veilguard specifically)

2 x SSD drives, after my first attempts at playing I re-installed Veilguard on my second, completely empty drive.

I have all settings to the lowest they can get, triple buffering is disabled, I'm supposedly using around 4GB of VRam of a possible 8-ish.

Every few seconds there's a visual or audio stutter, the frequency of which makes combat incredibly frustrating and ruins any cutscenes. I'd like to run this game at better graphics than just performance based, but even at this it's not a smooth gameplay. 

The game is installed via Steam - I have already tried verifying game files. 

I have tried setting my NVIDIA graphics card settings to prioritise Veilguard as high performance, I have done a clean install to an empty SSD which has 1TB of space, I've updated the graphics card to the latest update, I've tried that anti-stutter mod, triple buffering is disabled, no other applications run in the background, my laptop is on charge and is only a year old, and yet even at the lowest possible settings I can't play this game properly.

Any thoughts?
