Graphical issue

Hi there. 

I am having problems with Dragon age: The Veilguard - it is getting to a point where I almost cannot play the game. My EA ID is Sigidus and I play the game on my PC through the steam app, I do not have the EA app. 

I am experiencing severe graphical issues where I am getting these massive texture planes slicing through the environment as I move the character and camera around. They are both horizontal and vertical and are especially bad in the lighthouse, but I have seen them all over the place. The character is able to run through them but they are completely opaque. 

I have tried restarting the game and computer, adjusting my graphics settings to anything from the lowest to the highest setting and changed from full screen to windowed mode. I have also tried making new characters however the problem persists and the "walls" seem to appear in the same places. 

My computer specs are: 
CPU: Intel(R) Core(TM) i5-8500 3.00 GHz
Installed RAM: 16.0 GB
GPU: MSI NVIDIA GeForce RTX 4060Ti 16GB
