Question Huge graphics Glitches/Visual Artefacts with RTX4070

[DoubleDu]

Hi ! It's the first time I experience such horrible graphic glitches, it's not a very first, but usually it disappears when I update the drivers or restart the game.

I just finished a 50+hours stretch on Kingdom Come Delivrance 2 and it happened to me once or twice in very small amount and a restart of the game fixed it.
But in Avowed I can't get rid of it.. I updated my drivers, tried all the different options for RT and DLSS... It's always here when I load my save. Here's how it looks :

With RT ON :

With RT OFF :

Thanks to those nice enough to help me make sense of it.. Here's my setup :

OS : Win11
MB : ASUS ROG Strix Z790-F Gaming WiFi II
PSU : Corsair RM1000e
CPU : i9-14900K
GPU : Gigabyte RTX 4070
RAM : VENGEANCE DDR5 64Go, 5200MHz
