Help! This graphics makes no sense to me

Hi guys,

So played witcher 3 on my ps5 but never managed to finish it, so I decided ill start again from the very beginning

So about to start witcher 1 on my pc and that works and looks fine (outdated graphics aside) and thought i better check i can run witcher 2 before I get carried away

The game runs fine but for some reason the texture is off and I'm not sure why? My PC knowledge isn't great and rarley use it but it's the only way for me to play the trilogy so if anyone can help you'll have my forever gratitude!

Thanks in advance!
