The second image is an RC-D
Ever since December last year I've been getting these graphical glitch's, I have the HD texture pack downloaded and both models and textures are set the highest they can.

I even have done Shader compiling each boot and that doesn't solve it either, and if it does it's very temporary. Is this even a shader issue?
Now I am running this on a SteamDeck but the game was functional before this for 2 years.

From what I know there hasn't been an update for a long time now. Both windows 10/11 have this issue, is this a result of texture streaming?
