[steam-3321460.log](https://github.com/user-attachments/files/30835144/steam-3321460.log) ## Symptoms <!-- What's the problem? --> The game launches but no meshes seens to be loading, only map textures like the terrain and trees. Characters models, buildings, rocks, static props, etc all invisible. The caracter can move and interact with the world just fine. The meshes themselves appear to be missing while terrain continues to render normally. Starting a new game does not change the behavior. The same hardware renders the game correctly under Windows 10. Issue only happens on Crimson desert, other games work just fine. <img width="1920" height="1080" alt="Image" src="https://github.com/user-attachments/assets/6c8be8d1-43bb-4b84-aa91-87c9f319f70b" /> Troubleshooting I already performed. 1.
