The lawn in Jinan's Yaoqiang area has a granular texture.

I've adjusted every setting in the video quality menu, but it only helps a little—it doesn't solve the problem completely.

After comparing it to other time periods, it seems to be most noticeable between 8:00 and 8:30.

The graphics card is an NVIDIA, and the drivers were just updated, so it shouldn’t be a hardware issue. I’ve also verified the game’s integrity.
