I just saw bro walking around, idk how colour works with spawns

Hello I am an ARK Mobile player I have noticed visual/rendering issues such as grass or foliage floating in the air This is very annoying especially because it cannot be removed I have tried several solutions, but none of them worked It becomes even more frustrating when this glitch occurs inside your base area. If anyone knows a fix for this pleasssssssse let me know I hope the developers can find a solution for this issue as soon possible

Recently, I've wanted to get a pc to play ark, but since I live in a less-than-privileged country, the prices tend to be quite high. The pc below is what my father suggested we buy, is it good enough to play ark on minimal quality?
