Graphics question

[Grimight]

Okay so I'm new to this game, I'm thinking of even paying to play dragon. I've been looking for a game with playable dragons forever! Everything runs smoothly and there minor if any lag so far, however, the ground keeps glitching, graphics see to disappear and show terrain for a different area. It happens in small patches so it's not like the entire floor glitches. But I'll be in dirt somewhere and suddenly there's rock or grass in a small patch and it's usually when I'm running. Has anyone had this issue? Or does anyone know the fix?

sounds like a cache issue.
open your Istaria folder, and then your world_cache folder, and delete the folder(s) that read either of these

orderhorizons
Chaoshorizons
Blighthorizons

that should fix the issue. otherwize check you RAM and/or graphics card. if the drivers are out of date that may be causing glitches as well
