At first I thought it was my video card driver but I've installed the newest version and when that didn't work I found the "recommended" driver the site suggested and that still didn't work. I've gone into settings to change AA to every setting including off. I've changed resolution, shadows, and pretty much anything I was comfortable changing without a fix. If you can't tell by the pictures, it almost seems like textures aren't loading right. When I'm on the ground I have a circle around me of tiles that look correct but everything else is a purplish color with small square artifacts in the sky, possibly stars, maybe. The circle follows me, so wherever I go the circle that surrounds me looks right but everything else isn't. Trees look right, water looks right, just not the ground. Has anyone else experienced this? Also, I'm running on the demo and was wanting to purchase the alpha but not if I can't get this fixed. Any help is appreciated.
