Guild Wars 2

So this game is completely going nuts on me. Everywhere I go, everywhere I walk, turn, and look, goes absolutely ballistic on me with graphical glitches!
Things that shouldn’t be there, phasing in and out of existence! Objects of scenery literally flashing before my eyes only to disappear with just a flick of a camera angle change or when I take another step forward.
The attached pictures are a small but accurate summary of what I’m going through, and on that note I particularly like the npc Charr with a bush growing inside of him (which even though the picture doesn’t show it, was flashing between green and red).
I’ve tried re-installing the game but that hasn’t changed anything. And while ultimately I find this more funny than annoying, I would still like a fix on this as soon as possible.

The second one looks like artifacting.

Off the wiki for “Digital artifact”

Hardware malfunction: In computer graphics, visual artifacts may be generated whenever a hardware component such as the processor, memory chip, cabling) malfunctions, etc. causing data corruption. Malfunction may be caused by physical damage, overheating, insufficient voltage (sometimes due to GPU overclocking), etc. Common types of hardware artifacts are texture corruption and T-vertices in 3D graphics, and pixelization in MPEG compressed video.

I’ve had this happen many times with past computers and its usually due to overheating.
