Hello, and Graphics Glitch

[Bakkels]

Ah now I see your problem, I just thought you weren't happy with the overall graphics quality.
But yeah these reflections are just plain weird. I have never seen bugs like this before, and I doubt it has anything to do with your computer's performance. I'm no expert but it might help to update your graphics drivers. And downloading the latest directx never hurts.
By the way, I wouldn't call it a small glitch, these reflections would really annoy me after a while. I hope you'll sort them out!
