Love playing in HD, really captures the atmosphere of the game. I used to use Standard Detail frequently on my older computer like 7 months ago which was a Pentium 4 with no GPU, but now that I've custom built my own gaming machine, I don't see why not. HD is awesome! Although full-screen is a little annoying, especially on Windows 7 :huh:

SD, fixed size.

 

Three reasons.

 

My pc is bad.

When you need presicion, the visible floor grid makes life much easier.

When you have fixed, you won't have to move the mouse as much, and not the eyes either, which is really a problem if the screen is large and you're up close. This means faster gameplay, skilling, efficiency, and less strain on both the eyes and the neck. SD game is SD.

HD resizable, works amazing and i can cruise other websites at the same time

I play in HD because I'm usually killing something, and I like to get the most out of what the game designers put in.

SD. My computer can't handle HD

HD Resizeable, max graphics. Looks beautiful, and the fact that it's hardware rendered means it runs smoother than SD for me.
