Turn off computer or leave it on?

That could stress the components, and correct me if I'm wrong, every time you turn on the computer, it sends a huge electric surge, throughout the components.

current doesn't just surge. it is "drawn" by components. only motorised components like fans and hdds use more power while powering up. semiconductors (everything else: processor, memory etc) actually start to use more power after they've warmed up. that's just how semiconductors are.

copy that - shame not many game manufactors relise that yet thu:<

blame Microsoft for forcing the industry to use DX. OpenGL was the way to go in the good old days. it's not too surprising that OpenGL based games like Doom3 and Quake4 run better on Linux than Windows . i wonder if that has anything to do with why Microsoft disliked OpenGL.
