This is something odd I noticed today. I have the Unity bridge on my ship, and when I'm visiting the bridge, with no visitors, the GPU usage on my video card goes from around 75 percent (in spacedock) to over 95 percent - I was alerted to it by the fan on my video card speeding up.
It doesn't crash or anything, but I found it puzzling that it's putting a bigger load on the GPU when on the bridge than it does in combat against Borg ships.

Anyone else notice this? My system is as in my signature.

My card heats up rather fast just sitting on the login screen because its running at 170+ FPS, if it worries you you could enable the frame limiter at 60fps, most monitors can't refresh any faster than that anyway.
But I'll try that.
If I set the limter to 120 fps, it will go up to 85 fps (I keep vsync on); so it seems like the card is "loafing" when the limiter is set to 60. Weird.
