I've tested a large number of graphics cards recently with STO and one thing I find rather amazing is the extremely high load STO places on the GPUs. In most ground missions and some space missions, it's easy to find very high end graphics cards reaching loads of 92-100% GPU usage continuously. This 92-100% GPU usage is seen even on high end Crossfire and SLI configurations.
Another concern is I doubt it's the lighting, since for AMD configurations, I had to disable Dynamic Lighting or many of the setups will crash. Despite disabling Dynamic Lighting, the load is still consistently high.
This would be a cause of a lot of the overheating problems which many users have been complaining.
My question is, what is in STO that requires such a consistently high load on the GPU?
