I was wondering about this passage in the Q&A:
Q: Does DCS: A-10C use all cores on my CPU?
A: Not fully. It does include the new sound engine which operates in a separate thread, and does take advantage of some DirectX threading features when running on Windows Vista or 7.
Right now I have my i7 860 overclocked using the Turbo-feature which means it is more optimised for single core apps. Does A10 benefit more from a high single clock or does it use more cores? If it would I would disable the Turbo and shoot for a higher clockrate for all cores.
