I made a quick test with CPU at default clock speed (2.9GHz and Turbo enabled) and OC:ed to 4.1GHz.
nVIDIA settings: AF = 16, AA = 8.
Ship: Orient Star
Location: New York, heading towards Manhattan with Statue of Liberty on port side.
All graphics settings maxed out. Two cloud layers.
I measured fps with FRAPS and got this result in Orbit camera mode:
- 2.9GHz = 19 fps
- 4.1GHz = 20 fps
This is odd
The sim feels smooth and responsive at either clock speed. I changed the grahics settings to Medium and gained 3fps.
But as long as the sim is smooth I don't bother with the fps. I only want the mission to work OK.
