Mine was 45 something, I think 45.25, I need to upgrade though, it was chugging on the high detail galaxy collision.
It won't the load thousands of moons simulation, tons of moons(400) it runs at about 13-14 fps.
Also note that using the cpu or cpu tree is a lot slower than using CL(which run rather smoothly).
The impact marks don't disappear/cool over simulated time.
Using anything larger than 500m with basically create armageddon, with all the debris which in turn make's more explosions.
All in all, stability and optimizations and increased performance which requires less resources should improve fps during heavier simulation load.
I'm just beginning to use that omnipotence thoe.
EDIT: Second test is 49.12, I reduced the screen size(windowed mode)
