Between MWO and Crysis 3? Yes, they both use CE3. There's no evidence of significant multithreading beyond 4 threads in MWO, however. I can't speak to Crysis 3, because I haven't' looked at the benchmarks, but this is how MWO behaves:
The 8150, despite its enormous processing power, isn't faster than even
Nehalem i5s and i7s. You'll also note that the 6 core i73930k is slower than the four core and four thread i5 2500k, again showing no significant use of more than 4 cores.
Here's what's more important though: NONE of these CPUs manage 60 fps. Any GPU that's at the level of a GTX 660 or 7870 can manage 60fps at max settings in the game, but
no stock CPU can.
Here's what the GPU distribution looks like:
Again, note that even a modern midrange GPU can manage 60fps average on "Very High" at 1080P, but look at the CPU they had to use to even
test their GPUs!
They had to overclock a 3930k to
4.8ghz just to be able to get fast enough framerates, CPU-side, to be able to even test higher end GPUs, because that's what it takes to not be always bogged down below 60fps. Had they instead used a stock 3930k, or even a higher clocked 2600k, all GPUs from the 660 on upward would have shown the same framerate.
So the game can be GPU-limited, in the sense that there are GPUs that can't run the game at 60fps, but it's far more CPU-bound, at least compared to most games, in the sense that
no CPU can run it at 60, and midrange CPUs have a hard time managing more than the 40s, and those are averages. Minimums are 20s for midrange CPUs, and 30 or 40s for high end CPUs! I've observed in look at this issue myself that those minimums are basically just what you constantly hit anytime one has a lot of mechs moving around them. As compared to most games, MWO bottlenecks on CPUs much faster vs GPUs, so a computer that might be GPU-bound in, say, Crysis or Metro 2033 might well instead by CPU-bound in MWO. Because gaming systems generally pair CPUs and GPUs of roughly equivalent quality -one is not genreally going to get a super high end CPU and mediocre GPU, or do the reverse- most gaming systems, regardless of age, are CPU-bottlenecked at present.
This is standard behavior for CE3 in DX9. Crysis 2 behaves the same way in DX9:
but CE3 loses all CPU-dependence in DX11:

Note that in that link, an Athlon II X4 is only a few fps off an i7 2600k at 1080P
Edit: Note in the second chart, at 4.8ghz, that 3930k is STILL bottlenecking those setups! Notice the 62fps minimum is the same across all higher-end GPUs.
