How many ghz needed?

[Flyby]

Just a question about ghz: how many ghz is (generally) helpful for CoD? IIRC the recommended ghz in the system specs is something like 2.66(?). I see some guys running well over 4ghz (quads mostly), and wonder what the return is in terms of FPS gains, or smooth gameplay. I've got this old i7-920 (DO stepping) laying about and am wondering how much juice it will need to run CoD smoothly. As am aside, as a frequent visitor to [Hard] OCP, I see that site setting it's 920 to 3.6ghz " to remove the CPU bottleneck" when testing GPUs. I always figure our combat flight sims probably strain the CPU and GPU a bit more than the average pc games that site tests. Just my opinion.

I have an I7-920 @ 2.66ghz and with HT off so it only shows the physical 4 CPU cores, the game hardly taxes the first core above 50% (12.5% total) and the other cores register very little use so far and that’s with a GF GTX275

I'm running an I7 920 @ 4GHz and booting into stock speed of 2.66GHz shows the extra speed when over-clocked definitely helps (as you would expect) as b101UK mentions though, just now all four cores are not getting a proper workout, this is due to change with further patches though.

Thanks b101. So at 2.66 ghz your cpu's first core is hardly taxed by CoD even as the other cores show little use?
Katana, your cpu @4ghz helps over the stock clock how?. I'm not understanding what you mean in light of b101's claim that at stock speed his 920 is hardly taxed.
I'm a bit confused.
thanks,

1.21 jigawatts !!!! Be sure.

Cant believe no one has said that yet.

I meant most flights sims/games in general, FSX in particular sees a big performance gain once the CPU is over-clocked.

Once IL2 is properly optimised for CPU and multi-core we should see those same sort of gains too in this sim.

EDIT: and come to think of it, IL2 CoD maxs out core one on my quad at stock speed and over-clocked ... I use a G19 keyboard with the performance meter on its LCD and can monitor core usage in real time while flying the sim.

I can only speak for myself, too many variables with different PC hardware, one obvious difference between my rig and b101's is that I'm using a GTX570.

Thanks for the clarification, Katana. I agree, there are too many variables between systems. I also agree that older sims benefit from an overclocked cpu. I think CFS3 falls into that category, as it was a cpu-hog too.

I also agree that hopefully, IL2_CoD will benefit from multi-core optimizing. In fact Luthier seems to be indicating that the results should be pretty good once optimizing is done. We'll see. Certainly we all hope that's true.
