Lag with 5000+ troops?

Same here, do you use Windows 7?

Yep.

Oh the irony: your i7 is hardly used but it is precisely your i7 that is the bottleneck. You see, RTW is hardly multi-threaded; and during the battle both the engine and the logic (AI) must share a thread. Since the load on the system increases as the variables in the scenario (i.e. objects, and complexity of the physics of those objects) do you will quickly max out one core and simply run an underpowered single processor system as far as RTW is concerned from then on. Hence only 25% CPU load, but a lagging game nonetheless.

You may be able to run RTW/EB a bit smoother if you look into setting both CPU affinity of the cleanup and the RTW main processes/threads via the task manager (Processes tab).

But the thing is, in my task manager, I see the 2 cores being used at less than 50%, so even if RTW only uses 2 cores, it's not using my cores to its potential. Furthermore, an i7 is faster clock-per-clock than Core2s due to better architecture, and it has turbo boost that increases the speed from 2.66GHz to 2.GHz when 2 threads are being used and to 2.9GHz when 1 thread is being used.

In either case, I see my CPU usage for the cores actually being used at less than 50%
