CoH Multithread-capable?

It does; run Process Explorer and check your CPU usage and you'll see that cityofheroes.exe does something in each CPU:
Maybe you're bottlenecked by the GPU. You can throw a lot of CPU at the game, but if the GPU isn't up for it, you won't get a performance boost.

Thanks to @EnsonsDeath for the GVE code that made me VIP again!
Sweet, thanks. All I have to go by is Task Manager showing me that both cores are in use. But, I'm usually running 3-4 other programs in addition to CoH, I don't know how much use CoH is getting out of the second core. It's not so much performance issues, I just want more. >.>
CoH doesn't seem like a terribly CPU demanding game, to be honest... But MY, does it use the memory. I just recently upgraded the GPU, so that's not an issue. lol

CoH's performance profile largely depends on what you are doing and what graphics options you have enabled.
With the OpenGL 1.4 Shader path and low particle options CoH isn't exactly all that CPU heavy. You can still get away with a playable 10fps or there abouts on 1ghz AthlonXp's
With Ultra-Mode graphics options enabled that performance profile can change dramatically. The shadow maps and particle effects can chew up processing power pretty quickly.
I though CoH only uses up to 2 threads *at one time*.
As processes come and go, they'll wind up being distributed over all the threads as other background processes grab a thread and tell CoH to move on to the next one.

While the game has something like 6-9 threads, only two are chewing up the bulk of CPU time and can run reasonably in parallel. The other threads either run very quickly and or infrequently to matter much.

Title says it all, more or less... Does CoH take advantage of multiple processing cores? More specifically, will I notice a significant performance boost upgrading from a 2.66GHz Dual-Core to a 3.2GHz Quad-Core? If the devs could confirm, that would be nice, but I won't hold my breath. I can't find anything by searching, other than using a command line flag (-renderthread 1, I think it was?) does something to help in multithreading, but that was from '07, so I'm not sure if anything has changed.
