Below 60 FPS On Low (GTX 770)
FX-6100 processor. Not that the CPU is poor, just poor with this game which uses Dx9 and few processor intensive threads. Since you don’t say what FPS you are getting or where you are getting it’s tough to say you are somewhere that binds up the CPU, thus slowing the rendering loop.
I also suspect that if you up your settings in game you won’t notice a significant decrease in performance which says it’s not GPU but CPU limited.
RIP City of Heroes
I get around 40 FPS on High settings, 30 on Minimum settings.
So Vsync off and Limiter set to unlimited?
Again where and doing what? It does make a huge difference in the game.

A current AMD FX cpu is the wrong tool for older DX9 games, which includes many mmos. Modern titles with dx11 or mantle work well on fx series.
So for now, set animations to low, reflections off, shadows off, character model limit lowest, character model quality low, everything else you can set to the highest possible. Also if you don’t like in game sound using the -nosound command will disable all ingame sound for a bit more performance.
