No.
Most of the 317 clients you people use are monstrosity's with everything hard coded. You cannot improperly add all sorts of new features and expect the cpu usage to be the same. The only real feasible solution is to start from a fresh 317 client and add everything properly. There's no need to hard code sprites, models, or any data what so ever. You would also want to go ahead and fix how all this new crap is processed and drawn onto the client. That's what's causing your cpu usage to be high.
