Diablo 2 Lord of Destruction CPU Reducer

Iam in need of a program that reduces the cpu usage by the game diablo 2 made by blizzard. 2 Things can be done: 1. Modifiy the program i already have that reduces cpu usage (reduce it even more) 2. Create a new program that will reduce cpu a lot more than my current program Current iam able to run 30 d2s with the private program that i have with lag most of the time I need to be able to run 75+ d2s effectively without any lag. *Do not bid on this project if you are not going to respond fast*
