Yes, i still havent solve the problem because i couldnt find the cause( besides my very limited time due to personal life and lack of information in this case ). If it was script problem, it should have happened in rel004 too because neither Mashreq nor me added anything in client-side script during the upgrade to rel006. Actually, many things were removed from client-side script so it should be lighter. Most of the update were in server-side and it's the server that need to do the works, not your PC so your FPS should not be affected.
The FPS problem could be caused by your PC, other program/drivers, your game/vcmp/EC server( but i still dont think it's script fault because VCMP dev gave pretty much limited access to client PC besides the scripts works the same for everyone so if it happened to you..it should also happen to other players...Well, unless we are using a function/vcmp feature that was not optimized nicely or has unexpected behavior..which we still dont know what it is ). It's pretty hard to find the cause because of my limited time, lack of information and i cant test it either as it never happen to me.
