Well, both have their pros and cons. Affecting every variable will take a hell lot of time to implement, especially considering the amount of code you have in SoulHunter (You are over 10'000, right?). But affecting variables is more stable than affecting the synchronization.
I wrote a little function that affects the syncs. The upside is, that it is very easy to implement, because you just have to replace every sync command with the function, the downside is, that it takes up to 3 seconds to stabilize. Anyway, let's just see how you go.
Here's the function:
cometSYNC()
This function will affect the synchronization so your main loop will run at a constant speed of a given value. You can use this function instead of using "sync", but never use both! The sync rate must be specified using an integer value, the update value must be specified using an integer value, and the return value is specified using an integer value.
cometSYNC() will count the loops actually performed, and subtract the result from the loops it should have done. From that it calculates which synchronizations should be evenly skipped the next loop.
Pros
-Very easy to implement
-variable function
Cons
-Too unstable for Net Games
SYNTAX
return value=cometSYNC(sync rate,update)
how to use
the return value returns the FPS rate. The sync rate is the rate you want your loop to run at. The update value specifies after how long the function should update the counter. The more objects you have in your game, the higher this value should be. I found a value of 500 runs well.

Enjoy!
I think I'll go over to the code snippet board and post this there...
