Does having a modchip (vs swap magic dvd) improve PS2 laser performance?

Right now I have a brand new V9 PS2.

To make a long story short:

1) I'm using Swap Magic v2.0 DVD to boot my DVD-R/DVD+R games. Most of games are VERY choppy. I've tried LOTS of media (Ritek G04 DVD-R, TDK DVD+R, etc etc).

2) If I was to get a modchip (DMS3 or something), would that IMPROVE laser performance? Would my DVD-R/DVD+r games suddenly stop skipping?

The only benefit of having a modchip (that I'm aware of) is that you can *more easily* boot games. Once the games are booted and playing, the only factor in performance if the laser, right?

...or does the modchip matter as well?

It might! But what do originals do? Are they choppy?
Did you try to load an original through the swap disk? (This will allow you to see if it?s the swap or the laser). If the original works with out the swap disk, but doesn't work with the swap disk then it might be the install/disk.
I don't know much about swap chips (I don't sell them), but where is it skipping (loading, playing, always), It may be one of the wires in your swap disk install (there's 8 right?)

Your correct though, in most cases after the game is loaded successfully; it should be worry free.
What version do you have? Version 4's are picky about mod chips (for me anyways). And I find that even though the mod chips are "compatible with all versions", there are some that work better than others.
If you did the install check it.
I can say for sure that after a mod install if the disk was skipping (meaning it booted) it has been the laser. But swap chips are supposed to emulate original disks! Right? If that's the case maybe your disk is incomplete/scratched, and its not finding a type of file/operation on load that it?s supposed to
