GroovyMame and strange arguments results (-syncrefresh -multithreading ... )

[befensor]

Hi people. In this cold evening I'm testing GM with FEEL Frontend and mame arguments as well. In my tests there are some issue, probably due to my poor experience with Mame but...

This is my arguments list:

-syncrefresh - aa -multithreading -waitvsync

Issue
-syncrefresh works, but I don't see any difference either if active or if not
-aa works, no differences
-multithreading don't works. When I launch rom, frontend remain in rom list (and I could launch again, but ever with no results)
-waitvsync don't works, like multithreading

Is correct or not? I put these arguments in commad line (via FEEL) but in mame.ini there is:
# CORE PERFORMANCE OPTIONS
#
autoframeskip             0
frameskip                 0
seconds_to_run            0
throttle                  1
syncrefresh               0
autosync                  1
sleep                     1
speed                     1.0
refreshspeed              0

Test on to E2140 @3200mhz, Radeon 4650, CRT Emudriver, Win Xp, FEEL, GM 0.179, Ghost 'n' Goblins

-multithreading was dropped from baseline long ago, so it won't work.
-syncrefresh/-waitvsync should be left as 0 if you're using -autosync (recommended, so GM activates them when necessary).
-aa... I don't know what it stands for.

Thank you so much Calamity, powerful explaination. Only one question: if a set both argument and mame.ini setting... what of these will "win"? Or they work together?

For examples:

if I set autosync 0 in mame.ini and launch mame.exe -autosync, will it be active or not?

Yes it will.
Command line arguments override mame.ini settings.

Thank you so much OZ. BTW, my tests on to arguments are done due to a little "tearing" and a minimum frame delay.

Do you think that update my GM 0.179 to 0.180 will improve this issue? Final Fight for example is in correct res and freq but a little tearing appear.
