Note that with your resolution you may not receive the same results using AA, AF, QCSAA, CSAA, MSAA etc. Start with just AA at 4x for you screen size. That should cause a noticeable change in your game, if not.. it's not working. From there, you would then try forcing AA using the Control Panel. Add ME3 by clicking on the Manage 3D settings, clicking the Program Settings tab, click the Add button, and navigate to you install directory (ie. * Mass Effect 3BinariesWin32MassEffect3.exe).
From there enable Antialiasing - Gamma Correction, and set Antialiasing - Transparency to 4x.

maxzoomaimerror = (X= , Y= )
minzoomxaimeror = (X= , Y= )

X and Y fields should be the same. Bigger values mean less accurate. The above two values fix accuracy when not holding down right mouse, or aiming. “zoomaimerror” is for accuracy while aiming.

Mass Effect 3 Weapon Tweaks

damage = (X= , Y= )

X is value of weapon damage at level I, while Y is the damage value at level X.

Note: Make sure you also fix the statbardamage attribute to be the same values as the damage that you set. There are two other values for stat bars: accuracy and rate of fire. These two values don’t correspond with the values that actually affect the behavior of the gun.

Rate of fire

rateoffire = (X= , Y= )

Both X and Y values should be the same.


encumbranceweight = (X= , Y= )

Value x is the weight of the weapon at level I, and value Y is the weight at level X. For example, a weight of 1.4 means your cooldown will be slowed by -140% if you equip this weapon.
