I've been hacking through several formulas across this site and others. I'm running into problems trying to figure out the true DPS when the character is dual wielding. Let's take a low level Barbarian for example.

Strength: 28
Damage Increased by Skills: 0%
Attacks per second: 1.24
Crit Chance: 5%
Crit Hit Damage: 50%

Weapon Stats:
1 Hand Spear: 7-11 Damage
Spear Base Attacks per Second: 1.20
Bonus: Increase Attack Speed by 3%

So, the formula for this would be (or any one handed character):

7 + 11 = **18**; (weapon damage range added together)
1.20 * (1 + (3 * 0.01)) = **1.236**; (base weapon speed, times any IAS bonus on the weapon plus 1)
(0 * 0.01) + 1 = **1**; (damage bonus from skills. this character has 0)
((5 * 0.01) * (50 * 0.01)) + 1 = **1.025**; (crit chance * crit damage)
(28 * 0.01) + 1 = **1.28**; (attribute to percent + 1)

multiple all of the results above, and divide by two and you get: 14.59

which is the correct DPS of the character. But now, how would you calculate the DPS of an offhand weapon equipped to this character, say:

1H Axe
Base Speed: 1.30
Damage Range: 9-14

Does anyone know how to calculate this?

The actual formula the game calculates damage is:

(AvgMainHandHit + AvgOffHandHit) / (MainHandSwingTime + OffHandSwingTime)

which equals:

( Average Double Hit Damage ) / ( Average Double Hit Time ).

I purposefully named it Hands, because we calculate both weapon and character statistics into it.

The formula for damage is:

(1 + passive skill boosts)(Average Weapon Damage + ((minimum damage bonus + maximum damage bonus)/2))(Weapon Damage Multipliers)(Attack Speed)(1 + ( crit% * crit damage %))*( 1 + (main stat / 100))

For Dual Wielding:

((1 + passive skill boosts)(Weapon 1 average damage + ((minimum damage bonus + maximum damage bonus)/2))(Weapon Damage Multipliers)(Attack Spee)(1 + ( crit% * crit damage %))( 1 + (main stat / 100))(average attack speed of both weapons / weapon 1 attack speed) + (1 + passive skill boosts)(Weapon 2 average damage + ((minimum damage bonus + maximum damage bonus)/2))(Weapon Damage Multipliers)(Attack Speed)(1 + ( crit% * crit damage %))( 1 + (main stat / 100))(average attack speed of both weapons / weapon 2 attack speed)) * 0.575
