How would higher atmospheric pressure on an Earth-like planet affect rainfall?

Earth like planet has 3 atm pressure at it sea level. How would it affect its rainfall system?

1) Using internet calculator I got a result that boiling point for water would be 131°C, while freezing point would remain very close to 0°C. Would it affect evaporation rate under more normal conditions, like for example near 10°C?

2) The absolute humidity is only temperature dependent, thus no change here. (source: https://en.wikipedia.org/wiki/Relative_humidity#Misconception) Right?

3) Further condensation is theoretically not air pressure related but temperature related, so no direct change here, right? (source: http://www.ems.psu.edu/~fraser/Bad/BadClouds.html). However I'm not sure, how air pressure would affect condensation by being able to hold in air for longer cloud condensation nuclei?
