hey, I think I am missing some rain effects in the game. On the levels seat of power and power up there is the distinct sound of rain falling yet I can so no rain. Also the roads and objects all look wet which would also imply its raining.
I have watched a few videos of these level and about 60% of them show no rain where as the rest do, so it's either a really widespread problem or they removed the rain in the pc version and the vids I saw with it are on console but that makes no sense at all.

So once and for all is there rain in the pc version lol?
I run the game at max settings with a GTX 580 using 270.61 whql drivers

I played the game twice on PC and once on Xbox and I noticed the same thing. No rain in the PC...WTF?

When I set r_postmsaa=0, I have no rain on my single GPU system. But with postmsaa enabled, I do see the rain. However, I think that my other system with dual GPUs doesn't show environmental rain at all, it does show the water from fire sprinklers inside buildings though.

I'm not sure what's causing it, post msaa, Multi GPUs, or what ever else it could be, but I do have the same problem with missing rain at times.

The rain looks absolutely awful anyways, you're not missing anything
