Okay.. We are starting to hit decent fps again. We are able to have dynamic shadows everywhere and still get a decent 40-60 fps on a mid range machine with 1280x720 resolution. (We still have some issues with the new cone light angles effects to shadow quality compare to point lights.)

But as for other note. There is still an issue we would like to tackle. That's when we are going for higher resolutions. If we do full hd resolution the fps is dropping back to around 20-30. I'm sure here we could use some further optimizations on the separate passes rendering.
* Sun Rays
* Underwater Effect
* Hdr (Tone Mapping)
* Bloom
* Motion Blur
* Depth of Field
* Ambient mode
and what ever else there are.

I noticed ofc that there are half resolutions for these but when the player changes to full hd we would like to have the possibility to adjust the resolution for our selves or atleast have a quater resolution passes.
This is possible on most of the other indie engines and should not be that big of a change since you already have the half res version ready.

Can understand if you are too busy but yeh..
We would really like to release the game as optimized as possible without getting any negative feedback on the performance..

Maybe I missunderstand, but if you are raising the resolution, shouldn't the frame rate drop?

It should yes
But developers tend to manage the drop by not actually raising all the passes resolutions.

any possibility to add quarter resolutions for some stuff?

I agree. Quarter resolution as an option would be a great step towards improving performance when needed.

most of the effects already runs on half/quarter
AO is only full/half, so I've listed it to roadmap as optional quarter
