I did comparison of v236 vs 0.241 performance with all effects enabled (except depth of field and skylighting) in Riverwood location (it have a lot of dip calls). Resolution 1920*1440, GeForce 650 Ti 2 Gb (128 bit memory bandwidth) and crappy tripple core amd 2.9 athlon cpu (intel almost twice fast). Ssao sizescale=1, sourcetexturescale=1. Fps for both mods 12, when disable ssao and reflections - 30, when disable mod - 44, when disable shadows from clouds - in range of measuring mistakes. Screenshots:

jrista hardware can't happen normally. Who want SLI support, buy me another desktop, including pc case, psu, motherboard, cpu, ram, etc etc etc, except display, so i can just throw to scrapyard this noisy heavy garbage when will move to another place.
The actual change was 8fps (the 30 to 20 was because of v-sync...with v-sync disabled, frame rate dropped from around 29-30fps to 22-23fps, so really ~7.5fps average frame rate change.) I think I figured out the source, though...see below:

About the whole FPS thing, do note that the longer you play, the more scripts that are being run and the like. You're going to get worse framerates regardless of your settings.
It's the nature of Bethesda's bastard red-headed child that is their engine.
Well, that's disheartening...hope that doesn't actually happen (as I've eliminated all known scripted mods that I used to use).
I am pretty sure though, at this point, that a significant part of (although not the whole) cause was the area I was in (along with the weather). I was near the hotsprings, with cloudy overhead and fog (from a mod) moving through, and once I moved on from that area (after making the tweaked I mentioned to SSAO scaling/quality, shadow quality), my frame rates moved back up into the 35-40fps area. I am pretty sure the increase in particles is what did my system in. I've moved to a different region on the world map now, and frame rate stays above 30fps until the fog kicks in, then it tanks again. I'd seen the fog before (from a CoT weather addon), but frame rates must have been high enough that the impact didn't take me below 30fps. I can't remove the mod (every time I've removed any mods, scripted or otherwise, my save game dies within 10-15 saves), so I'll just have to live with it.
Even
without the fog in play, if I restore my settings to what they were before, I am still experiencing enough of a frame rate drop that it takes me below 30fps on a consistent basis, and with v-sync on, I drop down to 20fps. It only seems to be a ~3fps hit in total (with all effects enabled and quality settings at -1 or 0, instead of 0 or 1), so much better... but because of the vertical stutter problem (which I know is NOT Boris' issue), I'm stuck keeping v-sync on, so 20fps is a much more common occurrence now than it used to be.
I wish there was a way to solve that stuttering problem. I'd never noticed it before with v-sync off, I am really not sure why it is plaguing me now. I remember the game used to be very smooth with ENB and without v-sync, and while FPS would fluctuate between 28fps to 45fps outdoors, it never really dropped low enough that it caused major problems. Is this issue caused by drivers? The only thing I can think of that has chanced, other than ENB, is my driver version. I must have updated a couple times over the last few months, to the latest WHQL drivers...I'd happily revert to an older version if I knew that would fix this damnable stuttering issue.
