Ok, Now i've finally successfully installed Realvision ENB with Realistic lights and almost all the suggested mods. First I tried the game without ENB running. Of course it runs pretty much rock solid on 60fps with everything on Ultra, AA and all those goodies on max, LOD settings max'd and on 2560x1600 resolution. I'm playing games like Shadow of mordor with same result, 60ish FPS with ULTRA settings not much problems.

But as soon as I turn on ENB for Skyrim I'm getting about 5-12 FPS, Which is no secret.. It's not even playable, It doesn't seem to matter what i do the FPS stays below 20 anyways. I have all the ini files set up correctly and performace tweaks done. Optimizations here and there, plus running the game at only 1920x1080 with ENB.

Now I do know that ENB consumes FPS, but isn't this a bit too much? It cut my fps down to about 1/10th on a much lower resolution. Anyone got a sollution for this?

I'm running the game on the following system


* Intel core i7 4930K (6 core) @ 4.5Ghz + Corsair Hydro H100i Watercooling
* 64GB (8x8GB) Corsair DDR3 Vengeance Pro Series Silver 2133Mhz
* Asus Rampage IV Extreme Black edition
* 2x Samsung 840 Pro 256gb SSD (RAID-0)
* 2x MSI Radeon R9 280X 3G Twin Frozr (Crossfire)

Windows 8.1

Test the game without Crossfire. Does it work better?
Have you disabled driver memory manager? It seems to suck with AMD.
Maybe it's because too many objects are visible which make the ENBSeries cry when it tries to process every effect for every object like SSAO and other not so noticeable shit. This happens for me in Riften Jail (20FPS vs 60 FPS with vsynch on), have to check later why.

Check this thread, BTW: http://enbseries.enbdev.com/forum/viewtopic.php?f=23&t=509

FYI, just installed Realvision ENB just to test it for you. I have Corei3-550@3.84GHZ, 4GB RAM@1600mhz, ASUS Radeon R9 290x (driver version 14.7 beta 3 [14.20.1004-140811a-174673E]), SkyrimHD1K + SDO + D3DOverrider + UGridsToLoad=7 + other shit no one cares about. Traveled through the main roads across Skyrim for one hour with god mode. Minimal was 25 FPS.

UPD 11.11.2014: omg, я лох, turned off forceborderlessfullscreen, everything is now over 45-60 fps w/ vsynch.

It's all about AMD and crossfire. For the first case i don't know, because had test videocard more than year ago and performance was fine at that time, so the f* up drivers or hardware recently.

I am INFP, not the brutal, godamnit.

Seems the drivers are bad. For example, for some reason the ones greater than version 14.7 RC3 can just make the OS to crash at ANY goddamn unexpected time (this is an ill-fated, well known problem). You can try this 14.7 RC3 version, which seems to work fine and not to call BSODs.
