I had the same issue, and just the "dxgi.dll" from the System32 folder did the trick.

I got the following issue with Rudy ENB - Natural (0.249) for Fallout New Vegas.

Notice the Shadows disappearing at the edge of the screen. It's mostly noticable when the Sun is low.

I noticed the Fallout ENB doesn't have:
Does that mean it can't be run with the games Anti-Aliasing?

Not sure if it has been asked before or is even possible.

It would be nice if SubSurfaceScattering had Interior/Exterior seperation.

I'm currently using Phinix ENB (0.246), but i'm unable to adjust the Evironment Settings. No matter what value i use, nothing changes ingame. For example changing the following: AmbientLightingIntensityInteriorDay=0.63 AmbientLightingIntensityInteriorNight=0.63 to AmbientLightingIntensityInteriorDay...

Decided to stay with Pure Waters.

WATER is conflicting with too many Mods.

Planning to switch from Pure Waters to W.A.T.E.R, but is the particle patch still compatible?

The W.A.T.E.R files are for 1.6 and the Mod is at 1.75 (Final) atm.

It's not compatible with SMIM anymore.

Some files are no longer SMIMed when using this with SMIM 1.47.

I'm facing the following issue.

As far as i know this didn't happen with 0.198.

EDIT: Fixed it already, it's related to EnableParticleLights, setting this to "false" fixes it.

Man this 0.198 works wonders compared to 0.197.

No more stutters with ReduceSystemMemoryUsage=true and currently hitting 3051 MB VRam without crashes =]

Can finally play Skyrim without having to Fast Travel due to stutters =]
