I can't get post processing to work. No DOF, just color correction. Using SKSE and Steam

@Boris
Is it normal that enabling Reflections causes a render speed drop even if for the camera no reflections are visible and rendered @ all ?

even if i do a console->fov (no value, default) so the entire render scene becomes visible the drop stays the same and the only change in the scene i notice is some change on the water surface in the distance (color change) but no reflections anywhere else being rendered in that specific landscape scene.

What i mean by that the Render speed lose vs the Visual result looks strange without Reflections in that Scene it renders @ 57 fps if i enable reflections it goes down to 17 fps and even without image based lighting i notice 0 difference only with image based lighting i see that color change on the distance water surfface.

That Render Speed drop is even heavier then SSAO, though im not testing with my own ENB but another users one

perern, I have this issue every once in a while. Usually a restart will fix it.

CruNcher, reflections can cause large FPS drop for me. SSS, SSAO and Skylighting seem to affect Reflections, so try lowering/disabling those and see if the FPS raises with Reflections on.

I disabled all of them in this ENB via the in ENB GUI the Render speed drop stays the same and as i said without Image Based lighting no difference is visible @ all (except the huge drop), though im not sure if this is generic for ENB Reflections or a Render Layer issue of the Specific ENB here yet have to test with the default ENB first.
But yeah im aware that Reflections are one of the most computational heaviest complexities in Rasterization though i just wondered that the drop is so huge even if no effect is visible @ all on screen, especially without image based lighting which only triggered some visible change.

Reflections computed on entire screen, except cases when amount of reflection from material is zero or it's the sky. Filtering is applied to entire screen anyway. Screen space reflections are slow, because they have very bad caching because of different directions per pixel and they use raytracing in depth, also not fast math.

[CruNcher]

I guessed that the Reflection property for the Material is it's specularity right or is there a specific property for the mesh and or texture that defines it ?
I might have missed it when you introduced Reflections in ENB but how to get a Material to cast a Reflection or is it just happening in specific situations like Windows where the light hits the ground and water surfaces ?

[ENBSeries]

Reflection amount is got from material color (don't remember, but it have specular color i guess) and from texture (alpha channel for some materials, for other it's separate texture as specular amount).

[CruNcher]

Ok i guess you would have showcased it if it would be possible todo a Player reflection on the water surfface so i guess it isn't possible ?

[ENBSeries]

I didn't water modifications yet, so too early to ask about it.

I see btw i tried another ENB and with this the Render drop with Reflections Enabled isn't as high just -3 fps got lost for this scene where the other ENB lost those 30 fps so 10x Render drop for 0 visible effect in that scene very strange
I'll keep a close eye on this, not sure what the differences yet are in these 2 very different preset behaviors with Reflections.
