ENB Performance Tweaked As Much As I CAN! Results Here.. BTW 2160p Screenshots..

[toxsickcity]

Hi,

 

I play with ENB on my 4K display, Wanted to Share some findings to try and get ENB Playable!

 

I also go to the extreme and create a Custom Resolution with REGEDIT, and create 3500x1800 and makes my game play in a black border.. not so bad.. a 1 inch border.. and makes my FPS go from 28FPS to 35

 

I have a i7 4820K @ 4.6GHZ 16GB DDR3 2400MHZ and

R9 290X O.C.

 

Without ENB i get 48fps-65fps on 3840x2160 skyrim Ultra INI settings.

 

when ENB ON! REAL VISIONS FULL QUALITY A,

I get down to 15-18FPS

 

I have spent a lot of time and found that editing the following items in ENB Settings (SHIFT-ENTER) & Skyrim/skyrimprefs.ini in Documents/my Games/Skyrim folder of your computer

 

try the following for better performance and MINIMAL impact of graphical Quality..

 

search for these in skyrimprefs.ini

bDoDepthOfField=1-->0

fShadowDistance=8000.0000 -->4000.0000

iShadowMapResolutionSecondary=1024-->512

iShadowMapResolutionPrimary=2048-->1024

iShadowSplitCount=4-->1

fLeafAnimDampenDistEnd=3000.0000-->1500.0000

fLeafAnimDampenDistStart=2600.0000-->1300.0000

fTreesMidLODSwitchDist=10000000.0000-->1000000.0000 (1 zero removed)

bShadowMaskZPrepass=1-->0

iShadowMapResolution=2048-->1024

 

Those settings were best impact when modified.. you can take my settings which are after (-->)

or try lowering even more..

 

in ENB itself.. try the following to gain performance even more then the INI tweaks...)

 

in SSAO, Untick Enable complex

in Skylighting, change filter quality to low

in shadow, turn use bilateral to off.

reflections, change filter quality to low.

reflections, untick enable exterior..

water, shadow quality to low

 

I found these settings improved performance the most with minimal impact on quality...

all other settings can be left HIGH.. as I perfer to keep quality and I found these settings didnt alter issues too much

 

lastly.. I did something extreme.. makes graphics look a little out of whack but liveable and gives best FPS Gain.. you can change to your prefs...

 

in Engine settings of ENB (Shift Enter)

ForceAnisotropicFiltering=true

MaxAnisotropy=16-->2

ForceLodBias=false-->true

LodBias=0-->-0.7 (Minus 0.7)

AddDisplaySuperSamplingResolutions=false

EnableVSync=false

VSyncSkipNumFrames=0

 

The Idea here is (removing anisotropy) which was giving me 4-5fps gains

when enabling Negative LOD and forcing ansio... to 2 gave in my opinions great results visually..

 

After all the bullshitting around.. I had where standing on bridge in RiverRun looking at water wheel.. into distance..

Was 15.9-17 FPS, now.. I get 26-28FPS

 

NOW NOTE... My screen is 4K and at this resolution the game LOOKS VERY SPECIAL even after the changes I made.. So truly the changes were minimal in my opinions and I will run around a little more to see if I can see any bad graphics.. but my little run around yesterday looks fine..

remember 2160 vs 1080 I'm unsure of results for your system... but this works well for me.

 

 

YUK!!! ENB OFF!

Skyrim 3 ENB OFF

Instructions to make CUSTOM RESOLUTIONS..

this usually allows extra FPS if you don't mind playing on a smaller size of your screen... or fullscreen NOT DOT for DOT imaging.

 

I Have AMD Hardware, perhaps Nvidia is different...

 

OK,

2 ways to do this..

for a full-screen custom resolution & custom refresh rate, we can EDIT EDID (Method 1)usually allowed to make 4 Of them aside from monitor defaults... usually leaves 2-3 to edit because need to keep NATIVE and don't change that!

or Method 2, Registry edits.. safer and quicker

 

Method 1

Using CRU (Custom Resolution Utility)

 

notes;

* use automatic timings (automatic -LCD Standard)

* set only resolution after settings timings

* change refresh to anything else then change it back to your preferred

* only edit porch,sync,blanking if expert.

 

after making your resolution be sure to restart your PC.

 

 

 

 

I perfer

Method 2.

 

REGEDIT Way. for AMD users.

Goto your catalyst control,-->information, -->software.

2D driver path...

remember it!

open regedit.exe

navigate there (note the 000x changes for every new driver installation so check it often)

DALNonStandardModesBCD2

 

open it..

you will see such as...

0008 12 80 07 68 00 00 00 00 (thats a resolution (1280x768))

to create a custom...

I have made BOLD the part to edit.

so for a resolution of 3500x1800

do

35 00 18 00 00 00 00 00

 

then exit regedit

restart pc or just log off then log on again

check your control panel for your new res...

 

NOTE cannot make resolutions higher then Native! (native is whats supported by your screen)

 

NOTE 2, Using method 1 creates Fullscreen resolutions with overclocking abilities.. (eg making a refresh rate of 65hz for 1080p) (i have 120 & 125hz 1080p on my 4k Screen) because 4k is 30HZ :sad:

 

NOTE 3, Using method 2, allows the screen resolution to have a border making the image Perfect 1:1 (Dot for Dot)

Clearer look..

 

NOTE 4, If the Method 2 gives you a full screen image which is blurred a little, check catalyst control panel for

MY Digital Flat-Panels->Properties

Make sure enable GPU scale is OFF, or chose maintain aspect ratio/use centered timings.

Playing around now with your skyrimprefs.ini settings using RealVision ENB. I'm hoping for minimal visual impact but still keep the great look and definitely increase my fps.

 

I'll let you know how it goes.

 

Thanks for posting!!!

BTW ... I'm not quite ready to mess with my screen resolution yet. I also have a 4k display but I doubt my GPU can keep up. I currently play at 1080p.
