Project ENB lowers framerate by about 30 fps

Recommended Posts

I can play Skyrim at around 47 or 48 frames per second. But when I got project enb, which is supposed to have a low impact on performance, my fps drops to about 18. On performance option D I had about 23-25 fps, and on option E (Extreme Performance) I had about 28 fps. Since Project ENB is supposed to have little effect on your performance, I think it is a bug (or driver incompatibility).

My specs:

Intel Core i7-4770 CPU @ 3.40 GHz

16 GB RAM

64-bit operating system & processer

4GB VRAM (NVIDIA GeForce GT 640)

Windows 8

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!
