Note
Do not use HDR and SMAA whit ENB, not compatible, 
I suggest to tewak ini in this way and not allow FRAMERATE manager of OBlivion reloaded


iMinGrassSize=120                             (if you set OFF Grass in  Oblivion Reloaded)                
        uGridDistantTreeRange=15 or 20        ( whit 150 % trees dimension it's more than enought )   
                        uGridDistantCount=25  or 36                 ( if you have a lot of mods could be better save memory for them ) 
                     iShadowMapResolution=512 or 1024     (vanilla oblivion set this to 256 whit last patch but can cause CTD )
 bAllow30Shaders=1                                                                                                             
bUseWaterDisplacements=0                                                                                               
                                                                                        
GET Other values from Oblivion Reloaded Page
TURN WATER RIPPLE OFF INGAME. ( YOU NEED FOR USE ENB + OR )

About the ingame options, like distances of objects and actors i suggest THIS

100% of value if you have a light modded oblivion, expecially whitout many HD textures model and not many
45-60% of those valors if you have a Heavily modded oblivion whit lot of textures, many actors and creatures and ect.
this way you should play whit a nice quality at 45-60 fps whit AO and shadows.


THIS ISNT A FAULT OF YOUR PC, YOU CAN HAVE BEST PC OF THE WORLD, THIS IS A FAULT OF OBLIVION ENGINE, YOU CAN DO MANY LITTLE THINGS FOR THAT, MANY LITTLE MOD AND PATCH, BUT NO WAY TO HAVE THIS PERFORMANCE WHITOUT GIVE BACK SOMETHING, REMEMBER U ARE PLAY A 2007 GAME

Step 2

Danload Candid Enb and copy main folder content to your oblivion folder, override when asked, then Select ONE settings from white and normalcolor folder and put it into your Oblivion Folder, override if needed , there are more / less performance settings based on quality and ambiental Occlusion and the same perfomance settings for Candid normal and for strongly altered color version ( strongcolorwhite folder ), Detailed Effects Used in All versions are below videos.

Step 3

Open Your oblivion.ini file, check your resolution on this tags.

iSize W=****
iSize H=****

write those value somewhere, then go to your oblivion folder, open effect.txt.ini ( if u hide the file extension it's named effect.txt ) and search for that tags, the put it the values you got in your oblivion ini ( your resolution, in few words ) save it and now you should play fine.

Step 4
Now Your need to set those parameters in oblivion/data/shaders/OblivionReloaded folder ini filed for those shaders

Fov

100 (105 FOR SCREENSHOTS)

Water

reflectivity      = 1.9
 
Coloring

Strength      = 0.70
Saturation    = -0.25

After it rember to set ingame WATER RIPPLE options from videomeno to off, (ripples will be provided by or, if u use it you will get a water bug from enb)

All following modes are installed in this order, and overriden the previous texture when asked, it's like a priority line

1 QTP 3 Redimized Or QTP 3 Full

2 Landscape Retexture

3 Cave retexture

4 Ayleid ruins retexture

5 Fort Ruins Retexture

6 Rocks Retexture

7Sewer Retexture

8 Signpost Retexture

9 Hi resolution Varla and welkynd stones

10 Better Staff texture

11 OCO v 2 ( Oblivion character overhaul )

seems can affect your FPS, Read carefully how to install and patch it for costum body mesh, personally i found v 1 less fps affecting, so if you want look for it on nexus

12 Painter Painting Textures

13 Fantasy Nightsky number 1

This mod it's AMAZING

14 Oblivion Grass Overhaul

A must

15 Improved trees and Flora 2

15.1 Improved doors and flora

16 Oblivion Trees overhaul

IMPORTANT NOTE: Oblivion trees overhaul it's a beta, it's a not final, and change enought your oblivion appearence so look screenshots of mod before installing
it's just an option, many of my firends find it nice, i never tested it

17 Ho res Tree Canopy Shadows

Another must

18 TD Rome IC replacer

i love this mode but has a japanise description only so search carefully for dawnload botton, it's just a texture replacer

19 StradaCittàImperiale

Another nice retexture for IC streets

20 Animater water v 3

Change a lot waterfall appearence and power, i like a lot old version, check what you like.

21 Enhanced magic effect

After installing the moode you choose for your game start Oblivion Mod Manager, go on utility tab on right side of obmm vidow, go into archive invalidation
then deactivate all tags o activate only tags that i mention, BSA Alteration, Textures, Generate Only on hash Collision and then give Update. now you should play fine whit all texutres that you have choose.



Other mods That i like and change appearance

1 All Natural

NOTE : for this enb i raccomand no real light version and it seems all natural have a little fps drop

2 Immersive interiors

NOTE (Sometimes can have CTD goingt into and out interiors, but this happen really rarely, to me at less )

3 Personality Idles v 4 modified version

Top of the Top, really give life to persons and your own character, allowing it to make some movements when he isnt moving, whit many poses.

4 Mass outfit redesigned

NOTE : That mode can turn oblivion into a like-skimpy game and i wont it, i like reasonable flavour version, where fems are properly suited whit armors and not so much exposed, of this mod and i deleter the arena armor file on my own pc because was too skimpy, anyway it's player choice
