About this image

Since ENB for Oblivion was never updated to modern standards I went the route of ReShade.This screenshot is with effects enabled.

I'm on an 'ancient' 970 GTX and my performance is good.

The enabled effects are:

- PD80_02_Cinetools_LUT.fx
- qUINT_mxao.fx

I think no other AO is on par.
It does also include IL (Indirect Lightening).

- FXAA.fx]
- ASSMAA.fx
- PD80_02_Bloom.fx
- PD80_03_Filmic_Adaptation.fx
- PD80_04_Contrast_Brightness_Saturation.fx

- PD80_06_Chromatic_Aberration.fx

The beauty of this shader is that it has access to the depth buffer,
meaning you can decide which part of the scenery it is applied to. 

Here's my detailed settings:
