My ENB setting for GTA 3, for which I spent many hours adjusting, the task was to make a good ENB, but so that it would not strain the eyes, respectively, motion blur, depth of field, was disabled or minimized.
There are very cool reflections, but sometimes the interface on the car can be displayed, but this does not interfere with the gameplay so much. Very cool SSAO lighting and shadows, trees have reflections, both on the asphalt and on the car.
In general, the graphics are very much transformed before the eyes. Also found a suitable timecyc. It is also recommended to use it together with 2dfx.
SSAO and others are enabled at F10, disabled by default.
It can eat up performance, requires a mid-range graphics card, was tested on GTX 1050ti, load can reach up to 90%, so I can't guarantee stable FPS on cards weaker than 1050ti. Also, a minimum of 1 GB or more of video memory is required.
