The only thing that I think looks decent on VC enb is the vehicle reflections. Although, even those are quite buggy as they reflect the HUD off the vehicle. Motionblur on vc-mp provides no advantage and just causes disoreintation especially when having to quickly react where alot of spinning of the camera is involved and on top of that it blurs out the chatbox aswell. There is ambient occlusion and specular lighting on ground too, however the last time I tried them they didn't work properly as did many of the other config parameter options. Overall, the visual effects that it provided weren't worth it and no where near worth the cost in performance as the mod was causing huge fps drops at random areas for no reason, even when most of the effects were disabled.
I know that there's gonna be people in this topic that can barely run VC at default settings without fps drops and there gonna try enb... oh god the aftermath, I can't imagine. Like Darfy said your better off using texture mods, there's the Vice City Visual Enhancement pack somewhere around on this forum which I put together ages ago and since then a bunch of other visual upgrades have been released for Vice City try those, they will look tons better than these effects which look like something done post-recording in Sony Vegas.
