Better KI? No there isn't a package of 'good' mods .
I found this when googling for real car names, never used it so I can't tell you if it works or not:
The link still works
The blood mod from the link I gave you is pretty bloody yes. But it's not that unrealstic. The excessive blood you see on the screenshots is only when you keep shooting a corpse. If you just shoot someone once it'll be a pool of blood and a blood stain on the spot where you shot him.
As for the difference between patches, a few minor things were changed:
· fixed a bug causing tree leaves to look transparent
· fixed a bug that prevented uploading of rendered videos to Social Club when attaching certain music tracks
· fixed for clip capture "OFF" slowdowns occurring when near water's edge
· exposed "detonate" in custom key mapping options menu for Grand Theft Auto IV: The Lost and Damned so users can remap "down" arrow key
Most mods are compatible for both patches however , but most of them have been optimised for 188.8.131.52. Like Icehancer for example. I use 184.108.40.206. myself and never experienced any problems with mods made for 220.127.116.11.
I don't know about the newest icenhancer, never tried it . I'd say try a few different ones out to see which one you like best. Just make sure you have a backup that you can place back every time you want to uninstall one.
