I heavily modded GTA IV without any problems, never ran out of memory or occured crash, but in EFLC I can't spawn a single modded car.. When I spawn modded car, it keeps loading and city textures start dissapearing till there's nothing left to show (usually happens within 3 minutes). I'm using the same scripthook/cleo as in GTA IV. Both games are up to date (steam).
I tried using various commandlines, didnt help.
