I've just started playing this, having snapped it up on the Steam sale, and the whole tone of the graphics is utterly souless, brown, grey and muted. I don't remember GTA IV being quite so lacking in colour, but it's not on my PC right now, so I can't compare. I'm guessing this look and feel is entirely intentional - but can anyone else confirm please?
Yeah it's intentional, there's an extra grain filter and some colour filters slapped on for good measure. If I remember correctly you can turn them off in the graphics options.
