I voted no simply because 3rd parties have developed high-res packs for LFS (sure, not all textures, but getting there)
I'd rather have the devs put their time into new tracks, new cars, physics improvements, etc, than something to do with graphics. I know the new comps can handle a bunch of eyecandy, but that's not what makes this a successful simulation.
At the same time, I agree with the notion that this sim could look a lot better, but again, I wouldn't want the devs distracted with that 'issue'.
