The improvements had a very significant effect on it running on my 'puter. Everything seemed to 'work', and it was a pleasure to use. I think the interface looked much less distracting since I've played Hikki before; even better, all the buttons work. I didn't however find an 'unassign' button which is still an inconvenience.
With the same graphics options as with the first full Hikki release, but this time using the crossfaded sound system the driving experience seemed much much improved. FPS appeared better (didn't actually check), driving smoother, and I could hear what the car was doing. The FFB remains too clunky in my opinion, getting my wheel to budge from the centre is heavy work, and immediately after some invisible point is reached it goes completely light, even if not understeering.
I fancy this release is much better than the previous, yet, I'm not ready to invest in it. FFB doesn't work for me, and if there's one thing I miss oh-so-much in NKP it's head/view shaking and moving with G-forces and bumps. LFS feels so much more intense with the head shaking all over the place while desperately looking for a place to pass..
