The Forza Horizon demo works flawlessly with this... IF you play around with the expert settings. To me, it feels amazing if i change the outside steering deadzone to 70 and the outside handbrake deadzone to 65. Also, on this wheel, the rumble is MUCH better than with the controller (lots of people reporting weak to on-existant rumble when playing with the wireless controller - i tried it, and it's true, the game feels dead on a wireless controller). Night and day.
The DEMO also doesn't force you to use RB or LB at all. But then again, there are no paint options in the demo, so who knows. Browsing the map and driving doesn't need the bumpers in any way, so the Speed Wheel is great for it.
If you're wondering about Forza Horizon, it's a definite buy with the Speed Wheel. The game itself being filled with invisible walls (and i'm not talking about the demo-only walls - those are easy to spot since they're marked blue) is a pain, though. It's not an open-world game AT ALL. So don't expect anything like TDU from Horizon. It's more like Burnout Paradise, Hot Pursuit "open".
Also, guys, i would REALLY appreciate if anyone could do a good report on the NEW (2012) Need for Speed: Most Wanted, in a few weeks. They say the handling is new and not (the tank-heavy) Hot Pursuit handling, so i'm dying to know how it feels with the Speed Wheel. Hot Pursuit was very responsive with the wheel, but the handling was so boring in it. The game only felt OK when you were drifting (weaving and just plain driving felt sluggish and heavy as hell). I'm hoping it feels better... and that it has rumble (The Run and Hot Pursuit were responsive with the Speed Wheel, but neither had rumble - while NFS Shift was responsive AND had amazing rumble with it... probably the best rumble you can get in this wheel).
Thanks so much for your suggestions on the settings for the wheel on FH. I was getting pretty discouraged on the stock settings, but switched to yours and went to cockpit view. Wow. Quite an experience. Can't wait to pop in Forza 4 on this nifty little wheel now.
