No cause the majority if his points are agreed and well worn and the only one that matters, physics he seems to have a preference opinion over anything objective like the FFB articles Amar had posted
Thomas Buchta (Fanatec) says this on GTPlanet:
Good explanation. I might want to add that this XID protocoll is only better in theory. In practice most games use only force commands (left and right) because they are used to program FF effects that way from PS3 or PC games. Therefore the technology is not fully exploited yet. But the protocol is already better because of the additional support for vibration motors.
The reason why our wheels are a bit more expensive is that we made two independent sets of electronics into the wheel to get support for two consoles. This technology is pretty tricky and certainly the most advanced on the market today. Beside that you even have the option between wireless and wired on PS3/PC.
So XID is technically better, but developers used to HID will struggle with it. That's fair and valid, but we are talking T10 and FM, where XID is there only FFB option and clearly their primary market for wheel users..
I only see a great deal of subjectivity in people's FFB assessments, but there are some simple objective tests and a general acceptance of the following
1. Forza has a good torque element modelled in FFB, take a FWD car and launch on full throttle with wheel spin.. you get torque effects. Do the same on GT, and it's non-existant
2. Take a FWD car on a constant radius long corner and build speed to gradually increase slip angle, in Forza you get an amplified FFB effect as the slip angle increases, in GT you get very little
3. There are many vibration effects in Forza (engine, kerbs, etc), these aren't possible on HID devices (and thus GT)
4. Track feedback (suspension feedback) is rather subdued, it's not missing completely, but it's clear that T10 concentrate on the tyre FFB with just rudimentary suspension FFB
I can't see a technical reason why (for example) XID is responsible for the difference in FFB that exists between the games, it's more a design decision..
What you want is a game with both tyre FFB and track FFB at the same level, and so far Assetto Corsa seems to do that exceedingly well..
