Makes me wonder how big the difference between the ultimate and the pro is.

same here, wondering if I did the right choice moving from Sc1 OSW small mige to Sc2 Sport, I mean it should be better but I am waiting to see if the upgrade was worth.

I have to agree with the feedback here on the Ultimate. My online friends all thought I was nuts because I already had the Big Mige. If you haven’t tried a Ultimate you cant explain it to someone. It just does everything better is the only way to explain it. And I agree 100% with StefVR on the smoothness of it and how close it feels to a real car. Catching slides is like second nature you don’t think you just react like you would in real life. Granted you cant save them all but ive definitely saved some I know I wouldn’t have with the OSW. Knowing it will only get better from here I have no regrets buying it.

Second that.
Beano, didn’t you get Pro version too?
The only feedback on moving from SC1 (Lenze) to SC2 Pro was from @McErono, and not sure he was that super impressed.
Yes Andrew, I will test and feedback on the Pro after I return from travels in a couple of weeks. From my quick experience with it, it is also a very good step-up from other DD wheels, incl. Podium, Bodnar and OSW.
Of course, as with every other wheel, use the new wheel for a few weeks, then step back to your old wheel and evaluate the situation then

Can someone test the SC2 Ultimate with RFR-WheelTest soft and show us the diagram?
http://www.racingfr.com/forum/lofiversion/index.php/t48669.html
Other than latency, not sure what is really useable on that diagram. Other than bragging-rights…
There is a useful window for acceleration required from a servo solution to satisfy the needs of our sims, anything more is a bit silly and not useful at all, to the contrary.
Cheers,
Beano
Latency I would like to know.
I can test when I get home on the weekend…but perhaps someone else can test sooner…

If anyone wants to test that, please do the test with the filters off to be comparable to the other devices.

Yep, agreed, otherwise results will be skewed

Could you please do the rfr wheel-test with the SC2 Ultimate? For comparison, here are some results from MMOS (Beckhoff reducted so not direct driven), SC1 (small mige 10000ppr), SC2 Pro and Fanatec DD1.

Wow. Such bad values for Fanatec?
Or which are good and which are bad values?
this test is not accurate for anything really.
If I understand correctly, these tests are trying to show raw caracteristics of motors/electronics ; that is why they are done without any filters. That’s not exactly how you are supposed to use these wheels in real case scenario even if good performance is related to good FFB. All these wheels might work way below their full potential for the best ingame simulation value. This tests cannot evaluate the benefits of the software.
The Fanatec show a very strong acceleration, but seems behind the competition with latency. The curb present some overshooting, maybe it is partly due to the shape of the steering wheel attached (F1 2018LE)?
@Mika, could you please develop why it is bad and what would be a good test?
there are computer-specific variance in usb latency, also depends on what other usb devices are connected. Also, the friction of the overall system affects the initial acceleration somewhat, making variances especially to the latency measurement.
Also the rim being used has an effect, although that is smaller effect with DD wheels.

Ok for the usb part, but could you please tell me what is described in the “overalll system”?
Aren’t Direct Driven wheels supposed to have negligeable friction? I am wondering about the actual influence of the friction here because the belt driven Beckhoff with VSD+STM32+MMos (non-integrated) shows a latency of 2.09ms (so less than SC1 and SC2Pro) and because the Podium DD1 shows as much latency than a belt-driven CSW V2.5 (around 20ms).
In the end, what type of test should be representative/fair? The same test with the various motors on the very same PC, without any other USB devices than mouse and keyboard and without any steering wheel attached? Or a way to measure latency at different points and not only at the start of command until the initial acceleration?
This test is not accurate? Can you prove it somehow or you just guessing? Ppl use this test for years so good to know why you think so…
GD did their own extensive testing in various servos so I would imagine that they have a well established set of testing criteria that they drew on.
Once the results are finally published we will hopefully have a much better idea on the differences found between them all.
Mika already gave some feedback above as to why, here is a comment I made on the same topic on iRacing also. Just because people have been using the test for years, doesn’t make it any more meaningful or accurate.
[quote] To be totally fair, like said on GD forums too, we cannot use these tests in random environment like this, way to many variables.
The only way to conduct these would be in a controlled environment - same pc, same USB ports used, same Windows environment, as well as same wheel-rim, as wheel-dia and relative weight will all massively impact these results. For example, I have a small 4nm 60mm Mige servo here that can run 1000rpm at 48Vdc that will destroy any other servo on that list posted on GD wrt acceleration, I will guarantee that…but, as a DD wheel, it is totally useless.
Anyway, I have mentioned to Thomas during my early beta testing that I thought the wheel was to active and sitting on the limit wrt stability, what we call quarter-wave damping tuning… that response-behaviour confirms it to some degree, but it is something that can be corrected by proper low-level tuning.
Again, above just a simple observation, like said, if you want meaningful results, it might be much wiser testing all servos in same environment, perhaps even without any wheel-rim attached, then we might be able to draw conclusions from that.
But, in reality, there are better ways to test the response-behaviour from the servos themselves, as well as isolate the performance of the drive-controllers, USB HID et al…these software test-progs are not good enough and results will need to be taken with a bag of salt ![/quote]
