Got a BISS-C upgrade kit from TOMO last Friday. I like it. I have it running in 22bit mode even though FW 0.9.8 does not officially support it. Using the exact same iRacing Car and Track with identical settings, I do notice a slight better feel in the smoothness. Whilst driving I was trying to put my finger on what exactly the difference is. And a bit smoother was all I could come up with. Not very scientific I know. I shot some video for a review I am doing on the conversion and when I look at it compared the video in my recent OSW review, I can see that my steering corrections are not as abrupt or quick as when driving the SinCos encoder. It felt like I was driving slower, but my lap times actually went up by 3 or 4 tenths. I was not expecting that based on sensations I was getting through the wheel. And this with my motion full on. Which usually slows me down a bit.
Based on what real information I can get from this testing, I don’t think this is a placebo effect. I always remind myself to be aware of that effect when I am testing something new. Of course 3 or 4 tenths could also be the result of my just being a better driver for this session. Not as much caffeine intake yesterday! lol.
But there is, for me, a noticeable change from the SinCos encoder. Albeit a subtle one, that I am enjoying. As always, YMMV…And I will be playing with settings and other games moving forward as time warrants.
