I want to buy the GS850-X as my first wheel but i dont know that this one is compatible. Does someone know this and can give me an answer?
That wheel appears to be listed as a PS4 and XBox wheel. It doesn't seem to be advertised as a PC compatible wheel. Therefore I cannot guarantee it will work in a PC. I suspect it will work as a generic xbox controller, but that's only my guess and I may be wrong.
Just as a recommendation, it looks like it costs around the same as a used G27 which is a 100 times better in every way. You get way more for your money, and pretty much any game supports it. Just something to consider.
it's also only 270 degrees. which is bad. any good wheel is 900 degrees some maybe more. just like Zero said, get an used g27 or g29. just because something is cheap, doesn't mean it's good value.
