While playing practice mode in Tekken 7 (Steam) earlier, I noticed that when I input a diagonal command not only would it input extra commands (so with UF it would be like F,UF,F simultaneously) it would input another command similar to those when the stick returned to neutral. Is this something weird to do with Tekken 7 or a possible fault with my stick?
Try your stick with another game. Then throw the pcb out the window.
Seems fine with GG Xrd Rev 2 and SF5. Could it be an Xinput thing? I have the Mad Catz drivers installed too
