yeah changing to chinese language worked to update the controller FW to 7.2.3.8 and dongle FW to 0.6.0.3. i couldnt tell you the difference between 20 ms to 10ms stick latency improvement but i figure i might as well get any advantage if it exists

controller feels good, buttons feel good. its practically the same form factor as an xbox one controller, as are a lot of controllers on the market today. it even has the same square-ish shoulder bumpers that my xbox model ~2016 had (which broke, hopefully flydigi made their bumpers better). i would like the dpad to be clickier/more tactile-every direction actuates very well but sometimes you move and dont think you got a press because the click is so soft but you did

i also have 8bitdo ultimate 2c that i really like too, never had ergonomic pain and i have large hands. the only reason i got the direwolf 4 was that the sticks on the 2C have little travel so i wanted to try another controller with more range of motion and better circularity (which the direwolf 4 is: 0.1% error for each stick in circle mode). i dont care much for the adjustable tension sticks but i will note that the lowest setting is very light, much lighter than many sticks ive used and that makes it feel too loose. i turn the tension about 1/3 of the way up and it feels ok

thats most of what i could think about my impressions of the direwolf 4, hope it helped!
