all i know is no overclock an xim on 1000hz feels way different then pc overclocking controller to 1000. thats the thing about the xim an how interesting it is. thats why i do enjoy the few people on these forums that do have the programs or equipment to truly test these things. they may say the xim is overclocking it which it is to a degree but when i put the xim on 1000hz it says in my program the xim interval is 1-4(ms) meaning i think its polling at 1000 but possibly still capped to 250? hence the 4(ms) in there. its still more responsive then just having the xim at 250hz which then program says the controller interval is at 4ms. but when i overclock it then its at truly 1000hz i believe because then it says the interval is at 1(ms) but i could be wrong but they definitely feel completely different.
