I bought in 2022 for 780r to replace the X7 of the older model, because. wanted to put macros on LMB. Regarding the 3 "core" - it quacks very successfully, there are a lot of instructions on the Internet. I use the bloody3 program: in some places the translation is lame, but it is clear what is at stake and, most importantly, it works. Macros (a well-known sequence of movements, for example, like damping recoil) are written in a very convenient editor and you can immediately go to test, then put it on the LMB and clamp it without worrying about mmofps. I have already collected a whole library of macros and switch between them as needed. And yes, the stock recoil dampening function was not useful, because I play with Y inversion and the mouse, on the contrary, starts to move upward.
