Did the rawinput function exist in the earliest version of CS2? Is there any convincible source of this?

I can feel that the rawinput was enabled by comparing the in--game movements from changing settings of Windows Mouse Setting part and I knew that the angel movements are unaffected from WIndows Mouse Settings.

But is there any other convincing sources like game pack documents or configurations where I can see that there is a readible texts/codes proving the functioning rawinput mechanism in a solid way?

I would like to give a 10USD tip if anyone can explain for me in a detailed way.

If you're thinking about when they went from CSGO to CS2, then CS2 has always had raw input enabled.

Here's an old video I made for CSGO comparing raw input on and off to rinput.exe which was supposed to be better:

CS2 has always behaved like m_rawinput 1, and the option doesn't exist anymore.
