I know there's been many posts about this, but I genuinely cannot fix this problem.
My tablet is a Ugee s640, I've been playing with raw input enabled just fine until today.
I'm genuinely stressing as I can't play with 1x sensitivity and I physically cannot even fix my 'work area' on the tablet drivers.

If anyone knows how to help PLEASE reply I'm desperate.

May you tell us what exactly is the issue without raw input? Why can't you adjust your tablet area in driver?

I really have no idea on why I can't adjust my tablet area, it simply won't work :[
Also the only issue without raw input is really the sensibility of the pointer.. I can't play with a really seemingly slow pointer

you shouldn't be using raw input with tablet, it can break some stuff. Use your tablet drivers instead to make adjustments, and don't touch the in-game sensitivity slider

If it's a problem with the tablet driver then try reinstalling it, and also don't use raw input.

I already mentioned I can't use my tablet drivers as they don't work. I am aware I can't use raw input yet it worked perfectly until the day I made this post..
I've tried reinstalling my drivers multiple times and it just won't work

lets fix the core issue as to why your tablet drivers dont work. What drivers were you using. Were you using the official drivers from the Ugee website? Were you using OpenTabletDriver?
