Windows 10: Horrible M&K input Lag

Ive had this problem for years, ive tried basically everything to fix it and its a massive problem when playing games such as call of duty, i talked to some people at microsoft, some said to get rid of corrupted files and some said to reinstall windows, has anyone else had this problem and if so what did you do to fix it?

Horrible input lag on Forza Horizon 4.

I am experiencing horrible input lag in Forza Horizon 4. Whenever I press A or D, it takes a few seconds for the game to actually react. And some other times, it keeps steering to the left or right despite me not holding any key at all. How do I fix this
issue?

 

x1900xtx input lag

Ok I have the same issues with the input lag when using ati tool and the dynamic fan control. I only use ati tool for this feature so my question is this: does the latest version address this issue and if not, can I control the fan speed a different way that wont cause the stupid input lag? The x1900xtx get HOT and I like ati tool, but it is hard to play css when you have input lag for 3-4 seconds every 2 minutes. Please help me ASAP. Does .26 version fix this or what are some suggestions that might eliminate the input lag but still be able to use this great tool? Thanks! Does anyone know if ati tray tool works better in this department?

 

Input lag?

• So I had to install the last fall creator's update because of mandatory security updates. Sometimes I launch tf2 and there's major input lag while other times there isn't. I used to have a solution of reverting to a version before the fall creators update
  but I've tried that recently and I needed to reinstall Windows 10. Another solution was to just restart but I don't want to have to restart my laptop every time I want to play video games. I don't know what's causing the input lag, whether it's because of
  the game or the OS or Logitech Gaming Software (which might not be the issue since I had this issue way before I ever got a logitech mouse). I suspect it's the OS and the fall creator's update. I need a permanent solution to stop this input lag. If anyone
  has one, I would really appreciate it.
