Keyboard input lag (Logitech K270 wireless keyboard, Windows 10 20H2)

Hi there. I've got yet another Windows 10 problem. lol

This time it's my keyboard. I'm using a Logitech K270 wireless keyboard, on Windows 10 Pro 20H2. I have been experiencing keyboard input lag off and on for a couple months now, and I've searched for possible solutions, but none so far have worked. I was hoping you guys could suggest some fixes.

Here's what I've tried, based on the suggestions I've found on the web:

• Updating the keyboard/dongle's drivers (there are no drivers on Logitechs's site, oddly) and firmware. Nope.
• Swapping USB ports. Nada.
• Unplugging any extraneous USB devices. Zilch.
• Checking the batteries. No joy.

As I was typing this it was lagging here and there. It's a bit disconcerting. Anyway... I don't think I missed anything, but if you need more information or diagnostics, lemme know and I'll upload 'em.

I am at a standstill at what to do and would really appreciate some help. Thank You!

 

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?
