Just noticed this today- had never been an issue previously…
Got the screen doing a jitter thing- and I thought bugger!
Reloaded an earlier game - still there…
Started a new game - still there…
Awesome. Either the patch did this, or…
A wee bit of troubleshooting, revealed to me during cutscenes and ingame cinematics- the game wasnt showing xbox controller buttons (what I was using), rather keyboard shortcuts.
“Got it!” I thought!
My wacom (interactive mouspad) was feeding back mouse movements.
Looks like KCD in newer versions, keeps input registrations from all devices… whilst earlier versions allowed swappong controls easily; I would guess that newer versions is ‘more generous’ to multiple inputs.
Maybe unplug the mouse or at least rest it somewhere where it doesnt register a surface.
Might be the same with any joysticks etc left plugged in for keyboard and mouse players…
This is a fix for some.
Removed screen jitter bugs for me.
Hope this helps others too.
