This is a problem that I've been trying to fix for ages..
A stutter that occurs when a new sound is played that causes the game to freeze for roughly a second and the map redraw.
The frustrating thing is that it seems to be a common problem but there isn't a common fix.
For me, the stutter disappears when I mute the game but obviously this isn't an ideal solution. It's clearly not a graphics problem.
I have a V15 Nitro laptop. I've uninstalled and reinstalled all my drivers including sound (realtek) and hard drive drivers to no avail. I've installed the game on both ssd and hdd to no avail. I tried windows system repair which didn't work.
I will point out this problem isn't exclusive to CM however, it's just more noticeable than in other games.
If anyone has found a fix for this extremely annoying problem, please share.
Cheers
