Battlefield problem with Logitech wireless KB+M
So, here's the problem;
When ever i play Battlefield 4 for an hour or more, my Logitech wireless peripherals start lagging, or should i say micro-freezing. Sometimes they can freeze for a second or two. This was obviously game-breaking with the mouse, so i had to go back to my wired mouse. The problem was solved with that. The freezing still persist with my wireless keyboard, however, but it's not that bad since it doesn't affect my aiming in any situations.
The reason i'm posting this here is because i'm 99% sure it's caused by either Origin or Battlefield (or maybe even the browser plugin?). This does not happen with any other game i play. After i close Battlefield when it has started happening, i've noticed that both setpoint.exe and dwm.exe are eating a constant 20% CPU usage (total 30-40%)! I can only stop them from doing that by rebooting (waiting doesn't help). That does not happen in any other circumstance than after i've played a session of Battlefield. I'm not sure if this is related to the freezing, but over-loaded setpoint.exe seems to indicate that it's propable.
This also happened with Battlefield 3 with my older PC build. I used the same wireless Logitech devices back then too (K360 keyboard, M505 mouse, 1 Unifying reciever).
PC specs:
Intel i5 4670K
8GB DDR3 RAM
NVIDIA GeForce GTX 670
Windows 7 x64
i use Chrome browser for Battlelog. all latest updates and drivers.
EDIT: Killing dwm.exe from task manager seems to fix the bloated setpoint.exe and dwm.exe. dwm.exe relaunches automatically and both files act normal again.
