Starting last night, seemingly unprovoked, every time I use one of the selection wheels my ping spikes and I get INSANE input lag.
Same here. I posted in a similar thread with what I've tried. No idea what's causing it.
Hey I have these issues also, can you try going into windows and disabling the "game mode" and report back if that worked for you?
I tried it and I was able to play through a game last night with no lag.
Obviously this is a pc fix if that is your platform.
