Haven’t been playing for awhile, and got motivated after I upgraded to Win10… I have an older rig (but it checks out!) - I5-2500K, GTX670, 16GB - and because my monitor is even more crappy at 1680x1050 it’s always been just fine. Anyway. Last night I noticed that on busy maps I was getting lots of stuttering but it didn’t feel like network lag and my framerate was still good. So I look at task manager and my 4 cores are all maxed out, then break it down by process and FIREFOX is using 49% of my CPU with BF4 using about the same. So I closed out battlelog/Firefox and the game smoothed out, with about 80-85% CPU usage. But of course then if I wanted to switch servers or anything, I had to restart it. Not a HUGE deal, but has anyone else had similar issues? Is it the plugin that’s causing such high resource consumption or is it Firefox itself? I switched from Chrome to FF because Chrome was doing such a bad job of resource management lately, but this could send me back if it will work better for Battlefield. ---

I had the opposite impression… Overall I thought win10 was running most things and especially games more efficiently than 7 or 8. ---

microsoft are pushing their win10 down people’s throats with that ‘free upgrade’ from win 8 to win 10, i had fps stutter a while ago on bf4, after recently updated my drivers to the 355 version of the nvidia driver the stutter was completely gone, i still lag on 64 man servers but other than that it runs silky smooth on 60 fps, i dont think win 10 offers anything win 7/8 doesnt except maybe someone monitoring you ---

> i dont think win 10 offers anything win 7/8 doesnt except maybe someone monitoring you This is FUD. Windows has had backdoors in it for a very long time now. They really didn’t need to give you a free operating system to monitor you.
