Latency issues when gaming after Windows 10 update, anyone else?

So my system was running kind of ok before the Windows 10 update. Sure, the Killer 1535 wasn't giving me the best performance, but it was manageable. After the windows 10 update however everything went bad. I'm getting decent ping when doing speedtest and even in the games server browsers I'm getting good ping, but once I jump into a game, any game, I get really bad ping spikes which just teleport me all over the place. I've tried resetting my router several times, restarting my system, seeing if any settings were interfering with it or if windows firewall was blocking anything but I couldn't find any solution. The only change here is the windows 10 update.

I have an Intel 9260 underway which should be arriving soon so I can see if that fixes the issue, but I was wondering if anyone else is experiencing these issues after the update and if they managed to solve it.

 

Is the killer 1550 better or is it just a driver issue with the whole range?

 

Killer 1550 uses the same drivers as the Intel 9260 since they're essentially the same exact chip. The 1535 uses Quallcomm/Atheros chips and has different drivers.

 

Oh okay. So why doesn't everyone just get the upgrade from Dell when buying the new range. Surely that's cheaper then buying a new chip and throwing the old one?
