@rkrisi I didn't have the issue, and I don't use Windows 10. I'm glad you solved the problem, I've seen that fix mentioned on reddit, and I still don't like windows 10. Hopefully they come up with something more complete and less invasive in privacy. I'm still with a vulnerable Windows 7 setup with backups.
Maybe I should go through these 71 updates pending. There's now new "Security and Quality rollup" updates, those should be fun... Instead of one update, now I have to open the KB linked for sereval updates, on each rollup update. I don't want tracking / telemetry updates.
It's about 40-50 now. I'm seeing many security updates that look nice to install. The others however... well, I've hidden some already! Don't wait a year to update your system, I just had 12 successful updates and 47 fail!
I have the same issue, there is a lag spike every second like clockwork in many games, especially those that use VR headsets. This is on a NVIDIA 980 TI card. It took me awhile to track down but it's definitely flux doing it, I can reproduce it 100% of the time.
