Pretty significant thing about Retpoline and this performance patch - it only works on Broadwell and OLDER Intel CPUs. It does not work on Skylake or newer.

It works on all AMD CPUs.

To be fair skylake and newer had 'better updates' so were not as badly affected by the impact of the code changes from what I've seen.

This is nice for me though, my i7 4790k should get a bit of it's performance back, which would be nice as I actually noticed the drop in performance when I did a reinstall which included the patches...

Bottom line, my PC, and others, went from a crawl, back to almost normal speed. My PC was slow as a snail before this update. glad they corrected the speed issue. I hope INTEL pushes out Their GEN 10 Procs soon.

Wow, other than the perf. improvement my temps also dropped by 10 degrees after this update - no other system changes - at first I thought my fan controller had gone squiffy but once my monitoring software launched it was like Phil Collins was in there, looking to sacrifice

Ever since I recently upgraded to 10 pro, i no longer get asked what to do when a usb or dvd is inserted, tried all the answers in a google search with no luck, would this fix it?

Seems after this update my wife's notebook started work faster, but I still see sometimes "Disk load 100%"

All this update did for me was introduce mouse lag into all Infinity Ward releases I own making them unplayable.

I spent hours updating drivers, reinstalling software and updating the BIOS trying to work out what had happened. I then discovered a reply to a thread on Reddit, removed the update and everything is right with the world again.
