I upgraded my i7 2700K CPU / z77 xtreme motherboard to a MSi X470 Gaming Plus motherboard / Ryzen 5 2600X CPU with 16GB Corsair Vengeance ram. Everything runs perfectly. I get a ton of frames in games with no lag, except each game has something wrong with it. In League of Legends I rubber band for the first like 2-3 minutes of the game for no reason. When I run World of Warcraft, ALL my background processes lag (i.e if I'm watching a YT video on my second monitor it will continuously stutter as long as WoW is my main program, if I alt tab it does NOT lag anymore). Sound does NOT lag though and WoW never losses frames or latency even when running in the background.
This is a problem because I stream and do recordings and I can't keep OBS open with video games as it will stop responding / lag out when running in the background, as well as discord and teamspeak do as well.
I have tried doing a fresh install of Windows 10, and I have made sure ALL drivers are updated for everything and my BIOS are updated. I'm not using any beta drivers what-so-ever.
