XR700 Glitching games during gameplay

So I bought this router about 3 days ago.  First to get to the admin page (192.168.1.1) took a very uncomfortably long time and makes you wonder if you have a bad unit.  Once the setup wizard actually appears on screen the delay between screens (usually just a white page) also makes you wonder if the unit has stopped responding or if it is just taking it's time. On the .10 FW The download speed did not come up but the upload speed did and was accurate.  GUI on .10 was very muddy and not nice to navigate through and saw somewhere on a forum if .10 didn't work go back to .8 since .10 was only fixing (supposedly) a WAN drop issue.  I don't personally experience this issue with .8 so I guess I'm safe. When getting into the router's settings, when selecting NAT type on both IPv4 & 6 as open, I'm still getting test results as it being a PAR Nat - should be a full cone on open NAT.  Also setting the %'s to 70 and selecting Always for ABB we're seeing some very interesting issues in game.  We play various games in this house from Rainbow Six, Fortnite, Overwatch, etc. So lets start with Overwatch - seems to hang a bit like lag spikes, also have had times where it feels it physically pulls your character backwards or your character will continue to move in a certain direction. As far as Fortnite and Rainbow, we're noticing issues where our player will shoot on the controler or keyboard and nothing will happen.  Also reported in Rainbow where the character will glitch and also have movement issues like Overwatch.  Traffic Prioritization is set up with both Xbox, PS4 and Nintendo Switch all as Game Console as well as 2 gaming towers - Both set up for Unreal Engine and one of them again for Overwatch.  All devices in the house have been turned on at once at begining of setup to assign name and type in Device Manager. Geo Filter has been configured for 2 consoles (Xbox and PS4 in filter mode) and 2 gaming towers (in spectate mode). Geo Filter Map has been configured for our state (Arkansas) and has an Overwatch profile @ 1304mi.  Strict Mode and Auto Ping are both enabled as well as Ping Assist set to 30ms, fast search has not been enabled due to possible unwanted high latency server connections.  In settings SIP ALG has been disabled, Respond to Ping on Internet Port has been enabled in case one of our machines happens to be server in console playing.  UPnP is also enabled as well as some fowarded ports.  Lastly I have set the NTP to the correct time zone through Netgear NTP servers and checked to allow automatic adjustments for Daylight Savings.  If you see any settings that are incorrect please instruct me the correct adjustments.
