I'm getting horrendous latency in games as well
I play
Call of Duty: Modern Warfare
Overwatch
World of Warcraft
League of Legends
Rainbow Six: Siege
Speedtest wise I'm getting the full speeds I'm paying for.
My computer was recently kitted out with new components such as Motherboard (which means new Network card) etc and the cable used is a Cat 7 so I know for sure it's not my computer or setup.
None of the devices that are used for gaming use anything less than a Cat 7 Cable.
All devices are fully up to date with network card drivers etc
I eventually want to upgrade to Gig1 but while my connection cannot be used for the main purpose it was purchased for I'm not going to do so.
