Question High Pings ONLY on Valorant.

[Shaimasu]

Been an ongoing issue for a couple weeks now, majority of the time im trying to play im fluctuating between 100-400ms. Seems like certain times of the day the pings will go back to normal(around 23ms) but always when i get off work and go to play they are sky high. I've troubleshooted with riot themselves to try and see if the issue is possibly isolated to my pc and everything they've instructed me to do didn't fix the issue, my fiance also experiences the same issues on her pc. The pings are fine on any other game so it is isolated to specifically valorant itself. I've also spoken to my ISP and they said there was an issue with something, a tech came out to fix it and the issues still persist. Currently awaiting the Tier 2 tech to contact me back to discuss with them. Wanted to see if anyone else has ever experienced this same issue, it is so confusing. Have a 500mbps down, both on LAN cables.
