networking – How to Bypass the ISP’s routing

I am playing a game (Valorant) where the ping to the game server is very high, about 300ms. Now, the problem is only with this particular game and most others play really well (less than 30ms ping).

So I thought the issue was with the game servers until I happened to launch the game while connected to my VPN, which was purely coincidental. With the VPN connected, the ping dropped down to 60ms! This leads me to believe that the issue is with the routing algorithm followed by my ISP. Calling them up didn’t help as they claim the ping issue is only with this and that speedtest shows the expected ping.

So my question is,whether there is a way to mimic what the VPN is doing, without the added latency and cost of VPN.

I’d appreciate any suggestions…
