I’ve been having some issues with several games in the past months, I recently figured it was a problem with my ISP, but Cloudflare WARP solved it in all my games except on Last Epoch.
When I have Cloudflare WARP active, I cannot play Last Epoch. Infinite loading screens and then a connection error.
Without Cloudflare, I average 180ms on most games, and with it I get around 80ms so it is really life changing.
