Versus Pre Search Ping settings,

Online Versus games use a peer to peer connection. This means your ping is limited by who you connect to. With Online Versus being less popular than modes with dedicated servers (WoC, HUT), the best match may be someone in another region. Which would increase the ping. It's also very possible that the population is going to increase during peak hours. A larger player pool will probably mean you'll match with someone closer and have a better ping.
