PvP is a Minecraft modpack built around mods for player-versus-player combat, with the goal of achieving the highest performance possible. It brings together a PvP-focused selection for players who want combat mods alongside a strong emphasis on performance.
The pack includes ViaFabricPlus, which lets you join Minecraft Java servers across most versions. The author is not currently considering updates beyond 1.21.1, both because of this compatibility and because some mods are unavailable on newer versions. The screenshot in the description uses the PvP Scroutopia resource pack.
