Arma Reforger is a demanding milsim, and a dedicated server has to simulate AI, vehicles and large player counts smoothly. Undersize it and you get rubber-banding and low server FPS. This guide covers the real Arma Reforger dedicated server requirements.<\/p>\n

The short answer<\/h2>\n\n\n\n\n\n\n\n
Players<\/th>\nRAM<\/th>\nCPU<\/th>\n<\/tr>\n<\/thead>\n
Up to 32<\/td>\n8 GB+<\/td>\n4 fast cores<\/td>\n<\/tr>\n
64<\/td>\n16 GB+<\/td>\nHigh single-thread CPU<\/td>\n<\/tr>\n
64\u2013128 (heavy AI)<\/td>\n16 GB+<\/td>\nTop-tier single-thread<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n

The server executable uses roughly 3 GB of RAM just on startup<\/strong>, climbing as players and AI join. AI-heavy Game Master scenarios push CPU far harder than the player count alone suggests.<\/p>\n

CPU is the bottleneck<\/h2>\n

Like most simulation games, Arma Reforger’s server is CPU-bound and leans on single-thread speed<\/strong> \u2014 the simulation, AI and networking run on limited cores, so raw clock speed matters more than core count or extra RAM. A server can have RAM to spare and still drop server FPS if the CPU can’t keep up with the AI and tick rate.<\/p>\n

What drives the load<\/h2>\n
