Cutting Gaming Latency Without Hardware: Network Optimization for ISP-Locked Connections

While most gaming optimization guides focus on hardware upgrades, this project reveals that network-level tweaks can deliver dramatic latency improvements even on ISP-locked connections. For gamers constrained by ISP-managed gateways and limited router access, practical techniques—from DNS switching to QoS marking—prove that 192ms latency cuts are achievable through OS-level configuration alone. This approach demonstrates that expensive hardware upgrades aren't always necessary for responsive gaming.
