Garry's Mod FAQ — Ping, Servers, Network

Yes. PingAim routes hl2.exe — the Garry's Mod process — through whichever network interface reaches your server with the lowest latency. It uses a WFP (Windows Filtering Platform) kernel driver that works at the network stack level without touching the GMod process itself. Garry's Mod uses only VAC (user-mode anti-cheat with no kernel driver), so there is zero conflict with PingAim's routing method. No injection, no process modification, no ban risk.

DarkRP lag has two independent causes. The first is server-side: DarkRP servers run hundreds of Lua scripts for jobs, entities, printers, doors, and player interactions. An overloaded server running at 10–20 server FPS processes ticks slowly, causing all physics and Lua events to feel sluggish regardless of your ping. Check with net_graph — if the server FPS shown is very low, it's a server performance issue that no network tool can fix. The second cause is pure latency: physics objects (props, money, doors) have no lag compensation in the Source engine. At 80ms+, prop interactions and door unlocks desync from what you see on screen. PingAim addresses the second cause — a lower-latency path reduces this physics desync.

Yes, the Source engine includes both client-side prediction and lag compensation, but with important limitations for GMod. Player movement is predicted locally so it feels smooth at moderate latency. Hitscan weapon shots in gamemodes like TTT use lag compensation — the server checks your hit against a history of player positions, so you can still register shots at 80–100ms without a severe disadvantage. However, physics objects, props, vehicles, and most custom Lua entity interactions are NOT lag compensated. These run purely on server ticks. This is why DarkRP and Sandbox building degrade noticeably at higher ping while TTT shooting remains playable.

Under 60ms for DarkRP and physics-heavy gamemodes — at this level, prop interactions and door physics are mostly in sync with what you see. Under 100ms for TTT and PropHunt — the lag compensation system keeps shooting and movement acceptable. Above 150ms, rubber-banding becomes visible on other players and physics interactions frequently desync. The server browser shows your measured ping to each server before joining — sort by ping and choose the lowest-latency server with the gamemode and population you want.

Because Garry's Mod uses 100% community-run servers with no Steam relay infrastructure, your ping is entirely dependent on the geographic and network distance between you and the server's physical location. A DarkRP server hosted on OVH in France will give a US player 90–130ms with no way to avoid it through settings alone. Servers in your region should give sub-60ms. The server browser ping display is accurate — use it to filter to low-ping servers before committing to a community.

No. Garry's Mod community servers connect you directly to the server's real IP address — there is no Valve relay infrastructure optimizing your path. This means your route from home to the server is exactly whatever your ISP provides. It also means GMod server IPs are visible publicly on BattleMetrics and GameTracker. Tools like PingAim can see and route your hl2.exe traffic directly, with nothing hidden behind a relay layer.
