Known Lag Problems
These problems are reported by real players. If your region or ISP is listed, a network optimizer is likely to help.
Southeast Asia / Oceania
150-250ms to nearest major server regions- Very few GMod servers hosted in SEA — most available servers are in Europe or US
- Australian and NZ players face 200–250ms to EU servers and 150–200ms to US servers as baseline
- SEA players connecting to European DarkRP servers experience severe prop desync at these distances
- Community servers in AU/SEA tend to have lower player populations
South America
120-200ms to US East- Few GMod servers hosted in South America — most are US-based
- Brazilian players typically see 150–200ms to US East servers
- Some South American ISPs route inefficiently through Miami adding extra hops
What players commonly report
- DarkRP server lag from too many Lua scripts and entities (server-side CPU overload)
- Prop desync and physics lag on high-ping connections
- Workshop addons downloading in background causing lag spike on first join
- Budget community servers running on home connections or underpowered VPS
- Tickrate mismatch causing choke (server running at 33 Hz, client requesting 66 Hz updates)
How to Fix It
Try these first — they're free and solve the problem for most people.
01 Check your actual ping with net_graph
1. Join any server 2. Press the tilde key (~) to open the console — if it doesn't open, go to Options → Keyboard → Advanced → Enable Developer Console, then press ~ 3. Type: net_graph 1 and press Enter, then press ~ again to close the console 4. A small overlay appears in the bottom-right showing ping, loss, and choke 5. For more detail, type net_graph 4 — this shows incoming/outgoing packet rates too 6. Watch the 'ping' and 'choke' values — choke means the server is dropping your packets due to rate mismatch
Confirms whether your issue is network (high ping or choke) or server-side (low server FPS shown in the overlay). Essential first step before trying anything else.
02 Pick a server in your region with good ping
1. From the main menu, click 'Find Multiplayer Game' (or press F2) 2. The server browser shows your measured ping to each server before you join 3. Click the 'Ping' column to sort by latency — green is under 60ms, yellow is 60–120ms, red is over 120ms 4. Filter by gamemode (DarkRP, TTT, PropHunt) using the dropdown on the left 5. For DarkRP specifically: sort by players to find populated servers, then check if ping is acceptable before joining
The single biggest fix. Switching from a 180ms server to a 40ms server of the same gamemode eliminates prop desync and rubber-banding immediately. Many players join popular servers without realizing there are closer alternatives.
03 Switch to a wired Ethernet connection
1. Connect a Cat5e or Cat6 Ethernet cable from your PC to your router 2. In Windows: Settings → Network & Internet → Wi-Fi → toggle off 3. Your PC switches automatically to the wired adapter 4. Reopen GMod and check net_graph — jitter (ping variation) should drop significantly 5. If you must use Wi-Fi, sit closer to the router or use 5 GHz band instead of 2.4 GHz
WiFi adds 5–30ms of jitter. In Garry's Mod, jitter causes prop positions to stutter and Lua events to arrive out of order. A stable wired connection matters more than raw ping in physics-heavy gamemodes.
04 Tune cl_updaterate and cl_cmdrate to match the server
1. Open the console (~) 2. Type: cl_updaterate 66 — this asks the server to send you updates at 66 Hz (only works if server tickrate is 66) 3. Type: cl_cmdrate 66 — this tells the server how often you send commands 4. Type: rate 786432 — sets your max bandwidth usage to ~6 Mbps (safe for most connections) 5. If the server is 33 Hz (common on DarkRP), set both to 33 instead of 66 6. You can check server tickrate with: status in console — look for 'tickrate'
Mismatched cl_updaterate and server tickrate causes 'choke' — the server drops your excess packets. On a 33 Hz DarkRP server, asking for 66 updates/second wastes bandwidth and increases apparent jitter. Matching values eliminates unnecessary packet loss.
05 Close bandwidth-heavy background apps
1. Press Ctrl+Shift+Esc → Task Manager → Performance tab → Open Resource Monitor 2. Click the Network tab → sort by 'Total (B/sec)' to find what's consuming bandwidth 3. Common GMod killers: Steam downloading workshop addons in the background, Windows Update, Discord video streams, cloud sync (OneDrive, Google Drive) 4. Right-click Steam in the taskbar → Downloads → Pause all downloads before joining a server 5. Pause Windows Update: Settings → Update & Security → Pause updates for 7 days
Garry's Mod downloads workshop content on first join, which competes with live game traffic. Pausing Steam downloads before joining a new server prevents the lag spike that many players experience in the first few minutes on a server.
Regions with good connectivity
Players in these regions likely won't benefit much from a network optimizer.
- Western & Central Europe — Germany (~1,100 servers), France (~700), UK (~600) provide dense server coverage. Frankfurt's DE-CIX internet exchange gives most EU players sub-50ms to German servers.
- Eastern US / Canada — ~1,400 US servers. East Coast players typically achieve sub-40ms to the nearest US server. Well-connected through major US IXPs.
Still lagging? The problem is likely your ISP's routing to the game servers.
