Expert Guide: Running Quake Live Dedicated Server on Windows

Running a Quake Live dedicated server on Windows is still possible and reliable in 2026 if it’s configured correctly. This exclusive DrTechLog guide is based on real-world experience, long-term community practices, and common pitfalls that are not documented officially.

This article goes beyond basic setup and covers:

• Proper SteamCMD installation
• Steam support (Steamworks DLLs)
• Server configuration best practices
• Autorestart & crash handling
• Performance fixes (100% CPU bug)
• Firewall & port forwarding
• Workshop map limitations on Windows

Summary

Requirements

Before starting, you should already understand:

• Basic Windows administration
• How SteamCMD works
• Port forwarding & firewall rules
• Basic server configuration files

You will need:

• A Steam account that owns Quake Live
• Windows 10 / Windows Server 2016+
• Stable internet connection (VPS or dedicated machine recommended)

Step 1: Install Quake Live Server Using SteamCMD

1. Download and extract SteamCMD
2. Launch steamcmd.exe
3. Log in using an account that owns Quake Live

login your_steam_username

4. Install Quake Live server files:

app_update 282440 validate

5. Install Steamworks SDK Redistributables:

app_update 1007 validate

Once completed, Quake Live will be installed under:

steamapps\common\Quake Live

Step 2: Enable Steam Support (CRITICAL)

Without Steam support, your server will:

• Not appear correctly in Steam server list
• Fail workshop integration
• Reject some client connections

Fix:

1. Navigate to:

steamapps\common\Steamworks SDK Redist

2. Copy all .dll files
3. Paste them into:

steamapps\common\Quake Live

This step is mandatory.

Step 3: Server Configuration

Go to:

steamapps\common\Quake Live\baseq3

You’ll find:

• server.cfg
• access.txt

Recommended server.cfg additions:

set sv_hostname "DrTechLog Quake Live Server"
set sv_maxclients "16"
set sv_fps "40"
set g_allowvote "1"
set g_inactivity "0"

Fix “Unpure client detected” error:

Add at the bottom of server.cfg:

set sv_pure "0"

⚠️ IMPORTANT WARNING

DO NOT set or uncomment:

net_ip

This option is bugged on Windows and may:

• Prevent server from appearing online
• Block direct connections

Step 4: Starting the Dedicated Server (Hidden Command)

Quake Live does not have a visible server executable.

Instead, it uses a hidden launch parameter:

+set dedicated 1

Basic launch command:

quakelive_steam.exe +set dedicated 1

Recommended batch file (high priority):

start /wait /abovenormal quakelive_steam.exe +set dedicated 1

Save as:

start_server.bat

Step 5: Fix 100% CPU Core Usage Bug

If the server runs for many hours/days:

• One CPU core may spike to 100% usage
• Happens even when server is empty

Solution: Auto-restart every 24 hours

Auto shutdown script:

@echo off
cls
title Quake Live 24h Shutdown
:loop
timeout 86400
taskkill /IM quakelive_steam.exe
goto loop

Auto restart script:

@echo off
cls
title Quake Live Auto Restart
:loop
timeout 10
start /wait /abovenormal quakelive_steam.exe +set dedicated 1
goto loop

Use the restart script as the main launcher.

Step 6: Prevent “Quake Live Has Stopped Working” Popup

When Quake Live crashes on Windows, a popup appears waiting for user input.
This blocks auto-restart scripts.

Fix via Group Policy:

1. Run gpedit.msc
2. Go to:

Computer Configuration
→ Administrative Templates
→ Windows Components
→ Windows Error Reporting

3. Enable:

Prevent display of the user interface for critical errors

No reboot required.

Step 7: Firewall & Ports

Make sure these ports are open:

Windows Firewall:

• Allow quakelive_steam.exe
• Allow inbound & outbound UDP

Workshop Maps on Windows (Reality Check)

⚠️ Important limitation:

On Windows dedicated servers, Steam Workshop integration is unreliable.

Common behavior:

• Maps load locally
• Clients are NOT auto-downloaded maps
• Console shows:

WARNING: Skipping workshop, ISteamUGC is NULL

Current workaround:

• Manually copy .pk3 files to baseq3
• Ask players to subscribe manually

For full Workshop support, Linux servers are strongly recommended.

Stability & Performance Tips

• Use SSD storage
• Avoid VPN tunnel interfaces
• Set server process priority to Above Normal
• Restart every 12–24 hours
• Avoid excessive mods

Final Notes

Despite being unofficial and partially legacy, Quake Live dedicated servers on Windows still work well when configured correctly.

For:

• LAN servers
• Community servers
• Testing environments

Windows remains a viable solution.

Q1: Can you host a Quake Live dedicated server on Windows?

Yes, Quake Live dedicated servers can still run on Windows using SteamCMD, although Linux is more officially supported.

Q2: Why does Quake Live server use 100% CPU?

This happens when the server runs for long periods. Restarting the server every 12–24 hours fixes the issue.

Q3: Does Steam Workshop work on Windows servers?

Workshop maps may load locally but usually won’t auto-download for players on Windows servers.

Q4: Which ports are required for Quake Live servers?

UDP 27960, UDP 27950, and Steam ports like 27015 must be open.
