How to Speed Up Steam Downloads: 12 Fixes
Steam downloads can be frustratingly slow, but you can usually fix it by changing a few settings, clearing the download cache, or adjusting your network. This guide explains the most effective ways to speed up Steam downloads, from simple in-client tweaks to router-level changes, and what to do when nothing seems to work.
Why Steam Downloads Are Slow
Steam downloads depend on several factors: your internet connection speed, the load on Steam’s servers, your disk’s write speed, and the settings inside the Steam client. A common misconception is that Steam limits your download speed by default—it doesn’t, but it does have a bandwidth limiter that can be set too low. Also, Steam often shows download speeds in megabytes per second (MB/s) while your internet plan is advertised in megabits per second (Mbps). One byte equals eight bits, so a 100 Mbps connection can download at about 12.5 MB/s at best. If you see a number close to that, your connection is likely fine.
Check Your Internet Connection First
Before changing Steam settings, confirm your baseline speed. Use a reputable online speed test and compare the result to your plan’s advertised speed. If the test shows a much lower number, the problem is your network, not Steam. Restart your modem and router, and try connecting your PC directly to the modem with an Ethernet cable. Wi-Fi, especially on the 2.4 GHz band, can be significantly slower and more prone to interference than a wired connection. If you must use Wi-Fi, try the 5 GHz band and make sure you have a strong signal.
Change Steam’s Download Settings
Steam has a few settings that directly affect download speed. Open Steam, go to Settings > Downloads and review the following:
- Download Region: Steam connects you to a server near your location. If that server is overloaded, switch to a nearby region. Go to the Download Region dropdown and pick a different one, then restart Steam.
- Limit bandwidth to: Make sure this is set to No limit. If a limit is active, Steam will cap your download speed.
- Clear Download Cache: This option removes cached files that can become corrupted. It forces Steam to re-download some data, but it often fixes stuck or slow downloads. After clearing, you’ll need to log in again.
Pause and Resume the Download
Sometimes a download gets stuck in a slow state due to a temporary network hiccup. Pausing the download and then resuming it can force Steam to re-establish the connection, often resulting in a faster transfer. To do this, go to your Library, click on the game’s download progress bar, and press the pause button. Wait a few seconds, then press resume. You can repeat this a few times if the speed doesn’t improve.
Close Other Programs and Games
Steam downloads compete with other programs for bandwidth and disk I/O. Close any other applications that use the internet, such as web browsers, streaming services, or other game launchers. Also, make sure you’re not playing an online game while downloading—that will split your bandwidth and slow both activities. If you have a mechanical hard drive (HDD), defragmenting it can help, but for solid-state drives (SSD), defragmentation is unnecessary and can reduce its lifespan.
Adjust Your Router and Network Settings
Your router can also be a bottleneck. Here are a few things to try:
- Enable QoS (Quality of Service): Many routers have a QoS setting that prioritizes certain types of traffic. Set your PC as a high-priority device to give Steam downloads more bandwidth.
- Change DNS servers: Steam’s download speed isn’t directly affected by DNS, but a slow DNS can cause delays in connecting to download servers. Try using a public DNS like Google (8.8.8.8) or Cloudflare (1.1.1.1).
- Update router firmware: An outdated router can have bugs that affect performance. Check your router manufacturer’s website for updates.
- Disable VPN or proxy: If you use a VPN or proxy, turn it off. It can add overhead and slow down your connection.
Check Disk Health and Free Space
Steam needs to write the downloaded data to your disk. If your drive is nearly full or failing, downloads will slow down. Ensure you have at least 10-20 GB of free space for the game you’re downloading. You can also check your disk’s health using tools like CrystalDiskInfo (for Windows) or the built-in Disk Utility on macOS. If your disk is healthy but still slow, consider installing games on an SSD instead of an HDD—SSDs have much faster write speeds.
Frequently Asked Questions
Why does Steam say my download speed is lower than my internet speed?
Steam displays speed in megabytes per second (MB/s), while internet plans are usually in megabits per second (Mbps). To convert, divide your Mbps by 8. For example, 100 Mbps = 12.5 MB/s. If you’re seeing a number close to that, your connection is fine. Also, Steam’s servers might not always deliver the maximum speed, especially for popular game releases.
Will clearing the download cache delete my games?
No. Clearing the download cache only removes temporary files used for downloads and updates. Your installed games remain intact. You will need to log in again, and some settings may reset, but your game library is safe.
Why is my download speed slower on Wi-Fi than Ethernet?
Wi-Fi is subject to interference from walls, other devices, and distance from the router. Ethernet provides a direct, stable connection with lower latency and higher throughput. For large downloads, a wired connection is almost always faster and more reliable.
Does Steam throttle downloads?
Steam does not throttle downloads by default. However, it may limit speed if you have a bandwidth limit set in settings, or if the server you’re connected to is under heavy load. Changing your download region can help avoid overloaded servers.
Can I download games faster by using a VPN?
Sometimes, but not usually. A VPN can help if your ISP is throttling Steam traffic, but it can also slow things down due to encryption overhead. It’s worth trying, but don’t expect a major improvement in most cases.
Why does my download speed fluctuate during a download?
Fluctuations are normal. They can be caused by network congestion, server load, or your ISP’s traffic shaping. Pausing and resuming the download can sometimes stabilize the speed.
