Waiting hours for a game to install is genuinely painful especially when you just paid for it. The good news is most slow installations are fixable with the right settings. Here’s every trick that actually works, in order of impact.
First Understand Why It’s Slow
There are two separate speed problems and most people confuse them. Downloading is getting the compressed files to your PC installing is decompressing, verifying, and writing them to the correct directories. You can have gigabit internet and still wait an hour if your storage drive is slow.
Your storage drive is almost always the real bottleneck not your internet connection. Fix both and you’ll see a dramatic difference.
Tip 1 Move Games to an SSD Immediately
This is the single most impactful change you can make. Upgrading from an HDD to even a basic SATA SSD is the most significant quality-of-life improvement you can make for your gaming rig it not only speeds up installations dramatically but also reduces game loading times.
Here’s the real-world write speed difference:
| Drive Type | Write Speed | Impact |
|---|---|---|
| HDD (7200 RPM) | 120–220 MB/s | Bottlenecks gigabit internet on large installs |
| SATA SSD | 450–530 MB/s | Handles any consumer internet speed |
| NVMe SSD (PCIe 4.0) | 3,000–7,000 MB/s | Never the bottleneck |
If you’re downloading to an HDD and your speed fluctuates between fast and zero that’s the drive struggling to keep up, not your internet failing. Steam downloads data faster than the disk writes it, causing repeated pauses while the disk catches up.
Tip 2 Keep at Least 15–20% Free Space on Your Drive
A full drive installs games dramatically slower and most people don’t know this. When an SSD or HDD fills up past 85% capacity, write speeds degrade significantly because the drive has to work harder to find empty blocks.
You also need breathing room for installation itself. You need roughly 3x the game’s final size as free space for download, decompression, and installation to complete. A 100GB game needs about 300GB free during installation plan ahead.
Tip 3 Add Your Game Folders to Antivirus Exclusions
Antivirus is silently throttling your downloads and it’s one of the most common hidden causes of slow installs. Antivirus programs deeply scan all network traffic and disk writes in real time this analysis overhead severely throttles Steam downloads. Add folder exclusions for your Steam installation and game library directories to prevent scanning and restore full speed without disabling protection.
Here’s exactly how to add the exclusion in Windows Defender:
- Open Windows Security → Virus & Threat Protection
- Click Manage Settings → Add or Remove Exclusions
- Add folder:
C:\Program Files (x86)\Steamand your game library folder - Never exclude just Steam.exe scanning happens during file writes, not just on the executable
A real case: One user had 972Mbps internet showing only 2.7Mbps download speed in Steam adding the steamapps folder to antivirus exclusions fixed it immediately.
Tip 4 Disable Metered Connection
Windows secretly throttles downloads on connections it marks as metered. Windows 10 and 11 mark many connections as metered by default especially Wi-Fi and mobile hotspots which caps background download speeds.
To fix it: Go to Settings → Network & Internet → Wi-Fi → your network → Set as metered connection → Off. This one change alone can double download speeds on affected connections.
Tip 5 Use Ethernet Instead of Wi-Fi
Wi-Fi introduces packet loss and inconsistent speeds that directly slow down installations. Ethernet provides optimal download speeds Wi-Fi does not always provide the full speed your internet connection is capable of.
Even a cheap ethernet cable makes a measurable difference especially over long installations where Wi-Fi signal fluctuations compound over hours.
Tip 6 Change Your Download Region (Steam)
Steam download servers get congested during peak hours and major sales switching regions fixes it. The closer the servers are to you, the more bandwidth they can use but during congestion, a server in a different time zone can actually be faster than your nearest one.
How to change it: Steam → Settings → Downloads → Download Region → pick a different country. Start downloads late at night or early morning to avoid server congestion or temporarily change your Download Region to a region in a different time zone with less traffic.
Tip 7 Set Process Priority to High
Force Windows to give your game launcher more CPU and network resources. Open Task Manager → find your launcher (Steam.exe, EpicGamesLauncher.exe) → right-click → Go to Details → right-click again → Set Priority → High.
This forces your system to prioritise the download process over background apps competing for resources. It’s especially effective on lower-end machines where CPU is also a bottleneck during installation.
Tip 8 Close Everything Eating Bandwidth
Background apps silently consume your internet while games download. Check if other applications are using your bandwidth watching high-resolution videos on YouTube while downloading a game affects the speed significantly. Other applications might also be downloading updates in the background.
Close or pause these before starting a big installation:
- Browser tabs (especially video streaming)
- Windows Update (pause for 7 days in Settings)
- OneDrive and Google Drive sync
- Discord (it updates silently)
- Any other game launcher with pending updates
Tip 9 Clear Your Download Cache (Steam)
Corrupted cache files cause most unexpected download slowdowns and failures. Go to Steam → Steam Menu → Settings → Downloads → Clear Download Cache. This removes corrupted temporary files that cause most download failures and slowdowns.
Do this first if Steam suddenly starts downloading slower than usual it’s the fastest fix that requires zero technical knowledge and takes under a minute.
Tip 10 Disable Streaming Throttle in Steam
Steam silently caps your download speed when it detects streaming activity and most people never know. This setting is enabled by default and silently caps Steam’s download speed whenever Steam detects an active Remote Play session, in-home streaming, or broadcasting. Unless you actively need smooth streaming over fast downloads, turn it off in Settings → Downloads.
It’s one of the most common hidden throttles on fast connections and it’s buried deep enough that most users never find it.
Tip 11 Disable VPN During Downloads
VPNs add extra routing and encryption overhead that directly slows down game downloads. VPNs add extra routing and encryption overhead which slows downloads pause or disable your VPN while downloading and whitelist Steam in your firewall.
If your VPN actually makes downloads faster that means your ISP is throttling unencrypted traffic. Run a speed test with and without VPN if VPN speed is 50% or more faster, your ISP is throttling you and VPN is actually the right tool to use.
Quick Reference Tips by Problem
| Your Symptom | The Fix |
|---|---|
| Download speed fluctuates between fast and zero | Storage drive can’t keep up move to SSD |
| Fast internet, slow Steam downloads | Add Steam folder to antivirus exclusions |
| Downloads slow at certain times | Change Steam download region or download overnight |
| Speeds fine, installation still slow | SSD upgrade HDD write speed is the bottleneck |
| Download keeps stopping randomly | Clear Steam download cache |
| Wi-Fi download slower than expected | Switch to Ethernet cable |
| Everything else normal, still slow | Disable metered connection in Windows |
| Streaming and downloading simultaneously slow | Disable streaming throttle in Steam settings |
The honest priority order: SSD first, antivirus exclusions second, close background apps third. Those three changes fix 90% of slow game installations on Windows everything else is fine-tuning on top of a solid foundation.
