How Many GB Is Destiny 2 on PC? Install Size and System Requirements (2026)

As of October 6, 2026, Bungie's storage article lists Destiny 2 on PC (Steam) at 180.90 GB, and the official minimum specs are Windows 10 64-bit, 6 GB of RAM and a GeForce GTX 660 2GB-class graphics card. Steam's own store page still shows 105 GB, which is a leftover line from 2020 rather than today's number. This guide explains why the two figures differ, what the 353.00 GB pre-load number really means, and how to check your PC against the requirements, PC only. If you also plan to record while you play, the recommended specs guide for game recording covers the extra headroom to think about.

Official minimum and recommended specs (same on Bungie and Steam, PC)

Short answer: use Bungie's 180.90 GB

If you download through Steam, plan around the 180.90 GB in Bungie's storage article. Bungie itself says these numbers are not exact and that the install size varies by installed languages, with the listed size being the maximum, so your actual folder can come out smaller. The 105 GB on Steam's store page carries a note that it applies as of November 10, 2020, so do not use it for free-space math. The 353.00 GB figure adds the currently installed version (up to 172.10 GB) to the Update 9.7.0 pre-load (up to 180.90 GB), which is a one-time situation rather than the everyday footprint. If a full drive leaves no room for recordings, recording bitrate and file size comparison shows how bitrate changes file size.

How to check storage and fix a stalled install

1. 1Match the store you actually use — Bungie's table gives a different number per store. On the PC rows, Steam is 180.90 GB (353.00 GB while pre-loading), Epic Games Store is 180.65 GB (352.56 GB), and the Microsoft Store is 181.76 GB (181.76 GB even when pre-loading). For the installed size, the gap between the largest and smallest store figures is about 1.1 GB (calculated: 181.76 GB minus 180.65 GB), but use your own store's row when you do the math. Console and mobile figures are left out here.
2. 2Read your PC specs with dxdiag — Type dxdiag into the taskbar search box and open it to launch the DirectX Diagnostic Tool. As Microsoft describes it, the System tab's System Information shows your operating system, processor, memory and DirectX version, and the graphics card name is also shown in the same tool. On a first run it may ask whether to check that drivers are digitally signed, and Microsoft recommends answering Yes. Then compare each value with the table above.
3. 3Compare against free drive space — Check that the drive you will install on has more free room than your store's row. When you pre-load a large update, Steam can need up to 353.00 GB for a while. Bungie warns that without enough storage you may hit download or install problems and may need to delete or uninstall files. It publishes no recommended extra free space and no SSD requirement, so none is added here.
4. 4Start with Bungie's Steam guide if it stalls — Bungie's Steam guide says to install from your Steam Library once the game is on your account, and points install problems to Valve's update and installation article. It also suggests accepting all operating system and driver updates and clearing the Steam download cache when Steam or Destiny 2 misbehaves. Steam Deck and Proton are listed as unsupported unless Windows is installed and running.
5. 5Remember when the numbers get refreshed — Bungie says the storage tables are only updated for major updates or content releases. The values checked here reflect the state after Update 9.7.0 on June 9, 2026. Update 9.7.0 itself downloaded as 28.40 GB on Steam, 27.18 GB on Epic and 35.80 GB on the Microsoft Store, again varying by language. Open the sources below once more before you install.

Pre-install checklist

• Find your store's row: Steam 180.90 GB, Epic Games Store 180.65 GB, Microsoft Store 181.76 GB
• Confirm the target drive has more free space than that figure
• If you pre-load an update, remember Steam may need up to 353.00 GB and Epic 352.56 GB temporarily (Microsoft Store stays at 181.76 GB)
• Confirm you run Windows 10 64-bit, since support for Windows 7, 8 and 8.1 ended on June 4, 2024
• Confirm at least 6 GB of RAM (8 GB recommended) and a graphics card at or above the minimum list
• On a laptop, remember Bungie does not officially support laptop configurations and only says one that meets the minimum may be able to run it

If you record while you play

DOR has supported Destiny 2 since October 2026 and records the full match automatically, saving it as an mp4. For this game it does full-match recording only, with no automatic highlight clips. On an NVIDIA graphics card, NVENC hardware encoding is the default, and DOR captures game sound and your microphone together, so your own callouts can stay on a raid recording. If recordings land on the same drive as the 180.90 GB install, they share its free space, so how to reduce game recording file size is worth a read. DOR's own specs and file-size numbers are not published, so none are given here. Bungie's third-party compatibility article lists specific named apps and does not mention DOR, so read its recording app guidance in the sources below before you start recording.

Official sources (checked October 6, 2026)

Per-store install sizes and the pre-load figures come from Bungie Help: Destiny Platform Storage Requirements. The store's system requirements and the 105 GB note are on the Steam store page, and capture-app guidance is in Bungie Help: PC and Third-Party Application Feature Compatibility. Bungie's PC requirements article and Steam list the same minimum and recommended hardware, and the dxdiag steps follow Microsoft's support article called Open and run DxDiag.exe. Storage numbers can change with a major update.
