NVIDIA GeForce Game Ready Driver 617.42 was released on October 6, 2026 as a WHQL driver for Windows 10 64-bit and Windows 11. Its biggest gaming reasons to update are new Game Ready support for several current releases and a documented fix for an Assassin’s Creed Shadows crash introduced after driver 616.56.
The release is not automatically urgent for every GeForce owner. NVIDIA lists only one fixed gaming bug on the public driver page, and its official feedback thread still carries one confirmed open issue involving the “Prefer Maximum Performance” power-management setting.
There is also an important Windows 10 detail: 617.42 supports Windows 10, but NVIDIA has not identified it as the final Windows 10 Game Ready Driver. NVIDIA’s support plan still says the final Windows 10 Game Ready release will arrive sometime in October 2026.

Which games get Game Ready support in 617.42?
NVIDIA lists Game Ready support or optimizations for these current games and updates:
- Call of Duty: Modern Warfare 4
- STAR WARS: Galactic Racer
- Dragon’s Dogma 2: Dark Arisen
- Microsoft Flight Simulator 2024 Sim Update 7
- Valor Mortis
For players about to use one of those releases on a supported GeForce GPU, that is the clearest reason to move to 617.42.
“Game Ready” does not mean every listed game will gain the same performance uplift on every GPU. NVIDIA’s wording covers optimizations and support for the latest game and DLSS/RTX updates. IGZ is not assigning an FPS gain where NVIDIA has not published one.
What does 617.42 fix?
NVIDIA lists one fixed gaming bug on the public Game Ready driver page:
Assassin’s Creed Shadows may crash to desktop after extended gameplay after updating to driver 616.56.
If you encountered that exact regression on 616.56 or a later affected branch, the documented fix gives 617.42 a concrete troubleshooting value beyond new-game support.
NVIDIA lists no fixed general bugs on the public 617.42 Game Ready page.
What known issue remains?
NVIDIA’s official 617.42 feedback thread lists one confirmed open issue:
“Prefer Maximum Performance” Power Management Mode may not be applied correctly.
That is the only issue IGZ is treating as confirmed from NVIDIA’s release communication in this article.
Users are also posting other problems in NVIDIA’s feedback thread, but an individual forum report is not the same thing as a confirmed driver defect. IGZ is not turning unverified user reports into a general warning about 617.42.
Game Ready 617.42 vs Studio 617.42
NVIDIA released both a Game Ready Driver and a Studio Driver at version 617.42 on October 6, 2026. They share the same version number, but NVIDIA publishes them for different priorities.
Game Ready 617.42 is the better fit for readers focused on current game launches and game-specific support. Its public Game Ready notes emphasize Modern Warfare 4, STAR WARS: Galactic Racer, Dragon’s Dogma 2: Dark Arisen, Microsoft Flight Simulator 2024 Sim Update 7 and Valor Mortis, plus the Assassin’s Creed Shadows crash fix.
Studio Driver 617.42 is aimed at creator workflows. NVIDIA’s Studio page highlights support for DaVinci Resolve 21.1, Adobe Premiere Pro, Perplexity App and Topaz Labs Hyperion 2.5.
NVIDIA’s Studio 617.42 page also lists several additional fixes:
- Judgment, Lost Judgment and Virtua Fighter 5 R.E.V.O. may fail to launch after updating to 616.56
- Samsung Odyssey G95NC may show no picture over HDMI after updating to the R615 driver branch
- some DisplayPort monitors may fail to wake after updating to the R615 driver branch
- the same Assassin’s Creed Shadows crash fix listed on the Game Ready page
Those additional items are listed on NVIDIA’s Studio Driver 617.42 page. IGZ is not treating them as newly confirmed Game Ready release-note fixes unless NVIDIA also publishes them on the Game Ready side.
For a gaming-first PC, Game Ready 617.42 remains the natural choice. For a creator workstation where application certification and creator-app stability matter more than day-one game profiles, Studio 617.42 is the more relevant branch.
Should Modern Warfare 4 players install 617.42?
If you are preparing to play Modern Warfare 4 on a supported GeForce GPU, 617.42 is NVIDIA’s current Game Ready release for the game.
That makes updating a reasonable default for an MW4-focused system, especially if you want NVIDIA’s current driver-side support for the game’s DLSS and RTX feature set.
This does not replace the game’s own hardware requirements or guarantee a particular frame rate. For the PC-side launch requirements, see IGZ’s Modern Warfare 4 PC requirements guide.
Should Assassin’s Creed Shadows players install it?
If you were affected by the documented crash after moving to driver 616.56, 617.42 is directly relevant because NVIDIA lists that crash as fixed.
If Shadows is already stable on your current older driver and you do not need support for the other newly covered games, the release notes alone do not create the same urgency. Updating is still NVIDIA’s general recommendation, but the specific gaming fix is targeted rather than broad.
Should everyone else update immediately?
Not necessarily for a gaming-specific reason.
For a stable PC that does not run the newly supported games and has not hit the Assassin’s Creed Shadows crash, the public 617.42 Game Ready notes provide a narrower benefit case than some larger driver releases.
That does not make the driver bad or unsafe. It means the decision should be based on whether you need what this release actually changes.
If you do update, NVIDIA provides 617.42 through the NVIDIA App and GeForce driver download pages.
Is 617.42 the last Windows 10 Game Ready driver?
NVIDIA has not confirmed that.
Driver 617.42 currently supports Windows 10 64-bit, and NVIDIA’s separate Windows 10 support plan says:
- the final Game Ready Driver supporting Windows 10 is planned for October 2026
- the first Game Ready Driver without Windows 10 support is planned for November 2026
- Windows 10 then moves to quarterly critical-security driver updates through October 2029
Because NVIDIA has not named 617.42 as the final release, it would be premature to call it the last Windows 10 Game Ready driver.
IGZ is tracking that transition separately in our Windows 10 Game Ready support guide.
What about GTX 10, GTX 900 and other older GeForce cards?
Windows 10 support and GPU architecture support are separate limits.
NVIDIA already moved Maxwell, Pascal and Volta GeForce architectures to a critical-security-only track beginning in October 2025. Moving those GPUs to Windows 11 does not restore normal Game Ready support.
Driver 617.42’s current supported-product list is therefore not a reason to assume every older GeForce family receives the same normal Game Ready feature path.
Who should install NVIDIA 617.42?
Strongest reasons to update:
- you are playing or preparing for Modern Warfare 4
- you need current Game Ready support for STAR WARS: Galactic Racer
- you need current support for Dragon’s Dogma 2: Dark Arisen
- you are using Microsoft Flight Simulator 2024 Sim Update 7
- you are playing Valor Mortis
- you were affected by the documented Assassin’s Creed Shadows crash after driver 616.56
Reasons to be more deliberate:
- your current driver is stable and you do not use any of the newly supported games
- you rely heavily on the “Prefer Maximum Performance” setting and want NVIDIA’s confirmed open issue resolved first
- you are on Windows 10 and are specifically waiting to identify the final supported Game Ready release
Bottom line
NVIDIA 617.42 is a targeted Game Ready release with clear value for several major current games and for Assassin’s Creed Shadows players affected by the 616.56 crash regression.
It is also still a Windows 10-compatible Game Ready driver, but it is not yet confirmed as the final Windows 10 release.
If you need one of the new game profiles or the documented Shadows fix, 617.42 has a strong reason to install. If your current system is stable and none of those changes matter to you, the public notes do not show a broad gaming fix that makes the update equally urgent for every user.
