NVIDIA describes the driver as providing the Game Ready experience for these titles and updates that use current DLSS and RTX technologies. That does not mean every feature is available on every GeForce GPU generation; technologies such as frame generation and newer ray-tracing features depend on the hardware and the individual game’s implementation.
Assassin’s Creed Shadows crash fix
The clearest bug fix in the 617.42 notes targets Assassin’s Creed Shadows. NVIDIA says the game could crash to desktop after extended gameplay after updating to driver 616.56. The issue is tracked as bug 6685219.
If that specific crash was your reason for avoiding the 616 branch, 617.42 is the first release in this sequence explicitly reported to close it. As always, a fix for one identified crash does not guarantee that every unrelated crash has the same cause.
Known “Prefer Maximum Performance” issue
Current release-note reporting continues to flag a problem where the NVIDIA Control Panel’s Prefer Maximum Performance power-management mode may not apply correctly. Reporting associates the issue with bug ID 6007998 and notes that it can be particularly relevant to laptop power behavior.
If you depend on that setting for a specific game or workstation workflow, verify clocks and behavior after updating rather than assuming the mode has taken effect. Avoid changing several driver and power settings at once, because that makes troubleshooting much harder.
Should you install 617.42?
The strongest reasons to update are straightforward:
- You are playing one of the newly supported games.
- You were affected by the documented Assassin’s Creed Shadows crash.
- You want the current WHQL branch before a new release.
If your system is stable on an older driver and you do not play any of the targeted titles, there is less urgency. A Game Ready release can be valuable even without a giant list of fixes, but stable systems do not need to chase every driver on launch day.
How to install NVIDIA 617.42
- Open the NVIDIA App and check the Drivers section, or use NVIDIA’s official driver download page.
- Confirm that the package matches your GPU and Windows version.
- Close active games and GPU-heavy applications before installation.
- Use the normal express installation unless you have a specific reason to perform a custom installation.
- Restart if requested, then verify the installed version in the NVIDIA App or NVIDIA Control Panel.
Do not download display drivers from random mirrors when NVIDIA’s own download is available. The official source reduces the risk of receiving a modified or outdated installer.
What if 617.42 causes problems?
If you see a new problem immediately after installing the driver, first identify whether it occurs in one game or across the whole system. A game-specific problem may be related to shaders, game files or settings rather than the driver itself.
For a reproducible driver regression, you can use Windows’ driver rollback path or install a known-good older NVIDIA driver. Save your current settings before making major changes, and avoid using third-party “cleaner” tools unless normal NVIDIA/Windows recovery steps fail and you understand what the tool removes.
617.42 and Star Wars: Galactic Racer
NVIDIA specifically names STAR WARS: Galactic Racer in the Game Ready list. AVARIXO has a separate Galactic Racer launch guide covering the game’s price, editions, PC requirements and modes.
