A driver update can fix a game issue, add support or change performance. It can also introduce a problem on a particular PC. Update with a reason and keep enough information to reverse the change.
Identify exact hardware
Check GPU and motherboard or laptop model in Windows and the manufacturer's documentation. For graphics, use NVIDIA's official app, AMD support or Intel Driver & Support Assistant where applicable. For a laptop or prebuilt, check its maker's support page for model-specific packages, especially chipset and firmware.
Change one layer at a time
Note the existing driver version and your game's symptoms. Read release notes for relevant fixes or known issues. Close games, install the appropriate package and restart if requested. Test the same game scene and settings. Avoid changing driver, BIOS, game graphics and overclock settings in a single session because you will not know what caused the result.
If performance gets worse
Check whether the game or Windows updated at the same time. Restore the prior stable driver using the manufacturer's installer or Windows device rollback when available. Do not use unofficial driver download sites or automatic tools that cannot identify the exact device. If firmware is involved, follow our BIOS checklist before proceeding.
