FAQ

Does the driver advice apply indefinitely?
No. It records the developer’s October 28 launch advisory and should be checked against later updates.
Can I compare pre-load performance without updating?
If your launcher offers the launch update, install it before benchmarking; the described patch includes tracing-performance work and bug fixes.

Phantom Blade Zero (PBZ)

What should you check before changing graphics settings?

Check whether your launcher offers the launch update and let any offered update finish and record the build you are testing. Use the same location and camera position for comparisons where possible. Changing both a driver and several graphics settings together makes it hard to identify what helped, so begin with a clear baseline and change one variable at a time.

Should you always install NVIDIA 617.42?

No permanent recommendation follows from a pre-release advisory. The developer’s October 28 message preferred that version after observing problems with 621.01, while expecting another update. If your system is stable, check newer official guidance before a rollback. This is specifically NVIDIA guidance; it does not identify a recommended AMD driver.

What is a useful troubleshooting record?

Write down the game build, driver version, resolution, upscaling choice and whether ray tracing is enabled. Repeat a short route after one adjustment, then compare stability and image quality as well as frame rate. This produces information you can use in a support report without inventing a universal best preset.
