FAQ

Not really frequently asked questions, more just questions that have a simple answer.

Which version of ArcViewer should I use?

This is detailed in a dedicated page.

[Web Version] ArcViewer doesn't load and the browser shows an error "Runtime Error: memory access out of bounds."

This can happen when ArcViewer updates, and is likely an issue with browser caching. A hard refresh (ctrl+F5 in most browsers) appears to consistently fix the issue.

My framerate is really bad!

While ArcViewer is a pretty small web app, it's still a 3D application and isn't dirt cheap to run. I'm always doing work to optimize it as much as I can, but many old computers and mobile devices will struggle to run it at a good framerate.

However, there are some settings you can change to get the highest framerate possible:

  • Render scale under the "graphics" tab reduces the resolution of the app and will usually improve framerates massively
  • Bloom also under graphics settings - reducing this to 0 will disable bloom, and save on graphics performance
  • Static lights under the "visuals" tab disables the lightshow entirely, and saves a bunch on processing power
  • Light glow under visuals - just like bloom, setting this to 0 will disable the light glow and save on graphics processing

How can I load maps?

Maps can be loaded from a number of sources:

  • pasting a map key from BeatSaver (the numbers and letters next to the "key" icon on a map card)
  • pasting a direct URL for a map on BeatSaver (for example, https://beatsaver.com/maps/ff9)
  • pasting a direct file link to a .zip file containing beatmap files (song, cover image, Info.dat, and the difficulties) for example, a Discord attachment
  • selecting a .zip file from your own files by clicking the "open explorer" button
  • if you're running the desktop version: you can also select any .dat file from an unzipped beatmap through the file explorer. When loading a map from your local files on the desktop version, zipped or unzipped, you can tap R or click the reload button to immediately update the preview to any changes

How can I report issues?

Reporting issues effectively is very important to getting them actually fixed. You can find more info on how to make a good issue report in the developing guide.
