Alt1 Toolkit changelog

This log only contains changes that require an update to the installed Alt1 Toolkit. The individual apps are updated on a weekly basis and will load automatically the next time you open the app. Notable app updates are posted on the Discord server.

Alt1 1.6.0 Release1 Jan 2023
Improve Alt1 stability and fix OpenGL capture when NVIDIA filters are enabled. It also adds support for multiple release tracks to make future updates easier.

This change log only contains changes to files on your computer, Alt1 apps are updated separately and don't require an update to Alt1 itself.

Since this is a new update some antiviruses might give you a warning. Especially if you're using AVG/Avast, make sure it is not set to 'Automatic repair', this mode will delete files at random.


  • Added a setting to delay Alt1 updates until after antiviruses have updated.
    • Most antiviruses take 1-2 days to update their detections, however with AVG/Avast this can take up to 3 months. This option minimizes problems with these antiviruses deleting Alt1 files without telling you.
    • Enabled automatically when AVG or Avast is detected. (Your antivirus is making your computer less secure!)
    • In the future there might also be a beta track to test updates before release.
  • Finally tracked down a bug that would cause Alt1 to become partially unresponsive after waking your computer from sleep.
  • Added a work-around for the infamous NVIDIA image sharpening and softening filters. Alt1 will now accurately capture the game even if those settings are enabled.
  • Updated the built-in chromium browser to version 108.


  • Alt1 now always runs as 64bit application.
  • Alt1 now requires .NET framework 4.6 (up from 4.5.2). This should already be installed on windows 8/10/11.
  • Apps can no longer capture your screen outside of the RuneScape window.
    • This feature is currently only used by the Comp cape color grabber app.
  • Starting a second instance of Alt1 now gives you an option to kill the old instance in case it has frozen.
  • Added support for headless install (makes it technically possible to install through winget - not yet implemented)
  • There is now a button in settings->advanced to show the internal Alt1 console.
    • This console shows errors that happen inside Alt1 but don't result in a crash.
    • This is useful for debugging issues with appconfigs and alt1:// urls.
    • Also added and updated messages for many other issues.


  • Fixed several memory leaks.
  • Alt1 will no longer show an error about admin mode when the rs client freezes.
  • Alt1 will now automatically detect the RuneScape client in compatibility mode as well.
  • Fixed an issue interface skins not showing up in supported apps.
Alt1 1.5.6 Patch7 Sep 2020
This update fixes several long standing annoyances as well as a new bug introduced by the clue solver rework.

This change log only contains changes to files on your computer, there have been many other updates to the apps themselves in the last month which don't require an update to Alt1 itself.

Since this is a new update some antiviruses might give you a warning. Especially if you're using AVG/Avast, make sure it is not set to 'Automatic repair', this mode will delete files at random.


  • Added a warning when Alt1 is unable to function if RuneScape is running as admin.
  • Added a warning about capture when RS is minimized.
  • Made the incomplete reinstall warning harder to miss.
  • Updated the built-in chromium browser to the version 83.


  • Fixed some capture problems which were causing the clue solver to crash/freeze.
  • Fixed a memory leak with rightclick detection. You can now turn on rightclick detection again in the settings if you've previously turned it off.
  • Fixed a very rare bug that was causing the game to freeze on custom cursors until hard reboot.
  • Fixed the font size on text overlays under certain display scaling settings.
  • Fixed a freeze as computer wake after (dis)connecting a second monitor.
  • The stats app was some times opening on 'From [name]' instead of the name itself
  • Fixed some edge case problems with rightclick detection.
  • Fixed several other obscure crashes.
Alt1 1.5.5 Patch27 Aug 2019
This is mainly an update to fix right-click detection. Also includes a new browser version and some fixes.


  • Fixed right-click alt+1 hotkey detection.
  • Fixed right-click menus not overlapping alt1 windows. (way more problematic than it might seem)
  • Updated the built-in browser (chromium 75).
  • Fixed a technical issue with accelerated image detection. Apps were forced to build workarounds.
  • Fixed tooltips in apps. You will be able to see tooltips on teleports in the clue app again.
  • Apps now get more information about right-click menu contents.
  • Fixed a couple other small issues.
Alt1 1.5.3 Patch15 Apr 2019
Fixed a load of issues after the 1.5.1 threading rewrite. Also added two new apps.

New apps

  • Added an ability tracker app.
    • This app shows the expected damage for abilities that you use independent of rng or gear.
    • Shows a running average of your last 20 seconds expressed in 5 minute dummy score.
    • There is a special streamer mode to add this information on an overlay on twitch.
    • Make sure you have cooldown numbers enabled in the rs display settings.
  • Added a simple Angel of Death app.
    • Shows the kill order of the minions.
    • You can find this in the utility folder.

Main changes

  • Fixed Alt1 freezing when changing your desktop background (and other settings) after closing an rs client at least once.
  • Fixed alt+2 screen capture for people where it wasn't working.
  • Open apps on the toolbar are now fully independant of apps on a different client. This means that you no longer have to right-click to open the same app on multiple clients.
  • Added stupidly fast subimage search that utilizes specialized processor features (SSE/AVX). This will make existing apps faster and enable new features in apps that were previously too slow.

Other fixes

  • Fixed possible (rare) crash while closing rs.
  • Fixed the Alt1 icon not showing the correct number of linked clients.
  • A small version of the Alt1 toolbar will now show up in windowed fullscreen mode
  • Fixed apps scaling to the wrong resolution. (hopefully for everyone this time)
  • The app close button and other buttons weren't visible for some people.
  • Cleaned up more multiclient weirdness.
  • Pinned/recent app icons on the toolbar no longer get misaligned after clicking them.
  • FOUND THE OTHER STUPID FREEZE BUG. This one was happening since day one. Thx microsoft.
Alt1 1.5.2 Patch19 Mar 2019
Fixed a bug with DirectX capture in combination with display scaling.
