Capture problems in Alt1

This page contains information about common problems with Alt1 capture and how to fix them. You can change the capture settings by going to capture tab of the Atl1 settings.

Setting the right capture mode

The capture settings.

Alt1 has three capture modes, OpenGL or DirectX are preferred and Desktop can be used as fallback. Alt1 will try to detect the correct capture mode but might make the wrong choice.

You can select different radio boxes to make the preview box show the game client.


  • This mode should work for the NXT client for every computer.
  • In the past some antiviruses have deleted files related to opengl capture. Make sure that you antivirus does not delete files without telling you about it.


  • This mode usually doesn't work for the NXT client. It depends on your graphics card and drivers if this works.
  • It might show a static image with some parts of the game in the preview box. This doesn't mean it works or is partially working.


  • This mode is a backup and shouldn't be used if the other modes are available.
  • It work if you use display scaling with high DPI monitors in Windows 8.1+
  • It wont work if other windows or overlays are covering the rs client.
  • It is much slower than the other modes.

Scaling mode

Since Windows 8.1 some programs can be stretched out by Windows in order to make them larger on high DPI screens. Alt1 normally automatically detects this, but certain combinations of settings might make Alt1 make the wrong choice. You can override this click checking the "override DPI scaling detection" checkbox. Toggle this checkbox in such a way that the preview box shows the full game with no extra space around it.

Other problems

If all other settings seem correct and Alt1 still can't find the home teleport button there might be a different problem.

Overridden driver settings

If you have a Nvidia graphics card some graphics settings might be overridden in your driver. One of these settings breaks Alt1 as it blurs out your complete game.
