Why is Terraria not using GPU?

Here are the best solutions to apply when the Terraria not using GPU problem occurs.

- Double-click on the Display Adapters section.
- Right-click on your GPU and select the Update driver option.

2. Launch Terraria in native resolution
Games perform the best when played in the native resolution of your display. Since some players had issues changing this setting, we decided to drop the easiest and most effective way to launch and play Terraria in the native resolution.
- Launch Steam.
- Right-click on Terraria and select Properties.
- Scroll down to the Launch Options in the default General tab.
- Paste -w 1920 -h 1080 (for 1920×1080 resolution) and close Properties.

- Use the CTRL + A shortcut to select all files in the folder.
