Performance Tab
The Performance tab allows you to optimize the performance of the True-Sky addon by adjusting various settings
Volume Presets: Choose a volume preset that best suits your needs in terms of speed and quality.
- Fastest: Pure focus on speed.
- Fast: Most focus on speed.
- Balanced: Balance between speed and quality.
- High: Most focus on quality.
- Highest: Pure focus on quality.
Camera Render Region: This setting "blocks" any pixels outside of the camera's view from being rendered. Enabling this option limits the amount of rendering needed and speeds up viewport performance.
Viewport Render Region: Enable this option to limit what part of the scene is being rendered in the viewport. This is useful if you only want to preview a specific area. Enabling this option reduces the amount of work needed to render the viewport and improves performance. You can manually draw the viewport render region by pressing CTRL+B or CMD+B while hovering your mouse in the viewport.
Pixel Size: Decrease the amount of pixels rendered in your viewport by binning pixels into bigger chunks. This improves performance, especially if you have high-resolution monitors or a low-end compute device. Recommended settings:
2x to 4x at 1440p
4x to 8x at 4k or above
Tile Size: Change the size of the tile used in final renders. This is recommended if you're using a CPU to render or have a low-end GPU. Adjusting the tile size provides a visually more performant render and, in some cases, reduces the strain on your system, preventing it from hanging. Note that this may increase the amount of RAM used by a small percentage in some cases.
True-Speed: Enable this option to approximate diffuse indirect light with background-tinted ambient occlusion. This provides a fast alternative to full global illumination (GI) for interactive viewport rendering or final renders with reduced quality.
