Performance & Scaling

Resolution Scale

The Resolution Scale determines the scaling factor for overlay resolution. The default value is 1.0.

Increasing this value scales both width and height proportionally. Since pixel count increases quadratically, higher values will significantly increase VRAM usage.

Scaling Examples:

Scale Factor	Overlay Size (Original: 512x512)	VRAM Usage Increase
1.0	512x512	1x (default)
2.0	1024x1024	4x VRAM usage
3.0	1536x1536	9x VRAM usage

Usage Considerations

This feature is mainly beneficial for Varjo headset users, as Varjo performs poor-quality scaling when compositing overlays. On other headsets, increasing Resolution Scale may improve text clarity and sharp edges, but it is not generally recommended due to the excessive VRAM usage.

OpenXR / Use World Locked Positions

This property is true by default. Setting it to false acts as a workaround for Varjo Base v4.4 and above, which have a bug causing world-locked overlays to appear in the wrong position or not at all.

When set to false, the OpenXR API layer will convert world-relative positions to head-relative positions every frame, submitting overlays as head-locked overlays instead.

Pros & Cons:

✅ Fixes rendering issues in Varjo Base v4.4+

❌ May cause overlays to feel 'floating' or 'jittery', especially at low frame rates

Users often describe this effect as overlays no longer feeling firmly attached to the world.
