What's new
New Features
- Hand light now has screen space ray traced shadows.
- A new Hand Light shader pack options screen has been added to control this feature.
Improvements
- Hand light is now handled separately for each hand.
- Hand light sources are now positioned more closely to actual hand positions.
- Significant improvements have been made that depend on the Subgroup Operations Compatibility option.
- Lights are now de-duplicated using subgroup operations before being added to the global light list, significantly reducing the capacity required to avoid overflow and the time spent on global de-duplication.
- Work group bounding box computations are now accelerated using subgroup operations.
- Atomically pushing to buffers is now accelerated using subgroup operations.
- SSBO and shared memory loads are now explicitly made subgroup uniform where possible, using subgroup operations.
- Volumetric light and SMAA neighborhood blending are now significantly faster thanks to optimizations made to work group neighborhood handling.
- Chunks are now culled in uniform control flow.
- Light list creation is now slightly faster when 16-bit integer types are unsupported.
- Sky rendering is now slightly faster, by skipping a work group barrier in tiles with no block lit geometry.
- Gbuffer data is now ordered more optimally following the RDNA Performance Guide.
Other Changes
- Amethyst Shards are now emissive.
- Ambient occlusion is now more visible. More improvements to ambient occlusion are planned.
- Hand light brightness now matches block light by default.
- Work group sizes have been retuned and optimized for modern AMD Radeon hardware. This could result in worse performance on some other hardware. Please report any significant issues.
- Subgroup operations are now assumed by default to be supported on all Radeon hardware.
- Immutable constants are now assumed by default to be supported on all Radeon hardware on Linux.
- A driver bug workaround for the work group size of the global light list de-duplication pass has been disabled on Mesa graphics drivers for Radeon. This could improve performance slightly in some situations.
Fixed Issues
- Light list sorting fails when multiple lights are at the exact same distance from the player.
- Unlit geometry is rendered with incorrect depth guarantees, causing undefined behavior.
- Fallback functions collide with disabled built-in 16-bit functions on AMD graphics drivers on Windows (driver bug).
