- Fix random low res mip levels by using NativeParallelMultiHashMap instead of FixedList to avoid running out of space.
- Fix dropping off-screen instances to low res mip levels by considering all instances for mip level calculations instead of just culling surviors. The old off-screen behavior can be examined by setting `indirect_instancing.streaming_use_all_instances 0`.
- Mitigate dropping Unity renderers to low res mip levels when Unity's and Indirect Instancing streaming systems disagree by calling ClearRequestedMipmapLevel() when we have determined mip 7.
Fix floating point overlow in mip level calculation
- Clean up texture streaming jobs
- Fix wrong camera position in Streaming_FallbackSquaredDistanceJob
- Add various debugging ConVars
- Add "Indirect Instancing" UI Indicator
Experimental frame synchronisation ConVars
Fix monster mesh rendering issue
Reset some CodeGen to their state on /main
- Create buffers with correct flags according to `buffer_upload_mode`
- Set default buffer upload mode to be "indirect" (1)
- Disallow changing `buffer_upload_mode` during gameplay
un-gate indirect instancing for testing purposes
Fix build by scrapping the function pointer idea.
- Fix rendering issues due to various jobs executing for command indices that are no longer in use.
- Fix broken debug draw when damage region bitscan job is active.
- Split `surviving_command_counts` into `command_counts_after_culling` and `command_counts_after_reordering` for clarity.
- Create a universal IsCallVisible() function instead of the mess we had before
- Rewrite the buffer update logic to ensure a direct update only happens once per frame to make DX11 happy.
- Always update the entire buffer to make greedy GPU drivers happy.
- Add IGraphicsBuffer wrapper because Unity didn't do it so I can finally stop copy/pasting everything.
- Use a function pointer (👻) in damage region processing for similar reasions.
- Unlock the arrays in Update in case OnPreCull wasn't called.
- New debugging ConVars: `reorder_instances_job`, `damage_bitscan_job` and `buffer_upload_mode`
A whole marathon of Indirect Instancing changes:
- Schedule all jobs at the beginning of LateUpdate() for better worker utilisation.
- Further improve scheduling behavior by modeling actual dependencies between jobs using writes_to_* and reads_from_* handles.
- Allow instance reordering and command aggregation to run in paralell to give even more flexibility to the scheduler.
- Run the debug overlay (where possible) in parallel with the jobs to improve performance
- Avoid garbage allocation when scheduling the frustum culling job. (GeometryUtility.CalculateFrustumPlanes)
- Schedule all jobs using ScheduleByRef.
- Correctly set `[ReadOnly]` and `readonly` for all jobs to help Burst as much as possible.
- Make batch size tunable: `indirect_instancing.batches_per_worker`
- Add somewhat automatic instrumentation to CrudeProfiler via `using` statements.
- Add ProfilerMarker to mimic what Unity 6 is doing with `using` statements. (Still need to verify it this compiles out properly.)
- Add more profiler instrumentation.
- Rename a ton of things for clarity.
- Remove CommandBuffer. We won't need it where we're going.

Regenerate ConVars and force bounds to be always huge (experiment)
Add a third submission mode to indirect instancing which works through `Graphics.DrawMeshInstancedIndirect` and avoids copying to a command buffer.
Enable `indirect_instancing.command_buffer` to switch back to the old way.
Finalise SIMD terrain culling implementation:
- Fix oscillation/flicker bug by tracking individual ray progress properly.
- Adjust step size dynamically with altitude to reduce iterations.
- Limit overall iterations to ConVar `indirect_instancing.tc_max_iterations`.
- Ignore rays to instances that have been culled in a previous step.
