#12 Re: General » Development builds » 2023-07-25 00:48:27

Build 20230724-dev

This is a very significant performance update. I've been working on it over the past few months. Some of the core parts of the engine were rewritten - partially or completely - with performance in mind. I've changed significantly many things behind the scenes and I was able to make the engine a lot faster. There has never been a performance update as radical as this one!

Download: https://download.tuxfamily.org/opensurg … 24-dev.zip

Highlights:

  • Breaking change: the definition of what an entity is has been changed! Previously, objects tagged "entity" were considered to be entities. Now there is an added requirement. Please read it on the docs.

    • Most existing entities already abide by the new definition. A few former entities do not. The engine will attempt to find such cases and warn you about them. If you get a warning, fix it as instructed.

  • Rewritten the entity management system. Made it faster with space partitioning based on my quadtree variant designed for the SurgeScript object tree.

  • Rewritten the brick management system. Made it faster with space partitioning based on a spatial hash with faster iterators.

    • Re-implemented the level height sampler

  • Optimized the rendering system / batching system

    • Press F10 during gameplay to see the batching stats (less batches means less draw calls and increased performance)

    • Introduced an experimental "low quality graphics mode", available at the options screen, based on a Z-buffer and with more aggressive batching

    • Experiment with a pair of FBOs used in a round-robin fashion in an attempt to prevent possible pipeline stalling in some drivers

  • Optimized collision detection. Made it a lot faster with mathemagics and with a quick partitioning scheme!

  • Optimized loading times

  • Optimized the scripting engine:

    • Optimized program lookups / function calls with self-modifying SurgeScript bytecode that recognizes opportunities for optimization

    • Optimized tag tests with faster hashes and bitsets

    • Introduced managed strings: optimized the allocation and the deallocation of strings with a pool

    • Made other changes related to temporary objects and to garbage collection

  • Optimized the rendering of fonts

  • Re-implemented the rendering of backgrounds with faster batching

    • The Waterworks 2 background is now based on a single image file for optimal batching

    • The baddies of Waterworks Zone are also on a single image file

  • Rewritten the animation system. Optimized the lookup of transitions.

  • Lots of refactoring and improvements to the internal parts of the engine

  • Scripting: updated the Profiler object

  • Scripting: added Level.findEntity(), Level.findEntities(), Player.moveBy(), Player.move(). Changed EntityEvent.

  • Introduced warnings about the future removal of the legacy scripting system / legacy items (0.2.0)

  • Removed the legacy particle system. Re-implemented particles as SurgeScript entities

  • Tweaks to the physics system, to some levels and to some scripts

  • Made changes to the Debug Mode

  • Bugfixes and other changes
