I've been focus this past two months on improving the performance, in some screens mixing many elements, enemies, particles, lasers, liquids and moving backgrounds was affecting the performance, so I did what I love, to dig into the code and start measuring and comparing, I'm quite happy with the results, now I can throw many particles here and there that performance is not affected.
I did focus on DirectX buffers: hash created only when needed, buffers only sorted when needed, tailor-made drawing triangle functions, RGB to int conversions.
Surfaces are now generated faster when they are in 32 bits.
Also the new TFastPool<T> used in particles it excels, and indexed array for fast access with a pool mechanism in the same structure (maybe I will explained in another post)
What's new:
BB)
Clear camera also clear perturbation values
New StartSize/EndSize particle properties, autoSize particle removed
Camera constructor does not longer sets the size in the constructor
All primitives now use InView() to check whether this primitive has to be rendered or not
Line with thickness is now done properly with perpendicular vectors
Now GlowLine() uses a line with thickness
Now particles have X and Y radius
Fixed some Z issues in primitives Line() and Triangle()
New TScreen.WaitBehaviour, buffers can be only resorted when creating new buffers
General improvement in the hash keys of the maps
New TLayer.FindProperty()
Glow rendering improved
Particles now can have a trail

New TParticleEmitter Sleep and SleepEvery properties
Now Particles uses TFastPool<TParticle2D>
Particles can be glowed
Alpha32 surface detection improved
Particles generated in Sphere fixed
All internal sin/cos calculations in particles are done in RAD so no conversion needed (extra multiplications)
Particle generator loop improved
Render buffer improved
Color performance in buffer improved for surfaces
Queue<T> improved
TPolygon.GetHash() improved
TScreen.FillSurface() improved
Surface cache improved
Sprites now maintain the hash of the buffers
Surface.AndMask() performance improved
Buffer hash generation had collisions (bad key)
Now particles work by time and not steps
Now TObjectEx implements IGroup
Added friction to particles
Some critical functions checks are executed only in debug mode
Particles now do some kind of occlusion via BB
New particles spread mode Expand
Now particles can take the form of shapes
Now Particles can have up to 8 different textures by default
An emitter can be inactive
HBF)
Cables throws more sparks
Camera size is update when resolution is changed

New Path helper to create entities following map attributes
New enemy Rotator
Shover is shown properly when gravity is up
New Achievement "burn the block!"
Hero input code moved to Hero class
Added moving tapes to some levels
New element Wheel (HL2?)
Now all entities might target a tile (by name) and do something
Lava melting ice code fixed
Now demos can also track input from attack and action
New item Wand
