SkiaCustomMultiThreadedBase

A High-Performance, Multi-Threaded Rendering Skeleton for FMX & Skia4Delphi Experimental v0.3 alpha

This is a minimal, abstracted rendering engine designed to solve the Main-Thread Bottleneck in FireMonkey (FMX) applications.
It moves all heavy rendering logic (drawing images, effects, particles) to a background thread pool, while the main UI thread simply displays the finished image.

⚡ Key Features

Multi-Threaded Architecture: Spawns configurable worker threads.    
Double Buffering: Renders to an off-screen surface to prevent flickering/tearing.    
Strip Rendering: Divides the screen into horizontal strips to parallelize workload.    
Non-Blocking UI: The main thread remains responsive even under heavy load.

⚠️ Experimental Status

This unit is experimental. Just an idea i got while implementing doublebuffering and thought of how miniled split screen in regions...

Multithreaded rendering works and looks ok now, no flicker, real and target fps get same at 120Hz, 144Hz not anymore - around 128fps then, 256 threads only get 20fps here at ryzen 7 5800x

we running stable now so far, no big memleak anymore, but a little...

oh and yes ...sure tried it...256 threads on Asus zenbook ux305ca dual-core Intel m3 lol
he survived luckily and done 13fps still oO impressive compared to the ryzen...
