+Garbage collection is still unfit for demanding games:
+1. GC requires ~2x the memory footprint to achieve equivalent performance to an game using manual memory management.
+2. GC consumes extra threads and memory bandwidth that could've been used for the game.
+3. ZGC trades off throughput for latency. In layman's terms, your game will run slower, but at least you won't have lag spikes.
+

+
+Correction: ZGC reduces the chance of hitching. It does not fully eliminate hitching.
