Mobile Gameplay Performance Optimization

MOKSHA — v0.1.1 Devlog

Date: 2026-08-18
Milestone: v0.1.1 — https://github.com/weirdcodesofficial/MOKSHA/milestone/11

Highlights

• Major mobile-focused performance work: reduced per-frame CPU/GPU cost in render path.
• Replaced hot trig math with a lookup table (LUT) to remove repeated Math.sin/cos calls.
• Cached per-frame gradients and reduced expensive shadowBlur calls to lower GPU blur passes.
• Added quality-tier controls and explicit render-state resets for more predictable mobile behaviour.
• v0.1.1 release PR merged.

Merged pull requests (summary)

• PR #147 — perf(render): replace remaining Math.sin/cos with lutSin/lutCos
  
  Replaced ~25 per-frame trig calls in drawScene() with reads from the existing 2048-entry radian LUT (affects ring ticks, pulses, orbit waves, arc heads, timer pill pulses, etc.) — reduces CPU trig cost significantly.

• PR #145 — render: Done gradient caching.
  
  Implemented caching/baking for commonly created gradients and offscreen sprites (pickup glow, naama, chakravaata, rein gradient buckets) to avoid per-frame gradient allocations and GPU work.

• PR #144 — render: quality tier control, explicity reset, 40 shadowBlur calls wr…
  
  Added device/quality-tier checks to disable or lower shadowBlur on low-end devices; isolated shadowBlur via save()/restore() and explicit ctx.shadowBlur = 0 resets to avoid leaks. GPU blur pass count reduced.
