Описание
This mod does a low-hanging-fruit optimization for Create factory gauge rendering.
## Why It was Slow
Factory Gauge is a block entity, and the base mod renderer does vertex transform for gauge paths every frame. this has very high overhead considering the path is mostly unchanged across frames. Existing approaches such as createbetterfps, Flerovium does not change this immediate mode model; This mod utilizes flywheel to provide instancing support.
## Limitations
Item may have custom renderer. those item will fallback to slow path.
This mod is client only. it doesn't optimize server ticks.
This mod is ad-hoc, low-hanging fruit optimization for create factory gauge rendering. it doesn't provide a full solution to making your fps better.
This mod optimizes CPU frame time more than GPU frame time. if shader used, improvement may be small.
## Evaluation
Evaluated in controlled scenario: superflat world, with a 10x30 wall, each block has 4 gauges. significant improvement in sparkc profiler. result in figure.
Evaluated in realworld scenario: referencial 80h+ survival world, same spot standing still. VSync off, max frame no limit, sodium: CPU render ahead 1 frame, photon shader ultra preset.after warm up, PresentMon shows (10s interval)
