Whole modpack: world generation
1.0.26 ON TOP of ModernFix, FerriteCore, Radium and C2ME: 512 chunks 567 -> 102 s (5.6x); spawn prep 277 -> 58 s (4.8x); allocation/chunk -87%. Four runs per arm. Server live heap +70 MB. Client also keeps Embeddium and ImmediatelyFast.
Whole modpack: the same scene
Historical 1.0.21 test (30 Sep): ON TOP of the existing client performance stack, 64 mobs +10% average FPS / +16% 1% lows; GPU-bound overlook +29% 1% lows, average unchanged. Four runs each, shaders on. Not a new 1.0.26 FPS measurement.
Six measured hot spots
Six measured hot spots, upstream vs Bons and Furious 1.0.26. Each panel is its own measurement in its own fixture and unit; results are not additive and do not establish a combined FPS or TPS gain.
Terrain generation
New vanilla terrain controls (1.0.16, 1.0.18): NoiseChunk construction 10.35 → 0.89 ms CPU, structure height query 17.7 → 8.3 ms, and 95.3 % of ground-height scans served from a shared table; a 144-chunk run in about half the wall time. Not a TPS figure.
Frame pacing
Frame pacing at the same 120 FPS cap: p95 frame-to-frame jitter, p99 swap interval and frames over 16.67 ms in two scenes. Achieved FPS unchanged; buffer-swap intervals measured inside the JVM, not on screen.
World-generation fixes
Seven generation-context fixes for Distant Horizons and C2ME worker threads, with the reproduced Scuba Gear stall: 6.057 → 20 TPS. One reproduction per fix; not a whole-pack result.
Client paths
Client-side paths: the share of each measured cost remaining with the patch on (Oculus 1.8.0, Embeddium 0.3.31, ImmediatelyFast 1.5.5, ETF 7.1, Forge 47.4.16, DH 3.3.2, EntityCulling 1.10.5, AmbientSounds 6.3.8). Not frame time, not additive.
Server paths
Server-side world, ship and data-pack paths: the share of each cost remaining with the patch on. Full-pack world A/B, Valkyrien Skies sweep fixtures (each row one sweep against the build before it), and two rows measured in game for 1.0.23.
Libraries, mobs, animation
Shared libraries and mob/animation paths on both sides: the share of each measured cost remaining with the patch on. GeckoLib, Architectury, Curios, Goblins Tyranny, Under the Moon, Nether Depths Upgrade, Ars Nouveau, Spawn, TaCZ, Cryptic Foes.
Allocation per call
Bytes allocated per call, upstream vs patched, for the allocation-focused controls, plus terrain preparation (1.474 GB → 0.595 GB over 64 height queries). Thread allocation counters in the native fixtures.
248 controls by area
What is inside 1.0.30: 248 switchable controls by area and kind (215 optimizations, 4 deliberate changes, 29 fixes), vanilla plus Forge and 79 optional mod targets, every one with its own switch.
