Any ways to further reduce FPS drops and stutters when using DH and C2ME?
When using C2ME with or without DH, chunk generation inside vanilla render distance is significantly accelerated, but using both mods causes massive FPS drops and stutters while generating chunks. This is less noticable with fewer mods, but gets worse with each additional mod (for example FPS drops to 10fps with ~150 mods while walking - not sprinting and 5fps during initial generation on view distance 12).
For the sake of this post I have tested the generation time and fps during generation in various configurations. I am testing this on these high settings to really stress the limits so once I add more mods and use a more reasonable view distance those issues hopefully don't exist at all.
DH 2.3.0-b
C2ME 0.3.0+alpha.0.60
Java Args (these slightly reduced the issues):
View Distance: 32
Simulation Distance: 32
LOD Distance: 256
Quality Preset: Whatever is default because DH keeps changing it to custom despite no changes
CPU Load: Balanced
Bliss Shaders (github) without changes
Not looking around during initial generation only flying up to y150
Setting the CPU Load to Minimal completely removes the FPS drops during initial generation (while not moving) but still causes light stutters and FPS Drops to 40 (instead of 15-20) while moving
Results:
No DH & no C2ME: 2:11m - 130-110fps (gradual decrease with visible chunks)
C2ME only: 0:53m - 130-110fps (gradual decrease with visible chunks)
DH only: 2:43m - 130-110fps (gradual decrease with visible chunks)
DH & C2ME: 1:07m - 20-110fps (20fps during generation with jump to 110fps when no vanilla chunks are being generated)
With DH and C2ME CPU is pinned to 100% during initial generation and while moving no matter what CPU Load is set in DH
