Tested with only FalseTweaks (3.9.0), FalsePatternLib (1.5.9), UniMixins (all-0.1.19), Optifine (U_E7)

Try adding Neodymium Unofficial to the pack

Already did and nothing changed

Make sure you're not running out of VRAM

[iocmet]

I don't

Just wanted to add that I also experience this (with neodymium installed as well) exactly as @iocmet posted in the above video. Terrain looks very glitchy on turning and fps is severely reduced

with Neodymium installed, open falsetweaks.cfg and set experimentalNeodymiumThreading to true. This is slightly less compatible with some modded blocks, but it should fix the stuttering at extremely high render distances. Make sure you read the comment above the config option.

The terrain flicker is normal if you're running at very high render distances, that's the multithreaded camera check. Low framerates make it more obvious, you can either enable the experimental threading option with neodymium to fix it, or set your render distance to something lower.

[MrFuzzihead]

Have tested with threaded chunk updates enabled and also enabling experimentalNeodymiumThreading to no avail. FPS was still severely limited. With threaded chunk updates disabled and experimentalNeodymiumThreading enabled FPS was as usual, high

We're currently working on rewriting the renderer, it will be fixed in the next major update.
