Bons DLSS Diet

Bons DLSS Diet

Same picture. A third more frames.

NVIDIA DLSS for Complementary Unbound shaders on Minecraft 1.20.1 Forge. Everything is in one jar.

Requires Oculus with Embeddium, Complementary Unbound r5.7.1 with Euphoria Patches 1.8.6, Windows and an NVIDIA RTX card. Client only. Free, MIT licensed.

New in 1.2.0

Less smearing on moving ships, mobs, hands and held weapons, plus adjustable RCAS sharpening. The night-sailing test showed a much clearer ship around lanterns. If distant textures shimmer, reduce sharpness or move mip_bias closer to 0. See the changelog for the test limitations.

A third more frames per second

At 4K with shaders on, the graphics card does almost all of the work per pixel. DLSS Quality draws the world at two thirds of the screen size, less than half the pixels, and builds the full frame from them with NVIDIA's AI model. On an RTX 3080 that was 35 to 44 percent more frames per second in the scenes we measured, with the same detail.

Measured with Bons DLSS Diet 1.1.0, not a new 1.2.0 benchmark. RTX 3080, 3840x2066, Complementary Unbound r5.7.1 + Euphoria Patches 1.8.6 with Distant Horizons, in a 550-mod pack. Same saved world and settings, measured the same night, 16 October 2026; medians of the per-second frame rate over three runs. Your numbers depend on your card, resolution and settings. DLSS pays off when the graphics card is the limit; a scene limited by the processor gains little.

Want more? DLSS Quality is the default because it looks like the native frame. Balanced, Performance and Ultra Performance draw fewer pixels for more frames; DLAA keeps the full resolution and uses DLSS for anti-aliasing only.

How it works

On the first start the mod writes a copy of the shader pack you already have, named <your pack> + DLSS, next to the original. Pick that copy in the shader menu. The original stays untouched and your shader settings carry over. The jar contains none of Complementary's code; it works like Euphoria Patches does.

With the copy selected, the shaders draw everything before the final passes at the render size, jittered, and supply depth for motion reconstruction. The runtime calculates camera and object motion for entities, ships, hands and held items. Bons DLSS Diet hands colour, depth and motion to NVIDIA DLSS through a small native library (Vulkan, sharing the frame with OpenGL on the graphics card, no copy through the processor) and puts the full-size result back where the shaders read it.

• Full-resolution textures. Roof tiles, leaves, water ripples and generated normals keep the detail of a native frame; the shaders pick the texture level for your real screen size.
• Everything else keeps working. Reflections, depth of field, volumetric light, clouds, Distant Horizons LODs, the End and the Nether.
• DLSS replaces the shader's TAA and FXAA. Moving mobs, turning Create gears and a sailing Valkyrien Skies deck stay crisp.
• Light. About 2 ms of graphics card time per frame for DLSS itself at 4K on an RTX 3080, and well under 1 ms of the game's render thread. It runs in the game's own OpenGL context: no second window, no restart dialog.
• Safe. No RTX card, an older driver, no 64-bit Windows: the pack simply runs without DLSS and the log says why. Check the log if DLSS stays off.

Gets along with your other mods

Hooks in Oculus supply shader settings, jitter and the upscaling step. Minecraft hooks request OpenGL 4.6 and capture hand and held-item poses during world rendering. Valkyrien Skies ship transforms are read when that mod is present.

We test it in a 550-mod pack, scene by scene, with DLSS on:

• Create cogs, fans and shafts turning (Flywheel instancing through Colorwheel) and Valkyrien Skies ships under sail.
• Distant Horizons LOD terrain to the horizon, Alex's Caves cave biomes, Cosmic Horizons space, the Nether and the End.
• Mobs, name tags, glowing and enchanted armour, the hand, signs and item frames, tinted-glass mirrors, portals, rain and night lights.
• Mid-game actions: window resize, shader reload, shaders off and on, resource reload, third person.
• Alongside Embeddium, Fancy World Animations, Entity Model and Texture Features, Fusion connected textures, Mekanism, Immersive Engineering, Alex's Mobs, Supplementaries and 500 more.

What you need

NVIDIA's DLSS library is included in the jar.

Install

1. Put bons_dlss_diet-1.2.0.jar in your mods folder with the mods above and start the game.
2. Options, Video Settings, Shader Packs: choose ComplementaryUnbound_r5.7.1 + EuphoriaPatches_1.8.6 + DLSS.
3. Play. DLSS is on. Restart the game once when convenient for the full frame rate (see below).

Client only. Nothing is needed on a server.

Settings

config/bons_dlss_diet.properties, read whenever the shader pack loads (shader menu or the reload key):

• mode: quality (render at 67 %, the default), balanced (58 %), performance (50 %), ultra_performance (33 %), dlaa or off.
• preset: the DLSS model, K by default (the one that looked best on our RTX 3080), or J, L, M, default.
• motion: full (default), camera or pack; motion_items=true includes held-item poses.
• sharpening: rcas (default), pack or off; sharpness=0.5 sets RCAS strength from 0 to 1.
• mip_bias: -1.0 by default; move toward 0 for less distant texture shimmer, or use pack.
• forge_early_window: off (the default) or keep, see below.
• timing_log_seconds: log the GPU time of the DLSS passes every N seconds (0 = off).

Good to know

• Forge's early loading window costs about 15 % FPS with Embeddium on NVIDIA cards: it opens the OpenGL context before Embeddium's driver workaround can apply. We measured this without DLSS too (forest 36 FPS with it, 42 without). Once DLSS has run, Bons DLSS Diet switches it off in config/fml.toml (earlyWindowControl=false) and tells you in chat; the next start is faster. You then see Minecraft's own loading screen instead of Forge's early one. Set forge_early_window=keep to leave it.
• The log says what happened: Bons DLSS Diet: wrote "... + DLSS" from ..., DLSS on for ..., or why DLSS stayed off.
• Other Complementary versions, Complementary without Euphoria Patches and Complementary Reimagined are left untouched for now; a pack the mod does not recognise is never changed.
• After a Complementary or Euphoria Patches update the generated folder is rebuilt on the next start as soon as the mod supports the new pair; until then it stays as it is.
• Motion is estimated per object, not per animated vertex. Fine deformation, transparency and moving effects can still produce artifacts. The stronger texture detail and sharpening can increase foliage shimmer; both are adjustable.
• With the Euphoria Patcher mod 1.8.6 and Oculus 1.8.0, Euphoria's "update available" notice can stop the plain Euphoria pack from compiling (final.fsh, "undefined variable _10"). The + DLSS copy is not affected: Bons DLSS Diet leaves that notice out of it.
• To use a newer NVIDIA DLSS library, put its nvngx_dlss.dll in config/bons_dlss_diet/.
