SIRIS 1.3.0 (Minecraft 26.3)

Experimental, Windows + NVIDIA RTX only. Install, requirements and Lunar notes: README. Replace siris-1.2.2+mc26.3.jar with this one; your settings stay.

SIRIS 1.3.0

• Frame Generation up to 6x. "Generated frames" now offers 5x and 6x when the GPU and driver support them (RTX 50 with a recent driver). The list only shows the modes your card can do; RTX 40 stays at 2x. Not tested on an RTX 50 card yet, feedback welcome.
• The latency in the overlay now counts from the start of the frame (when the game reads your input) until the real frame goes to the screen. It reads 2-3 ms higher than before for the same thing; nothing got slower.

Works with VIRIS if you want Voxy LODs on Vulkan. It is not required.

SIRIS 1.2.2 (Minecraft 26.3)

Experimental, Windows + NVIDIA RTX only. Install, requirements and Lunar notes: README. Replace siris-1.2.1+mc26.3.jar with this one; your settings stay.

SIRIS 1.2.2

• No crash in full screen without VSync on Windows on Arm. On an RTX Spark N1X the NVIDIA driver crashed when the presenter tagged frames for timing without VSync. Those tags are now only used with VSync, where they pace the frames. On x64 nothing changes in pacing (same fps with VSync, slightly more without it).
• The native bridge can now be built on Windows on Arm (Arm64). This jar still carries the x64 bridge only, so it does not load on an Arm64 Java yet.

SIRIS 1.2.1 (Minecraft 26.3)

Experimental, Windows + NVIDIA RTX only. Install, requirements and Lunar notes: README. Replace siris-1.2.0+mc26.3.jar with this one; your settings stay.

SIRIS 1.2.1

• Frame Generation no longer smears while you turn. DLSS-G got its motion vectors scaled far too small, so it saw almost no motion. Generated frames now stay sharp on fast turns instead of smearing trees and block edges, and with x3/x4 the extra frames really move between the rendered ones instead of fading (most visible with the driver's FG Lite). Same fps. Found and fixed by @MichaelMKenny (#2).

SIRIS 1.2.0 (Minecraft 26.3)

Experimental, Windows + NVIDIA RTX only. Install, requirements and Lunar notes: README. Replace siris-1.1.6+mc26.3.jar with this one; your settings stay.

SIRIS 1.2.0

• The HUD stays sharp with Frame Generation. Text, chat and the crosshair no longer leave ghost copies in generated frames while you turn: DLSS-G now gets the GUI's opacity and keeps those pixels out of its frame blending. Costs about 2 % fps. If a driver can't do it, Frame Generation runs as before.
• The mod's metadata lists NVIDIA's RTX SDK license next to MIT for the bundled DLLs; the README carries NVIDIA's attribution.
• Plainer wording in the settings texts.

SIRIS 1.1.6 (Minecraft 26.3)

Experimental, Windows + NVIDIA RTX only. Install, requirements and Lunar notes: README. Replace siris-1.1.5+mc26.3.jar with this one; your settings stay.

SIRIS 1.1.6

• Mobs and the hand keep the shader pack's look at night. With packs like Solas they were drawn by the game's own shader after joining: too bright, no shadows. The first join in a session now reloads the pack, so that join takes 1-2 s longer. Later joins skip it.
• The presenter can't freeze the game as easily. If it takes no frame for 5 s, the game goes back to its own output instead of hanging, and shutting down no longer waits on it forever. This is hardening for a report of a game stuck in the main menu on an RTX 3060. That report wasn't reproduced, so it may not be solved.
• New option "Limit to monitor" (off by default): with Frame Generation and no VSync, shown frames stay just under the monitor's refresh rate. Rendered fps drop with it.
• The status line shows motion judder, a measure of how evenly frames are paced.

SIRIS 1.1.5 (Minecraft 26.3)

Experimental, Windows + NVIDIA RTX only. Install, requirements and Lunar notes: README. Replace siris-1.1.4+mc26.3.jar with this one; your settings stay.

SIRIS 1.1.5

• No change in the game. VIRIS moved to its own repository, so this repository and its releases are only about SIRIS now.

SIRIS 1.1.4 (Minecraft 26.3)

Experimental, Windows + NVIDIA RTX only. Install, requirements and Lunar notes: README. Replace siris-1.1.3+mc26.3.jar with this one; your settings stay.

SIRIS 1.1.4

• Voxy LODs keep their colour when you join a world again. With VIRIS and a shader pack, every join after the first showed the LODs as grey outlines until the pack was reloaded. SIRIS skipped Vitrail's pack reload on joining (to save a short hitch); with VIRIS installed it no longer does.

SIRIS 1.1.3 (Minecraft 26.3)

Experimental, Windows + NVIDIA RTX only. Install, requirements and Lunar notes: README (shader packs through Vitrail). Replace siris-1.1.2+mc26.3.jar with this one; your settings stay.

SIRIS 1.1.3

• DLSS model M is the new default. Model K turned the shader packs' animated noise (light shafts, fog) into a fine grid of dashes, most visible over distant terrain at sunrise and sunset. M gives a clean picture and costs about 1 ms more per frame than K.
• Configs that still have the old default K switch to M once on the first start. If you pick K again afterwards, it stays.
• The model tooltips explain the trade-off (Video Settings → DLSS → Model).

SIRIS 1.1.2 (Minecraft 26.3)

SIRIS 1.1.2: the mod is now called SIRIS (formerly PYRAXIS / Iris DLSS Bridge). Rendering is unchanged from 1.1.1.

Updating

• Remove the old iris-dlss-*.jar from mods/. The jar is now called siris-1.1.2+mc26.3.jar; with both in the folder, both load.
• Your settings carry over: config/iris-dlss.properties becomes config/siris.properties on the first start.
• The old iris-dlss/ folder in the game directory can be deleted.
• Log lines now start with SIRIS:.

PYRAXIS 1.1.1 (Minecraft 26.3)

Experimental, Windows + NVIDIA RTX only. Install, requirements and Lunar notes: README (shader packs through Vitrail). Replace iris-dlss-1.1.0+mc26.3.jar (or any older iris-dlss-*.jar) with this one; your settings stay.

Changed in 1.1.1

• Orange theme. The settings screen (Mod Menu) and the DLSS page in Sodium's video settings now use the icon's orange (#FF6A3D) instead of NVIDIA green.
• Icon in Sodium's settings list next to the DLSS page, like other mods show theirs.

Everything from 1.1.0 is included.

Files

• iris-dlss-1.1.1+mc26.3.jar: this mod (NVIDIA's DLSS runtime inside).
• voxy-vulkan-0.1.1+mc26.3.jar: optional, Voxy LODs on Vulkan without a shader pack (unchanged since 0.7.0).
