Inworld AI announced that Meta's reasoning and coding model Muse Spark 1.3 is now live on Inworld Realtime Router, with closed weights, support for a 1M token context, and pricing of $1.25 per 1M input tokens and $4.25 per 1M output tokens. According to its disclosure, in Meta's internal coding tests, this version uses about 25% fewer tokens than Spark 1.2.
A space-agnostic visual game analytics tool for mixed reality (MR) game development has been proposed, combining adaptive spatial reconstruction with realtime object detection and running on the Microsoft HoloLens 2 MR headset. The tool is designed for the complexity of MR games, which must integrate real-world and digital components, and for the difficulty existing visual analytics tools have in achieving space-agnostic generalization. The researchers hope it will deepen understanding of players' surroundings and open a new direction for visual analytics in MR game development.
The paper proposes SALFT (Selective Affective Layer Fine-Tuning), a framework that fine-tunes a Video Vision Transformer using a selection criterion based on layer-wise parameter L2 norm change to recognize changes in player arousal from gameplay footage.
Why it matters: The paper uses layer-wise parameter L2 norm change as its selection criterion and shows that updating only about 8% of parameters approaches full fine-tuning, useful for comparing compute costs against your own player emotion recognition pipeline.
GDC released a replay clip discussing how the Kingdom Come: Deliverance II team handles crime perception at far and mid LOD. The material comes from the session Supporting Thousands of NPCs in 'Kingdom Come: Deliverance' & 'Kingdom Come: Deliverance II'; the full session is available on GDC Vault: https://gdcvault.com/
Rather than porting the previous game, RUST LTD rewrote H3VR2 from scratch in a brand-new Unity project, spending nearly six months first on architecture and tools. The team numbers more than 20 people, firearm internals are simulated by an in-house system, and ballistics are built on ECS for Unity and Burst; the project moved from H3VR to Unity 6.3, with an emphasis on the SRP Batcher, shader compilation improvements and tile post-processing.
NVIDIA announced this month's updates for RTX game developers, including DLSS 5 with 3D-Guided Neural Rendering controls, speech pipeline extensions and inference framework updates for NVIDIA ACE, and RTX Kit 2026.3, which includes RTX Mega Geometry 2.0. The official tweet links to the developer blog post for this update; capabilities and integration details are in the original on developer.nvidia.com.
Why it matters: The official post lines up DLSS 5, NVIDIA ACE and RTX Kit updates side by side, so developers can compare integration priorities and upgrade order for their own projects.
NVIDIA announced at Gamescom that publishers including EA, Embark and Ubisoft will bring games and anticheat support to RTX Spark, which launches this fall, with EA Javelin Anticheat also natively supporting the platform.
Why it matters: The partner list ahead of RTX Spark's fall launch grows from May's COMPUTEX to this Gamescom, so readers can compare the two batches of publishers to gauge how adoption of the new platform is progressing.
