NVIDIA at Gamescom 2026: DLSS 4.5, RTX Spark, RTX Remix, ACE and GeForce NOW announcements

NVIDIA has used Gamescom 2026 to announce a broad set of updates across its GeForce ecosystem, covering DLSS 4.5, RTX Remix, NVIDIA ACE, RTX Spark, GeForce NOW and the NVIDIA App. Some of these technologies were announced earlier in the year, so the focus at Gamescom is largely on new games, integrations, compatibility and availability. RTX Spark is getting more of the gaming ecosystem support it needs ahead of launch, RTX Remix is gaining two sizeable community projects, NVIDIA ACE is heading to Aniimo, and GeForce NOW is expanding across both content and platforms. Here is everything new NVIDIA announced at Gamescom 2026.

DLSS 4.5 – Ray Reconstruction goes live

NVIDIA has confirmed that 007 First Light and Control Resonant will both support DLSS 4.5 Ray Reconstruction and path tracing in the coming days. 007 First Light is scheduled to receive the technologies on September 15, while Control Resonant will support them on September 24. NVIDIA has also made the second-generation Ray Reconstruction technology available through the Streamline SDK and an Unreal Engine plugin for developers. The company clarified during its Gamescom briefing that DLSS 4.5 Ray Reconstruction will not automatically work across every title supporting another DLSS 4.5 feature. Instead, it will initially be available for a selected group of compatible games.

The major update here is that DLSS 4.5 Ray Reconstruction itself is now available from August 25 through DLSS Override in the NVIDIA App for supported titles. The new model builds on NVIDIA’s second-generation transformer architecture and introduces deeper spatial awareness, finer developer control over temporal accumulation and a more efficient denoiser. NVIDIA says it processes around 20 per cent more parameters while using approximately 35 per cent more compute, with the goal of improving lighting accuracy, shadow quality and stability in motion. DLSS 4.5 Ray Reconstruction is also being brought to RTX Remix, allowing compatible Remix projects to use the newer reconstruction model.

RTX Remix

One of the more substantial Gamescom announcements is a major expansion of Painkiller RTX, an RTX Remix project created by Merry Pencil Studios. The project now remasters the first 15 levels of the original Painkiller, with fully path-traced graphics and DLSS 4.5. The mod also incorporates RTX Volumetrics, advanced particle effects, NVIDIA Neural Radiance Cache, Remix Logic and RTX IO. NVIDIA says RTX IO has been used to reduce the mod’s file size from around 57 GB to approximately 45 GB through GPU-accelerated decompression. Remix Logic is being used to connect modifications with events within the original game, including enabling the Demon Morph mechanic to be manually triggered. Painkiller RTX will be available as a free mod for owners of the original Painkiller on GOG, with a demo available from August 25.

NVIDIA also revealed an early version of The Elder Scrolls III: Morrowind RTX, an RTX Remix community project being developed by modder GokuwasHere. The current build remasters Seyda Neen, the Mages Guild and Balmora, with fully path-traced rendering, upgraded textures and materials, RTX Volumetrics, advanced particle effects, Neural Radiance Cache and RTX IO. The project also adds new foliage and rock scattering, volumetric clouds and upgraded water reflections. Selected gameplay mods are being incorporated alongside the visual overhaul. There is no release date yet, and the project is still looking for contributors.

Alongside the new mods, NVIDIA also provided an update on RTX Remix itself. More than 240 games are now compatible with RTX Remix, with nearly 100 titles added during 2026. NVIDIA also says RTX Remix mods have now been downloaded more than 3.8 million times. The wider ecosystem is expanding too, with Remix/Blender integration for managing assets, InstaMAT2Remix for procedural asset generation and the community-led PCSX2 Remix project exploring path-traced modifications of PlayStation 2 games.

NVIDIA ACE with guardrails

NVIDIA is bringing NVIDIA ACE to Aniimo, the upcoming free-to-play open-world RPG. The integration will allow players to speak naturally with their Aniimo companions, teach them skills such as crafting and mining, coordinate in-game actions and discover individual personalities through conversation. The functionality will run locally on RTX GPUs and is scheduled to arrive in early 2027.

Obviously, whenever AI is mentioned, the notion of jailbreaking LLMs does come into the picture and NVIDIA stated that developers can prevent AI-controlled characters from bypassing normal game systems. And that developers retain control over model instructions, permitted actions and response guardrails. For example, in Aniimo, NVIDIA said the AI functionality will be limited to the player’s home area and restricted to selected activities, including crafting, mining and resource gathering. ACE itself has been demonstrated previously in projects such as Krafton’s PUBG Ally. 

RTX Spark get more gaming support

The biggest RTX Spark news at Gamescom concerns gaming compatibility, particularly around anti-cheat support on Windows on Arm. EA is bringing its Javelin anti-cheat system to RTX Spark. According to NVIDIA, this will allow games including Apex Legends and EA’s Formula One titles to operate on RTX Spark systems. That is a significant addition because anti-cheat support has been one of the main questions surrounding Windows-on-Arm gaming.

Embark Studios is also supporting RTX Spark, with both ARC Raiders and THE FINALS confirmed for the platform. Ubisoft is joining the platform as well, with NVIDIA specifically showing Anno 117: Pax Romana as part of the publisher’s RTX Spark support. NVIDIA says a wider group of studios and publishers is working on compatibility, including Capcom, CD Projekt Red, Krafton, Riot Games, Sega, Xbox, NetEase Games, Konami and others.

RTX Spark itself was announced earlier at Computex and in just a few months, NVIDIA has begun to fill out the game, publisher and anti-cheat support required for RTX Spark to function as a mainstream gaming platform when systems arrive later this autumn.

GeForce NOW

NVIDIA has several Gamescom announcements around GeForce NOW, beginning with new games that will be available on the service at launch. The company showcased titles including 007 First Light, Gears of War: E-Day, The Blood of Dawnwalker, Control Resonant, Onimusha: Way of the Sword and Metro 2039. And NVIDIA is also launching a Control Resonant GeForce NOW membership bundle. For a limited period, customers purchasing a 12-month GeForce NOW membership will receive the game when it launches.

More importantly, the GFN service is expanding to more platforms too. Firefox now gets official GeForce NOW support, joining Chrome, Safari, Edge and Opera. NVIDIA is also extending GeForce NOW further into Valve’s ecosystem. Support is coming to Steam Machine, while Steam Controller support is planned for later in Q4. Steam Deck and Steam Machine support will arrive first, followed by Steam Controller integration across the Windows and macOS native applications.

Amazon integration is expanding as well. GeForce NOW is coming to additional Fire TV hardware, including the Fire TV 4K Select, while NVIDIA plans to allow users to purchase GeForce NOW memberships directly through Amazon on supported Fire TV devices later this year. 

As for updates on promises, there’s GOG account linking and library synchronisation, which now has an availability date of August 27. Users will be able to link NVIDIA and GOG accounts and automatically synchronise compatible titles from their GOG libraries. Six additional GOG games are being added initially, including Baldur’s Gate 3, Kingdom Come: Deliverance II and Clair Obscur: Expedition 33. NVIDIA says more GOG titles will be added every month. 

Then there is the arrival of DLSS 4.5 controls for GeForce NOW Ultimate members. Users will be able to manage DLSS Super Resolution, Dynamic Frame Generation and Ray Reconstruction across hundreds of supported games. NVIDIA believes Dynamic Frame Generation could also help produce smoother GeForce NOW streams, although the company said it will provide more information on that implementation in September.

NVIDIA App

The NVIDIA App is receiving several additional graphics controls as part of its August update. Users will be able to enable DLSS 4.5 Ray Reconstruction through DLSS Override in supported games, giving existing integrations access to the newer model without waiting for a game-specific update. 

NVIDIA is also adding per-application Resizable BAR controls, allowing users to enable or disable the feature separately for individual games. G-SYNC Pulsar controls are being moved into the NVIDIA App as well, allowing supported displays to be configured without relying entirely on the monitor’s own on-screen interface..

Overall, NVIDIA’s Gamescom 2026 announcements are largely about broadening the reach of technologies introduced earlier in the year. RTX Spark is getting the publisher and anti-cheat support required to make Windows-on-Arm gaming more viable, RTX Remix is gaining new projects and tools, ACE is expanding into another game, and GeForce NOW continues to widen both its game catalogue and the number of devices from which it can be accessed.
