AMD FSR Redstone feature may not debut in Warhammer 40K Darktide, despite demoing the tech

While FSR Radiance Caching has been shown in action as part of Warhammer 40,000: Darktide, this footage is more tech demo than reflective of active development plans.

AMD FSR Redstone is here but the wait for FSR Radiance Caching just hit an unexpected bump as the feature may not arrive in the game used to demo it anytime soon, if at all. Team Red has shared a demo of the tool running in Warhammer 40,000: Darktide in the interim, but there are no immediate plans to make it publicly available according to the game’s developer.

This slightly puzzling news comes from a press release shared by Games Press. Darktide developer Fatshark states that “the features demonstrated in the video are not currently planned for release in Darktide’s live build.” The reason for this is due to FSR Radiance Caching requiring further development and optimisation.

One could interpret Fatshark’s comments as absolute, in that the developer will never support FSR Radiance Caching in its game. However, I believe they’re more reflective of an immediate position. With some extra time in the oven, I suspect we’ll see the feature make its way into Darktide. This is a particularly confident suspicion, as the studio has a demonstrable appetite for bleeding-edge features, as the first-person shooter supports all upscaling solutions and a bevy of other graphics enhancements.

More importantly, we should absorb the images and videos we’ve seen of FSR Radiance Caching in action with plenty of scepticism. There’s nothing inherently wrong with AMD using a bespoke tech demo to demonstrate this feature, but it’s clear the feature is a way off from debuting in any game, let alone Darktide. This doesn’t necessarily mean AMD is overpromising in terms of image quality and efficiency, as this extra development time could net improvements to both.

While I’m content to give AMD the benefit of the doubt for the moment, having to do so does come with a hint of disappointment. The rollout of FSR Redstone feels somewhat rushed to meet that 2H 2025 deadline shared during its Computex announcement. With FSR Radiance Caching arriving in 2026, FSR Ray Regeneration having limited reach, and no changes to FSR Upscaling, the only major change for Radeon RX 9000 GPUs is ML-based FSR Frame Generation.

It’s hard not to view the package of FSR Redstone as incomplete at present given that context, particularly as FSR Radiance Caching has no firm confirmation of arrival, and FSR Ray Regeneration is locked behind the confines of Call of Duty Black Ops 7’s multiplayer and zombies modes. If AMD is serious about levelling the playing field with Nvidia, it needs to introduce features with substantial rollouts to combat the already deep integration of DLSS 4.

Perhaps we’ll see something of that description at AMD’s CES 2026 press conference on Jan 5, 2026. Club386 will have boots on the ground at the tradeshow, so make sure you’re following us on Google News so you don’t miss any key developments or announcements.
