Fsr Redstone Tested: Amd's Long Awaited Ai-powered Frame Gen...

Actually, it's not FSR Redstone. It's all just FSR now because of reasons that only make sense to AMD.

It's been almost seven months since it was first announced, but at long last, AMD's much-vaunted machine learning-powered update to FSR is finally here. With the AMD Adrenalin 25.12.1 driver releasing today, you too can get on the new FSR bandwagon. So long as you have an RDNA 4 card, that is. Better known as FSR 'Redstone', the work done here essentially brings AMD on par with Nvidia and Intel, in terms of applying AI to upscaling, frame generation, and other rendering technologies.

However, it's worth pointing out now that AMD still doesn't have multi-frame generation, so it's not quite at the same level. It's also a little too early to tell whether the new FSR frame generation is as good as DLSS MFG or XeSS-MFG in terms of image quality, and that's because it only works on a relatively small number of games.

Something else that I need to get out of the way is AMD's bizarre decision to drop any numbering with FSR. For example, FSR 4 was announced in February and brought AI-powered upscaling to games on RDNA 4 graphics cards.

That's now simply called AMD FSR Upscaling. But that's also the same name for FSR 3's upscaler. And FSR 2. But they don't use machine learning, so to help differentiate between them all, AMD's more expansive terminologies are AMD FSR Upscaling (Analytical) and AMD FSR Upscaling (ML).

It's the same thing with FSR 3 Frame Generation: that's now called AMD FSR Frame Generation (Analytical), with the new one in Redstone sporting the same label with ML in parentheses. I'll come back to this later, as it's something that's bugging me a touch (just a touch? -Ed.).

FSR Redstone introduces three items, though one has already been released (FSR Ray Regeneration), and of the two remaining, FSR Frame Generation and FSR Radiance Cache, the latter isn't available to preview and won't appear in games until next year anyway. So that means the entirety of my FSR Redstone testing consists of the new frame gen system.

Good job it's bang on the money, then. For the same reasons that FSR 4 upscaling is so much better than FSR 3, the use of AI to calculate the colours for the generated frame means that you can pretty much wave goodbye to almost all of the weird artefacts that you get with FSR 3 frame gen.
