AMD Radeon Super Resolution feels like the wrong play against Nvidia DLSS

AMD announced a new upscaling feature at CES 2022, Radeon Super Resolution (RSR), and it’s built on the company’s FidelityFX Super Resolution (FSR) upscaling feature. Instead of coming through supported games, though, it comes through AMD’s drivers, allowing it to work with virtually any game.

It’s interesting timing, coming just a couple of short months after Nvidia brought a very similar feature back into the limelight. I’m happy that RSR is here, but it’s the wrong move for AMD in the increasingly competitive space of upscaling.

Back and forth (and back again)

Nvidia revitalized Nvidia Image Scaling (NIS) in November 2021. The company has offered NIS for the past two years as a driver-level upscaling feature, but in response to the growing popularity of FSR, Nvidia released a version that developers could add directly to games.

AMD is doing the opposite. The company released FSR as an open-source platform, allowing developers to add upscaling tech to their games. RSR is the driver-level bit, opening the floodgates for upscaling in all games on AMD graphics cards.

It’s not a bad feature, but it’s not the right step for AMD. There’s little doubt in my mind that AMD released RSR as a way to combat NIS, forgetting that this whole upscaling battle is focused on Nvidia’s Deep Learning Super Sampling (DLSS).

FSR has and will continue to be a marketing play for AMD. From the jump, it was positioned as a competitor to DLSS, despite sharing little to no technical DNA with Nvidia’s upscaling feature. And RSR looks like the same thing, announced alongside AMD’s products in what is likely the biggest stage the company will present on for the whole year.

The back and forth between AMD and Nvidia is ultimately a good thing. But it can lead to situations like RSR, where one company is pushing a feature that itself isn’t pushing the market forward. RSR is good, but an update to FSR would be much better.

Where have the last six months gone?

Six months have flown by. AMD released FSR on June 22, 2021. In that time, the company has added support for several dozen games, which is an impressive feat. But it doesn’t require much from AMD. FSR is open-source and available to developers free of charge.

It’s no secret that FSR needs some work when it comes to image quality, and AMD has been open that the current version is far from the last. Six months isn’t enough time for FSR 2.0, but it’s certainly enough time to hone the upscaling algorithm of FSR 1.0 to improve image quality.

I don’t want to mince words: We should have RSR. But it’s not a replacement for an enhanced version of FSR, and it’s not the right move for AMD against the upscaling monolith Nvidia has established.

The best feature of FSR is that it supports all graphics cards. RSR only supports AMD graphics cards through the driver, and although it’s a nice feature to have for AMD cards, it does very little to separate the feature set from the Nvidia competition.

AMD vs. Nvidia at Computex 2022: Where were all the GPUs?
amd radeon rx 6950 xt review 6

Computex 2022 might be in full swing, but if you were hoping for exciting news from the two big graphics card manufacturers, then the show's already over. AMD's keynote contained tantalizing teases of next-generation processors and a few laptop showcases, while Nvidia's focused on AI developments and datacenter graphics cooling.

And that's it. No RDNA 3, no RTX 4000, no GTX 1630, and not even a nudge and a wink that we might want to update our power supplies soon.

Nvidia calls out AMD about GPU drivers. Is it hypocritical?
GPU inside the MSI Aegis RS 12.

Yesterday, Nvidia published a blog post (and an accompanying video) about the importance of well-developed and well-designed GPU drivers, and included a dig at AMD in the process.

Most of the article reads just like any blog post from the desk of a company like Nvidia -- explanatory and full of infographics. It's not a particularly eye-catching article, until it mentions beta drivers and Windows Hardware Quality Labs (or WHQL) certification. This section of the blog post is seemingly a (not entirely) subtle jab at AMD's beta video drivers.

Finally, budget GPUs from AMD and Nvidia are a reality again
Pricing information for the AMD RX 6500 XT graphics card.

Nvidia and AMD announced new budget graphics cards at CES 2022: The $199 RX 6500 XT for AMD, and the $249 RTX 3050 for Nvidia. Even with rumors of these cards floating around, I didn't expect to actually see them -- and I didn't expect AMD and Nvidia to price them around $200.

Prices of graphics cards have been going up, and over the past few generations, Nvidia and AMD have continued to distance their mainline products from their budget offerings. CES 2022 forced AMD and Nvidia to reckon with the current prices of graphics cards, and the RX 6500 XT and RTX 3050 seem like a winning pair in a time when graphics options are few and far between.
