AMD won’t optimize Nvidia graphics cards for Super Resolution

AMD is set to release its new FidelityFX Super Resolution technology this month. The tech is its response to Nvidia’s Deep Learning Super Sampling (DLSS), an upscaling technology that improves gaming performance. Although AMD made FSR open-source and cross-vendor, Radeon’s vice president states that the feature will not be optimized for Nvidia cards.

FidelityFX Super Resolution is a much-anticipated technology that might shake things up on the upscaling front for both AMD and Nvidia. As it’s said to offer up to twice the performance in games in 4K with ray tracing enabled, it stands a chance at challenging Nvidia’s DLSS. 

FSR reconstructs the image to make it appear like it’s rendering at a higher resolution. This might make a game that was initially 1080p appear to be 1440p. According to AMD, FidelityFX is a spatial upscaling technique that doesn’t rely on motion vectors or history buffers.

While FSR was made to be a competitor to Nvidia’s DLSS, it doesn’t work the same way. Nvidia’s tech is artificial intelligence-based, but FSR does not use any machine learning. However, AMD revealed that FSR will use a combination of linear and nonlinear upscaling as opposed to Nvidia’s strictly deep learning approach.

AMD’s new ray-tracing solution is going to be fully open-source. The company has previously spoken about the benefits of going open-source as well as cross-vendor, promising that FSR would function even on non-AMD graphics cards. However, it seems that this promise will not become reality until Nvidia itself makes it happen.

Scott Herkelman, the vice president and general manager of Radeon, announced on Twitter that the new technology will not be available to Nvidia users. He explained this by saying: “Just to be clear, though — we aren’t optimizing it for GeForce. That will be up to them to do the work on behalf of their gaming community — we just proved it works.”

This may come as a disappointment to some users who do not own a Radeon card. Collaboration between the two brands may happen, but it’s definitely not a guarantee. The ball is in Nvidia’s court and the company may not be willing to spare resources on optimizing FidelityFX to work on GeForce GPUs.

FSR is an interesting solution that could dethrone DLSS at some point in time. However, as of right now, Nvidia is likely to maintain the upper hand due to the performance differences between the two. With FidelityFX Super Resolution launching on June 22, we will just have to wait for Nvidia’s response to know whether FSR will make it to GeForce cards.

Nvidia’s RTX 4070 Ti is destroying AMD, even though it shouldn’t
The RTX 4070 Ti graphics card on a pink background.

Despite the fact that the RTX 4070 Ti has been reviewed poorly, Nvidia's latest GPU seems to be doing well in terms of sales numbers -- at least as far as the European market is concerned.

According to newly published sales figures, Nvidia managed to sell a huge quantity of RTX 4070 Ti GPUs. It effortlessly defeated its biggest rival, AMD, even though the AMD RX 7900 XT is the better value. Regardless of how it's reviewed, the RTX 4070 Ti seems to be the king of all the new graphics cards that have out in 2023 so far.

I switched to an AMD GPU for a month — here’s why I don’t miss Nvidia
RX 7900 XTX slotted into a test bench.

AMD's RX 7900 XTX currently tops Digital Trends' list of the best graphics cards. But there's more to a GPU than just performance testing and benchmarks, and some of those things can't be discovered until you live with a piece of tech day in and day out.

So, I figured it was high time to put my proverbial money where my mouth is by using AMD's card every day in my own PC. And a month later, I'm happy to report that aside from some minor hiccups, I don't miss Nvidia as much as I thought I would.
