An article published by Igor’s lab confirms that NVIDIA’s frame generation The technology is applied at the back end of the frame processing pipeline and is perfectly compatible with FSR 2.0 and Intel XeSS AI up-scaling pipelines. While this doesn’t add any real benefit, it hasn’t stopped Igor from doing some groundbreaking benchmarks of what the numbers would look like, and surprisingly it seems that FSR+ Frame Generation can actually beat DLSS+ Frame Generation in sheer performance numbers.
AMD FSR + NVIDIA Frame Generation beats DLSS in NVIDIA RTX 4090 benchmarks
Let’s start with some context. Frame generation is a technology that is part of NVIDIA’s DLSS 3.0 stack that generates artificially created frames between two frames generated by the AI implementation of DLSS. Think of these frames as padding between two computationally generated frames. If you are an NVIDIA 4000 series GPU owner, you can actually use NVIDIA frame generation with frames computationally generated by Intel XeSS or AMD FSR 2.0.
Image quality between AMD FSR 2.0 + NVIDIA Frame Generation and DLSS + Frame Generation appears to be fairly comparable, although NVIDIA Frame Generation and Intel XeSS seem to be on the softer side. So, without further ado, here are the benchmarks for all three configurations:
Remember that fps numbers only tell part of the story. To get the full picture we recommend you head over to Igor’s Lab and read up on the frame times, variations and percentiles of the three systems, but for now let’s focus on the maximum fps that can be achieved. With DLSS and FG (Frame Generation) you can see a maximum value of 224 fps. Pretty decent right? Keep in mind that even this value can be a serious software bottleneck due to frame time limitations in the game engine.
Next we have AMD FSR unwrapping the frames in the backend and NVIDIA Frame Generation is used to fill in the gaps. The maximum achievable FPS here in Spider-Man Remastered is 231.4 fps, which is slightly higher than the native approach of using DLSS. However, this appears to be a software bottleneck as other metrics are actually quite comparable to the DLSS-based implementation.
Finally, we have the Intel XeSS + NVIDIA Frame Generation based run, which delivers a maximum achievable fps of 203.9 – which doesn’t appear to be a software bottleneck. As mentioned above, Intel XeSS is also a bit softer in the image quality department than either FSR 2.0 or NVIDIA DLSS.
One thing is for sure though, more testing is needed in titles that support it to see if FSR can actually boost performance when coupled with NVIDIA Frame Generation on RTX 4000 series GPUs – in a title that does not encounter software bottlenecks. Cross-manufacturer compatibility between upscaling technologies is something quite exciting and could result in a “Best of Both Worlds” result for consumers.
