Article posted by Igor lab Ensures that NVIDIA’s frame generation technology is implemented at the end of the frame processing pipeline and is fully compatible with the FSR 2.0 and Intel XeSS AI Up-scaling pipelines. While there wasn’t any real advantage to doing that, it didn’t stop Igor from taking some leading benchmarks for what the numbers would be, and surprisingly, it looks like FSR + Frame Generation can actually beat DLSS + Frame Generation in pure-number performance.
AMD FSR + NVIDIA Frame Generation outperforms DLSS in NVIDIA RTX 4090 benchmarks
Let’s start with some context. Frame Generation technology is part of NVIDIA’s DLSS 3.0 package that creates artificially generated frames between two frames created by an AI DLSS application. Think of these frames as padding between two computationally generated frames. As it turns out, if you’re an NVIDIA 4000-series GPU owner, you can actually use NVIDIA frame generation with frames that are algorithmically generated by Intel XeSS or AMD FSR 2.0.
Image quality between AMD FSR 2.0 + NVIDIA Frame Generation and DLSS + Frame Generation looks somewhat comparable although NVIDIA Frame Generation and Intel XeSS seem to be on the smoother side of things. So without any further ado, here are the benchmarks from all three configurations:
Keep in mind that the fps numbers only tell part of the story, to get a full idea we encourage you to head over to Igor’s lab and read up on the frame times, changes and percentage numbers for the three systems but for now, let’s focus on the maximum fps achievable. With DLSS and FG (frame generation), you’re looking for a maximum value of 224 fps. Pretty decent isn’t it? Keep in mind that even this value could be a serious software bottleneck due to timeframe limitations in the game engine.
Next, we have AMD FSR bring out the frames at the back end and use NVIDIA Frame Generation to fill in the gaps. The maximum FPS that can be achieved here in Spider-Man Remastered is 231.4 fps, which is slightly higher than the original method of using DLSS. However, this appears to be a bottleneck in software because other metrics are somewhat comparable to a DLSS-based implementation.
Finally, we have Intel XeSS + NVIDIA Frame Generation based playback which produces a maximum achievable FPS of 203.9 – which doesn’t seem to be a software bottleneck. As noted above, Intel XeSS is also a bit softer in the image quality department than FSR 2.0 or NVIDIA DLSS.
One thing is for sure, however, is to run further tests in titles that support this to check if FSR can actually increase performance when paired with NVIDIA Frame Generation on RTX 4000 GPUs – in an address that doesn’t experience software bottlenecks. . Vendor-compatibility of scaling technologies is very exciting and can lead to the best of both worlds outcomes for consumers.
