If you’re interested in how different rescaling technologies compare, today’s your lucky day. We’ve come across an interesting comparison of rescaling technologies that includes the NVIDIA frame generation technology.
The most interesting thing about this rescaling technology is that it works with other technologies beyond NVIDIA DLSS itself – namely the AMD FidelityFX super resolution and Intel XeSS. This gives us an idea of what future updates to these products might look like.
Nvidia’s DLSS 3.0 offers best performance for frame generation
if there‘s no significant improvements to NVIDIA DLSS 3, they‘ve added the possibility of generating extra frames with AI. This could potentially increase refresh rates significantly. The tech uses Tensor Cores to add an AI–generated frame in between two real 3D-rendered frames (of course, game compatibility is required for this).
However, there are some downsides to using this technique , namely increased input lag. Nvidia Reflex is required in all games that support DLSS 3.0 to combat the issue of slow mouse and keyboard actions.
NVIDIA DLSS 3.0 offers the best performance when it comes to creating native resolution frames or upscaling other resolutions, according to a performance comparison test conducted by Igor‘s Lab. AMD FSR 2.1 and Intel XeSS are both decent at rescaling tech, but NVIDIA Frame Generation takes the cake in this department ,especially when used separately to create either lower or higher–resolution images.
The GeForce RTX 4090 outdoes the competition in raw performance
The game selected for this purpose, Spider-Man Remastered , is compatible with all three technologies and allowed for an apples-to-apples comparison of their capabilities. GeForce RTX 4090 is the only NVIDIA GPU compatible with DLSS 3.0, so we used it in our testing.
When it comes to raw performance, Framer’s GeForce RTX 4090 blows the competition out of the water with a whopping 167.6FPS. But when you take into account that Intel XeSS can offer 168.5FPS at a higher than native resolution, things start to look a lot more even-handed.
Upscaling technologies in quality mode give Intel technology an edge, offering 183fps compared to the 193.8 fps of AMD FSR and the 197.4 frames per second of NVIDIA DLSS. Not too shabby! In balanced mode (Quality/Fluidity), XeSS achieves 192.7 fps while FSR 206.8FPS and DLSS 209fps. And in performance mode, XeSS comes out on top again with a203.9FPS before the 220.1FPS offered by DLSS and 220.5 fps of FSR ,nice! In short, Intel XeSS is right up there with NVIDIA DLSS and AMD FSR when it comes to raw performance figures.
This technology isn’t just about raw numbers
There can be big performance differences at very precise times, although we only have images to go off of for comparison. These are static though, so we don’t get to see how this tech works on the move and if it creates any anomalies. At least NVIDIA showed us a concept of what AMD’s future FSR 3.0 will look like. Interestingly, FSR 3.0 won’t come out until 2023 but with NVIDIA’s help, it’ll be able to do what 2..1 is already doing- generate these frames through AI to trigger the fluidity of the games.
