Massive improvements in all areas, most of the news will also be for older cards.
While the main announcement at Nvidia CES was the RTX 50 series of graphics cards with Blackwell architecture, perhaps even more interesting news concerns technologies related to gaming graphics. Juan mentioned them in the presentation, but later we received much more detailed information, and there was very little of it.
DLSS 4
Nvidia has introduced another version of its DLSS technology suite, number 4. It brings Multi Frame Gen as a new feature and also improves existing technologies. You can see how things stand with support for individual series in the visual table below.
Thus, the only exclusive feature of the RTX 50 is Multi Frame Gen.the classic Frame Gen (newly improved) will also run on the RTX 40. RTX 20 and RTX 30 series owners will also get improved scaling, DLAA anti-aliasing and Ray Reconstruction technology.
Generating multiple frames
But let’s move on to individual functions; the main new product is, as already mentioned here, Multi Frame Gen. What are we talking about? Until now, image generation has created one “fake” image between two classically rendered ones. But Multi Frame Gen, thanks to improvements in Blackwell architecture software and hardware can generate 3 images at the same timewhich will provide much higher fluency.
This is achieved with a delay similar to the generation of a single frame using DLSS 3.which is a very respectable performance. However, compared to classic rendering, input lag is still increased, so only the smoothness is really improved, not the traditional FPS increase. Nvidia still promises constant frame rate.
Faster and more efficient frame generation
The original generation of images, which is also available on the RTX 40, has also been improved. Fasterso it can further improve fluency and, perhaps more importantly, it needs less video memory.
It was the memory requirements of some games that prevented the use of this technology on weaker graphics with limited video memory; we hope this can now change.
Transformer model
All players with RTX graphics will be interested in improvements in DLSS upscaling, DLAA anti-aliasing and Ray Reconstruction, because all three technologies are moving to the so-called Transformer model.
Nvidia has been using CNN networks so far, but says it has reached the limit of its capabilities. Transformer model can better identify patterns and at the same time it scales and fits much better up to twice the parameters vs. CNN.
Upscaling
When it comes to upscaling, the Transformer model can provide not only general higher image quality or less ghostingbut also much more better preserves texture detailsas seen in the Horizon Forbidden West trailer.
Ray Reconstruction
Ray Reconstruction also brings significant image quality improvements from the Transformer model, especially in scenes with complex lighting. NVIDIA promises higher detail, less ghosting and reduced flickeras seen in the Alan Wake 2 trailer.
Wide game support
DLSS 4 should arrive with RTX 50 graphics cards, that is, on January 30, while on the day of release it will have support in 75 titles (list here). The improved version of upscaling and anti-aliasing will only be available in beta for now and will need to be enabled in the Nvidia app.
Reflex 2
In addition to DLSS 4, Reflex 2 technology was also introduced. The original Reflex takes care of reducing latency by about 50% thanks to better CPU and GPU synchronization, but Reflex 2 goes much further as it introduces the concept of the so-called Frame Warp.
Nvidia describes the technology this way: While a frame is being rendered on the GPU, the GPU is already calculating the camera position for the next frame. Reflex 2 afterwards takes this position and moves it to the previous framewhich is rendered by the GPU. The camera position is updated very frequently, so the latest version is always available.
Of course, such a shift would disrupt the entire scene and the pixels will changebut Nvidia solves this on its own predictive algorithmwhich uses camera, color and depth data from previous images to filled the pixels correctly.
Reflex 2 should bring another 50% reduction in latencywhat will it be approximately 75% lower than native rendering without Reflex.. Unlike the first Reflex, which mainly helps with GPU limitations, Reflex 2 is capable of can also be used well in games limited by CPU performance.which are often competitive games where technology will come first anyway.
Currently support Final And valiantalthough we don’t know the exact release date yet. Reflex 2 will be the first game released for the RTX 50.but we will only talk about exclusivity of timeshould arrive later on all RTX graphics cards.
