VXGI enables programmers to place dynamic light sources in a game’s environment. The image on the left was rendered by Nvidia’s GeForce GTX graphics processor. The image on the right is a NASA photograph of the first Apollo moon landing.
These images demonstrate the capabilities of Nvidia’s new lighting technology. Herkelman says MFAA is up to 30 percent faster than MSAA. The technique, according to Nvidia, delivers results that are very similar to MSAA without the performance hit that MSAA exacts. Nvidia’s Multi-Frame Anti-aliasing (MFAA) functions in a similar fashion, but it samples pixels over two frames while rotating the pixels.
For all its effectiveness, MSAA is very computationally expensive and can significantly reduce frame rate when it’s enabled in a game. In 4X MSAA, four samples of each pixel are taken. MSAA works by having the GPU sample multiple locations of each pixel in a scene, and then fully rendering and combining those pixels in the image that’s ultimately rendered on the display. Anti-aliasing, obviously, is a means of coping with this phenomenon, and multi-sample anti-aliasing (MSAA) is the most effective technique. In the most common examples, non-square images can have jagged edges, and moire can spoil the detail in intricate patterns. Note the image quality of the grasses in this scene.Īliasing describes the visual distortion that occurs when a GPU renders an image. Nvidia provided this screenshot to show the capabilities of its Dynamic Super Resolution.
Scott Herkelman, general manager of Nvidia’s GeForce business unit, demoed the effect for me at a briefing on Tuesday, and it is impressive. The feature is enabled by default in Nvidia’s GeForce Experience utility, and the end user may increase the resolution as high as 5K if desired. This promises to increase visual fidelity without taking a hit in frame rate.

The processor effectively renders 4K resolution in the GPU’s frame buffer, and then applies a Gaussian filter to downsample the image to 1080p when it’s output to the monitor. Finally, a video card with HDMI 2.0, so it can drive a 4K display at a refresh rate of 60Hz.ĭynamic Super Resolution, according to Nvidia, enables the new GPUs to deliver 4K-quality graphics on a 1080p display.
