NVIDIA RTX Video Super Resolution Tested: Image Quality Comparison & Performance In this engaging YouTube video from Gamers Nexus, the focus is on NVIDIA's new RTX Video Super Resolution (VSR) feature. This technology aims to enhance video playback quality, specifically for low-resolution sources like Twitch streams and certain YouTube videos. The primary goal is to upscale 720p footage up to 4K, employing the tensor cores found in RTX GPUs to improve clarity.

Key Insights from the Video:​

• How VSR Works: The technology analyzes low-resolution videos and uses a deep learning algorithm to predict and upscale the image to a higher resolution, attempting to reduce compression artifacts and sharpen edges. This means that while watching low-bitrate streams, users might experience a clearer and more defined picture without needing a higher resolution source.
• Testing Methodology: The video presents a series of comparisons between VSR enabled and disabled, using various footage types. Multiple tests are conducted across resolutions—from 720p to 4K—to gauge the effectiveness of VSR in enhancing video quality.
• Performance in Action: Initially, the results showcased that VSR significantly improved the legibility and overall appearance of text and edges in 720p footage. However, as the resolution increased, the differences became subtler, particularly in fast-motion scenes where the benefits became less pronounced.
• Limitations and Caveats: The presenter notes that VSR exhibits varying results based on conditions such as internet bandwidth and the inherent quality of the original video. While it’s understood that this feature may excel in lower quality streams, its effectiveness diminishes with higher quality sources and fast-moving content, often leading to more noise or distortion.
• Browser Compatibility: Currently, VSR is only functional in Chromium-based browsers like Chrome and Edge, which could limit its accessibility for users on other platforms, such as Firefox.
  

  Conclusion​

  Overall, NVIDIA's RTX Video Super Resolution shows promise, especially for those with lower internet bandwidth seeking a better viewing experience. The potential for improvement is significant as the technology develops, much like DLSS did for gaming.
  

  Discussion Points:​

  • Have you tried VSR yet? What differences did you notice in video quality?
  • Are you satisfied with video quality while streaming, or do you often encounter issues with lower bitrates?
  • How do you feel about NVIDIA's approach to enhancing video playback as opposed to gaming?
