It needs more bitrate for the same quality of footage. NVENC is up to 10% "worse" in image quality, according to VMAF.Note: Somehow upscaled 720p to 1080p at the same bitrate - according to VMAF - can have better perceived image quality? I'm trying to understand why this is the case.See my previous guide on Bits per Pixels. Note: 720p footage encoded at the same bitrate as 1080p footage will look cleaner, because of the amount of Bits per Pixel available to encode.Note: Medium to Slow paced games can be fine, i.e: PC Builder and Swag and Sourcery look great according to VMAF.1080p 60 for fast paced games will not have enough bitrate and will have image quality loss.At stock profiles: going l ower than x264 FASTER generally yields diminishing returns (see results).**Note: I tested with a 1080Ti, a Pascal NVENC card.*Note: This only goes for RTX TURING NVENC, Older gen cards will be slower.x264 is still superior in image quality, though NVENC* is lighter to use and is making progress to match x264. ![]() More game(s), let me know which in the commentsĪdd tuning results on x264 FASTER with custom x264 flags vs stock FASTER/MEDIUM profiles If you guys want a certain game tested, please leave a comment and i'll see what i can do.Īpex, Forza, Doom, Swag and Sorcery, PC Builder Simulator.Īdd Doom NVENC data. I'm still in progress of adding more data/games, and this is a preliminary version. This is where encoding comes in.Īll the result data is available in this google sheet. A "visually lossless" video can easily have a 30-50mbit bitrate, but not everyone has that amount of bandwidth, let alone processing ability to watch, encode and live upstream it. Idealy we'd like to send a high quality stream of data, but bandwidth and processing power becomes an issue at the receivers end (i.e: Twitch, Mixer, Youtube). Getting the world to see our gameplay requires us to capture it, pack it and send it to our platform of choice. The x264 SLOW king is dead, long live the x264 FASTER king.
