For TikTok Live (vertical, mobile-first), NVENC (GPU) is superior to x264 (CPU) for 99% of single-PC streamers. The visual quality difference at TikTok's bitrate cap is invisible, but the performance cost of x264 is massive.
Crisp at start, blurry minutes later? This guide deep dives into "adaptive bitrate" mechanisms, providing 10-minute fixes from hardware encoding optimization to network jitter troubleshooting.
