The main source of dissatisfaction was the extremely slow video processing in the Topaz app using ffmpeg libraries when exporting in H.265 format with a bitrate of 40 Mbps. Scaling a seven-minute video from 1080p took over 30 minutes, and generating a short 15-second preview fragment took about a minute. During rendering, CPU load remained at 80%, while the flagship GPU did not show the expected speed boost. The owner questioned the wisdom of such an expensive purchase given the constantly rising cost of components.

In the comments, community members pointed out potential errors in the system's setup and benchmarking. Users noted that upscaling content from a relatively low 1080p resolution is limited by the CPU's processing power, leaving the GeForce RTX 5080's full potential untapped. Commenters also highlighted the peculiarities of hardware acceleration in ffmpeg-based utilities, as well as the use of a budget MSI B840 VC WiFi motherboard, which can limit the processor's peak power consumption at the hardware level.
