There is no complex CUDA utilize as it is in Adobe Premiere - in Vegas they are used only to accelerate some plugins that use GPU). GPU encoder is used only to encoding small packs of data comes from CPU render process (that's why on task manager we can observe usage spikes). The best option is AVC/HEVC for source files. The render 4K, 1080p, 720p of 4K or 1080p AVC/HEVC file on timeline, brings always 95% CPU usage during render.Ĭonclusion - render speed by CPU depends on source format of imported video file. Render of the same file but in 4K output format brings up to 90% CPU usage. Render 1080p of 1440p H.264 file on timeline (generated by NVENC from OBS) brings only 50% CPU usage during render. I found that efficiency of CPU depends on codeck of video file imported to the project.ġ. I made some tests and results are interesting. After install studio driver it started working fine. I figure out why NVENC didn't work with 2160p.
