Does NVENC encoding affect FPS?
As you can see, NVENC has the least impact on performance at 60 FPS output. When using x264 encoding, the test system was not able to play the game faster smoothly from the preset on. FPS minimum values of less than 30 have a negative effect on the gaming experience, as movements are perceived as stuttering.
How do I change the encoding on NVENC?
How to Enable Hardware Encoding (NVENC) in OBS
- Overview. The benefit of hardware encoding is that it reduces the load on your CPU by using a purpose built piece of hardware on your Nvidia graphics card.
- Go to settings. Go to ‘settings’, then select ‘output’ from the side menu.
- Enable hardware encoding.
- Done!
Does NVENC affect CPU?
Like I mentioned before, the advantage of other encoders like NVENC is that they use a dedicated chip on the GPU to take the pressure off your CPU. The less work your CPU has to do, the better your games will run and the less likely you are to drop frames while streaming.
What CQ level should I use?
When switching to CQP the bitrate control is removed and replaced with CQ Level from 0 to 30. The lower the number, the higher the quality, but if you’re recording at anything less than CQ Level 14 you’re probably wasting your time as it’s essentially lossless video at that point.
Is CPU or GPU more important for streaming?
While the CPU is important for the streaming aspect, the GPU required for a streaming build can be very variable depending on personal preference. These cards can handle games like Overwatch and Destiny 2, but you will need to turn some settings down and sacrifice a few frames in you stream output.
How big is a NVENC HEVC input file?
Using the library libx265 I am getting about 85fps when working on a file that is 720p, but if I use the nvenc_hevc I get around 600-700fps My input file is 269M and when I use the nvenc_hevc it grows to 394M.
Are there any issues with the file size of NVENC?
The only issue that I am experiencing is file size. Currently, an NVEnc-encoded file is nearly double the size of the same file that is encoded via CPU. I did a search here in the issues and do not see this discussed anywhere.
Are there any NVENC encoders for handbrake?
HandBrake also includes support for AMD VCE, Intel QSV, and Nvidia NVENC hardware encoders. These encoders produce H.264 and/or H.265 video at extremely high speed, at the expense of some quality and larger file sizes. Hopefully, it will assist anyone else running into this issue.
Why is NVENC _ HVEC faster than libx265?
My understanding is that the difference between libx265 and nvenc_hvec is not the algorithm that is used to do the compression, but that it utilizes the GPU to accelerate processing. With that understanding the resulting file sizes would be identical regardless of which I used, just the nvenc_hvec would be faster. Is that a faulty assumption?
