![]() Fix #4 Check privacy control configurationĬheck the privacy configuration and edit the setup of NVIDIA Geforce Experience if ShadowPlay fails to record the proper monitor. Although it may sound like conventional customer service advice, it does work on occasion, and it is such a simple remedy that it is worth a go. Plug the monitor cables back in once it’s turned back on, and it should work. It is the simplest solution to the problem of incorrect monitor recording with ShadowPlay. Simply unplug your primary monitor display cable and second monitor display cable and then restart your computer. Fix desktop capture NVIDIA ShadowPlay recording wrong monitorįix #3 Unplug and replug monitor and restart computer The bitrate can be manually adjusted, and the available ranges are determined by the user’s screen resolution. After capturing a frame, ShadowPlay encodes it with a dedicated GPU hardware accelerated H.264 video encoder that can record up to 4K resolution at 130 Mbit/s with minimum performance impact on the rest of the system. Instead of capturing the entire framebuffer, NVIFR lets you capture a single window. Frame Buffer Capture (NVFBC) and Inband Frame Readback are two capture methods ShadowPlay can use (NVIFR). Any Nvidia GTX 600 series card or higher is compatible with ShadowPlay. It was released in 2013 and can be set up to record a continuous buffer, allowing the user to store video in the past. NVIDIA ShadowPlay is a hardware-accelerated screen recording utility included with Nvidia’s GeForce Experience program for GeForce GPUs. To fix the Shadowplay recording wrong monitor issue, several troubleshooting steps will be required. Do you have Multiple displays and have ShadowPlay recording wrong monitor issues? It could be an issue with the GeForce Experience software, display settings or monitor settings, incorrectly positioned monitors, or privacy control configuration, just to name a few. To patch patch both libnvidia-encode and -fbc, unless nvidia massively changes their drivers, so far it has worked on each driver release.

Sounds like a great project, that could be helpful for those of you who want high-performance recordings or something more like Nvidia ShadowPlay perhaps. They have a lot of plans for it including support for AMD and Intel GPUs, the ability to dynamically change bitrate / resolution to match desired fps, see the cursor in the recording and more. This of course highly depends on your CPU but the point here, is that it uses the full power of your GPU, and seeing a performance loss with OBS on Linux is pretty common. In their own testing, they said they saw FPS drops from 30 to 7 with OBS Studio at 4K but with their tool they saw a solid 30FPS. This means that CPU usage remains at around 0% when using this screen recorder. This gpu-screen-recorder keeps the window image on the GPU and sends it directly to the video encoding unit on the GPU by using CUDA. OBS only uses the GPU efficiently on Windows 10 and Nvidia. These operations are very slow and causes all of the fps drops when using OBS. OBS only uses the gpu for video encoding, but the window image that is encoded is sent from the GPU to the CPU and then back to the GPU. Why make it? Well, in their own words on how it's different to OBS when paired with NVENC: They claim it's the "fastest screen recording tool for Linux". It doesn't have a fancy name, just called " gpu screen recorder" along with GTK front-end you can use to help manage it. Find you get too much of a performance hit using other recording tools like OBS Studio? Maybe this new tool will help.
