- [Resizable-BAR](https://game.intel.com/story/intel-arc-graphics-resizable-bar/) is not mandatory for hardware acceleration, but it can affect the graphics performance. It's recommended to enable the Resizable-BAR if the processor, motherboard and BIOS support it.
- [Resizable-BAR](https://www.intel.com/content/www/us/en/support/articles/000090831/graphics.html) is only mandatory for hardware acceleration on ARC **B-series** cards, or the media driver will crash the transcoder. For ARC **A-series** cards, the media driver can tolerate not having it enabled but it's also recommended to enable Resizable-BAR if the processor, motherboard and BIOS support it, to achieve the best performance.
- [ASPM](https://www.intel.com/content/www/us/en/support/articles/000092564/graphics.html) should be enabled in the BIOS if supported. This greatly reduces the idle power consumption of the ARC GPU.

13. Intel Compute-Runtime versions starting at 25.18.33578.6 are broken for certain GPUs. The issue has been verified on Arc A series GPUs. If you are using one of the effected models it will be necessary to install the latest known working version of 25.13.33276.16 until the [issue](https://github.com/intel/compute-runtime/issues/831) is fixed. This can effect containers as well, if you are not using the [official image](https://hub.docker.com/r/jellyfin/jellyfin), check your version in container as well.

1. Consumer targeted [Geforce and some entry-level Quadro](https://developer.nvidia.com/video-encode-and-decode-gpu-support-matrix-new) cards have an artificial limit on the number of concurrent NVENC encoding sessions. This restriction can be circumvented by applying an [unofficial patch](https://github.com/keylase/nvidia-patch) to the NVIDIA Linux and Windows driver.
