We will still need to gather tests for the following backends: Quite the improvement from 55fps I’m sure you’ll agree. NOTE: The above is long since out of date – the same video is now 256fps with hardware decoding and 224fps with threaded video decoding at an automatically defined amount of threads. Our CPU load averages around 11% with GPU load averaging around 20%. With hardware decoding (the 2080 Ti defaults to DXVA2 for this test) – we averaged 77fps with the 2080 Ti. Our CPU load averages around 15% with GPU load averaging around 11%. With software decoding (the current default in RetroArch) – we averaged around 55fps with the 2080 Ti. With such a CPU, we don’t really have a CPU bottleneck and we are merely GPU bound when it comes to rendering the content. The CPU we’re using for this test is an Intel Core i7 7700k. This means that if your CPU is not up to the task, you won’t be able to run this content at fullspeed.Īs a stress test video, we picked a 4K video (3840×2160) with a total bitrate of 29561 kb/s (h264/AVC1, YUV420P), running at 30 frames per second. 1440p and 4K content therefore falls back to software video decoding.

It only supports 1080p hardware video decoding at best. – This is a slightly older card from 2014. – Can hardware decode 1080p/1440p/4K content. We have performed the following tests so far: VDPAU (Tested on an AMD System with VDPAU to VAAPI layer).

This so happens to be the case on many ARM SoC devices out there, such as the Raspberry Pi and Odroids. This meant that on some systems, video playback could be too slow if the CPU was too underpowered. This means that the CPU has to do all the decoding instead of being able to delegate it to the GPU. Up until now, all video decoding was performed entirely in software. Just like VLC, Kodi, mpv and other video players out there, it accomplishes this by leveraging the ffmpeg project. As you may well know, RetroArch has embedded video player support on platforms such as Windows, and Linux.
