Is the info window bit where it shows if it's using the GPU still working? I found this below in the "optimization" section but can't see it on my system. I'm on latest version and can't see decoding method You can check whether GPU-acceleration is being used for a video by opening the Info window of MixEmergency. This will list either "CPU", "GPU / Hap", or "GPU / H.264" as the method of decoding. Note that this will only change when a video is loaded, so if you disable GPU-accelerated video decoding, you will need to reload the video before the setting will take effect.
