Below are some tips to help you get the most out of MixEmergency 3 and its new GPU-accelerated video decoding of H.264 videos (on compatible hardware).
To take advantage of the GPU-accelerated video decoding you need to ensure:
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.
In the Advanced Preferences of MixEmergency, ensure that the preference "Enable GPU-Accelerated Video Decoding" is enabled (this is enabled by default).
It's also important to set the Cache size to a level suitable for your GPU. It is recommended that you set this lower than half of the available RAM of your GPU (closer to a quarter is better). For example, if using an Intel HD Graphics 4000 (1024 MB) GPU, it is recommended that you set the Cache size to between 200 to 300 MBs.
Here are a few other tips to help you optimise the use of your computer's CPU and GPU:
