Strong computer requirements, I have:
Model Name: MacBook Pro
Model Identifier: MacBookPro15,2
Processor Name: Quad-Core Intel Core i5
Processor Speed: 2,3 GHz
Number of Processors: 1
Total Number of Cores: 4
L2 Cache (per Core): 256 KB
L3 Cache: 6 MB
Hyper-Threading Technology: Enabled
Memory: 16 GB
And some scenes get slower and slower, dialogues for example the sound goes faster than the subtitles, and playability gets also affected.
Maybe it will help if there is an option to chose an smaller resolution.
