Hey,
I'm not able to capture in ARK: Survival Evolved anymore after the last update of Dxtory.
It some to be a conflict with the Battleye (Anti-Cheat) client.
As soon as I press the capture key, the Battleye client creates an error / info message:
Try selecting a 32-bit codec version. Ark's Battleye doesn't play nice with 64-bit codecs last time I tried.
Also, this is an issue between Battleye and the codec (UTvideo), not Dxtory. There's a good chance that UTvideo did an update and Battleye does not recognize it and flags it as suspicious, resulting in a game crash.
