This seems like overkill, and unless it has a Shadowplay-like mode where you're persistently recording and can just dump the last few minutes to the hard drive, I don't think I'd even know (or remember) when to hit record. (So actually, maybe just use Shadowplay instead?)

One other alternative is Idea/Rider's Local History feature which is basically a parallel repo of your entire project that automatically saves a snapshot of your changes every time you save a file. Super useful for all kinds of backtracking, and you don't even need to remember to use it until you actually need it.
