I'm looking for a software that would allow me to post-record videos of gameplay. For example, I'm playing Battlefield 4, I just did some very nice tow, or came across a glitch, I'd like to be able to record it after, so to save to disk the last minute of gameplay. I'm on a budget laptop with i5 6300HQ GTX 950M where performance is an issue, particulary with heavy games such as BF4.
I already tried Nvidia share. The performance impact is quite low, but I recently I have been unable to use it and it requires connecting to their servers for no reasons. It also has a performance impact on startup, I sometimes get desktop not responding because of Nvidia. I also tried Microsoft tool, DVR. The impact on startup seems good, but this severely impact performance while gaming, making the game completely unplayable.
So I'd like to be able to record the last minute with little impact before and after recoring, and also no boot slowdown.
