I tried to use it with Mount and Blade Viking Conquest yet it failed to capture any screenshots. I had to use fraps but fraps often causes freezing.

I've used this program in other games fine but I only play them borderless windowed mode. I'm not sure if it's fullscreen or M&B that is a problem. I'm launching the game via steam and I disabled steam screenshot feature.

Is there a solution to this? Thank you.
