I've used Bandicam with usually little impact on the performance of my games, but two have been particularly troublesome when I do record them.
The two games are Alan Wake and Terraria.
I'm able to hit very stable frame rates, but as soon as I hit record the hit 25 and 40 frames respectively. Terraia, although over 30 feels like the whole games has slowed down. I've tried using OBS on those with no issues with performance.
I'm running in an i7-6700 and a GTX 970 with 16GB of RAM.
Any solutions?
