Just thought I would post about the major FPS drop when using the latest Bandicam (V 1.7.2) in Bad Company 2 (Steam). The drop is anywhere between 20 - 50 FPS which is something that Fraps would do. On the game I average between 80 - 100 FPS and when I record, it drops to around 40+ FPS which I assume is a flaw/bug in the code somewhere.
These are the settings I use to record:
The game runs through Steam which I suspect could be the problem here but Modern Warfare 2 and Bandicam run quiet nicely together. I will add that Bad Company 2 is Direct X 11, again could be an issue with Bandicams compatibility with Direct X 11 games, especially Bad Company 2.
