Hello, I just built a new computer today and downloaded bandicam. The fps while I play games hovers around 144 fps but when I hit record in DirectX/OpenGL mode, it drops down to 10 fps, which I don't understand why. I tried different codecs, like MPEG-1, NVENC, and lagarith lossless codec and all give me the same results. Here is the spec of the system I am using.

Motherboard: MSI X99S Gaming 7
CPU: Intel i7 5820K 3.3 Ghz
GPU: EVGA GTX 980 Ti SC ACX 2.0
RAM: G.Skill Ripjaw 4 DDR4 16GB 2400mhz

I would appreciate for help.
