My solution to the problem...

Could you be more specific about "extremely high data rate recording"? We will investigate it further If you let us know how to recreate the issue, your recording target, and your PC specs. Something may reach 800+ Mb/s... An example: (though might not reach the above data rate... should ...

We have tested with AVI, H264(NVIDIA NVENC), and PCM, the "Enable write caching on the disk" option enabled, but we were not able to create the recorded file broken issue.

Test it with extremely high data rate recording. (which would be able to flood the memory buffer)

Bandicam displayed 60fps while recording, first 20 seconds of video were actually 40-55 fps

Caveat:
The game (input source) running at 60 FPS doesn't mean the recording (mainly the encoding) is running at 60 FPS.

2 major bottlenecks: Processing, I/O.

"General" -> "Advanced options" -> "Output" -> "Enable write caching on the disk", tends to break the output (potentially, both the video & audio). Occurred with different codecs (video: NVENC H.264, x264vfw; audio: PCM). BTW according to: Re: caching on t...

Forget to mention, to handle 8K, the 32-bit address space limitation appears to be another obstacle for Bandicam. (currently no Bandicam 64-bit)

NVENC H.264 has a resolution limit of 4096x4096, which made it unfit to handle 8K. Leave alone its missing support for 10-bit. And going to uncompressed solution is apparently not an option (do the math, the bitrate for 8K... SSD arrays? may work), while x264vfw (RGB) has performance issues (x264, o...
