Recording the desktop and high FPS

[BrightCandle]

I have a bug with the NVidia drivers and I would really like to record the effect so I can upload it on youtube, start to send videos etc around the reviewers and get this thing fixed since Nvidia doesn't seem to respond to bug reports normally.

However I really need to record at ideally 144hz, 120hz at the minimum to show up the problem. I also need to record across 2 monitors. So far I have tried:

1) Fraps - can only record the web browser not the desktop and seems limited to 60hz.
2) Dxtory - can't record anything that isn't DX, so nothing on the desktop
3) Bandicam - Can record the desktop and supports 120 hz but none of the protocols it offers can keep up with that many pixels and the record rate in practice is much reduced.

Anyone know of a program that can achieve this sort of recording? Smooth 120hz recording with raw output? I have the disk IO performance (I think) to deal with it but not the performance to compress it on the fly considering the pixels/hz combination I need.

Regardless of the slowdowns, can you still see the effect of the bug using bandicam?

No bandicam adds so many problems of its own that are similar (problems with moving the windows, highlighting text etc). Windows performance problems manifest themselves in particular ways and bandicam seems to impact directly into Windows with its recording mode and is worse than what nvidias drivers are doing.
