I've been doing a lot of research on the topic, and it seems to be that it's more of a limitation of X than anything else. I can't believe that what I'm after is so far-fetched. I'm not not looking to record a game or anything - just the desktop. I have an Nvidia GPU, so on Windows I can use Shadowplay which uses the GPU's onboard hardware h.264 encoder to get perfect 60FPS recording. It did slightly better, at around ~25-30FPS, but it is only able to record OpenGL applications, so it can't record the desktop. I tried a few other software applications, and none of them was able to produce a solid 60FPS recording.Īs a last ditch effort, I spent an hour compiling some program from 2013 from source that is supposedly able to capture directly from the OpenGL framebuffer.

However, if I even so much as drag a window, the recording drops to ~15FPS. It records at 60FPS if the screen is idle. For several weeks now, I have been trying to find a solution to record my desktop at a solid 60FPS, and I have completely failed in my endeavor.
