Kurt Kartaltepe, what tooling did you use to find that "All of the cpu usage attributed to Xorg however is actually all kernel time in nvidia_drv.so, if that helps diagnose where this goes wrong for nvidia's driver." ?
I just ran perf while nothing was happening but this bug and from there you can use y our favorite visualization tool (such as flamegraphs) to see 90% of the cpu time was spent in xorg calling into this library.
