Default Re: High CPU usage in X server at 24Hz refresh

I'm still having this problem with the 180.44 driver. To recap, 23.976 fps material in 24 Hz mode (nvidia-settings says 23.97) occasionally plays frames out of order, causing bad stutter. This only happens when vsync is on. Xorg also starts using 100% cpu. I also have a Sony tv, I wonder if it reports bad data causing this problem somehow. Nevertheless, I don't think it should cause this kind of trouble anyway

Nvidia devs, can you please take a look at this? I hate being stuck playing 24 Hz content with the inherently stuttering 60 Hz mode.

Also, I could try 48 Hz, but I have no idea how to make it available in nvidia-settings or if the tv can display it properly. The tv is my secondary monitor via twinview and only the primary monitor appears in the xorg.conf screen section so I don't see where I'm supposed to put the modelines. Not that I know what the modeline should say anyway.

Relevant parts of xorg.conf:

Section "Monitor"
    Identifier     "Monitor0"
    VendorName     "Unknown"
    ModelName      "Samsung SyncMaster"
    HorizSync       30.0 - 110.0
    VertRefresh     50.0 - 160.0
    Option         "DPMS"

Section "Device"
    Identifier     "Device0"
    Driver         "nvidia"
    VendorName     "NVIDIA Corporation"
    BoardName      "GeForce 7900 GT/GTO"
    Option         "NvAGP" "1"
    Option         "NoLogo" "1"

Section "Screen"

# Removed Option "metamodes" "CRT: 1600x1200_85 +1920+0, DFP: 1920x1080_60 +0+0"
    Identifier     "Screen0"
    Device         "Device0"
    Monitor        "Monitor0"
    DefaultDepth    24
    Option         "TwinView" "1"
    Option         "TwinViewXineramaInfoOrder" "CRT-0"
    Option         "metamodes" "CRT: 1600x1200_85 +1920+0, DFP: 1920x1080_60 +0+0; CRT: 1600x1200_85 +0+0, DFP: 1920x1080 +1600+0; CRT: 1600x1200_85 +0+0, DFP: NULL"
    SubSection     "Display"
        Depth       24
