OK, I just spent a bit of time troubleshooting this 24Hz issue for a buddy of mine that just bought a 46" HDTV for his new monitor. The fix is actually pretty simple, at least if your problem is with a 1920x1080 HDTV. Nvidia's drivers seem to be devoid of any 1920x1080 information, and so any settings you're allowed to use are probably just gleaned from whatever capabilities the HDTV states that it has. If you edit the nv_disp.inf file and add in that your video card is capable of 1920x1080 at 60Hz *only*, then your game should fire up in 60Hz without issue. I can confirm at least that this works just fine for my buddy and his Samsung 46" HDTV, connected via HDMI, using Geforce GTX 280 cards in SLI. For those cards, this is the change I made in nv_disp.inf:

The nv_disp.inf file contains a section titled:

[nv_SoftwareDeviceSettings_GT2x]

And this section deals with settings that pertain to their latest cards. If you have a card older than that, you shouldn't have too much trouble figuring out which section of that file you need to be editing. The file does list all the different cards, and which section applies to those cards, etc. OK, anyway...

Original nv_disp.inf line in that section says:

HKR,, NV_Modes, %REG_MULTI_SZ%, "{*}S 640x480x8,16,32,64 1280x768x8,16,32,64 1280x800x8,16,32,64 1360x768x8,16,32,64 1680x1050x8,16,32,64 1920x1200x8,16,32,64=1;800x600x8,16,32,64 848x480x8,16,32,64 960x600x8,16,32,64 1024x768x8,16,32,64 1152x864x8,16,32,64 1280x960x8,16,32,64 1280x1024x8,16,32,64 1600x1200x8,16,32,64 1920x1440x8,16,32,64 2048x1536x8,16,32,64=3B;"

Edited version:

HKR,, NV_Modes, %REG_MULTI_SZ%, "{*}S 640x480x8,16,32,64 1280x768x8,16,32,64 1280x800x8,16,32,64 1360x768x8,16,32,64 1680x1050x8,16,32,64 1920x1080x8,16,32,64 1920x1200x8,16,32,64=1;800x600x8,16,32,64 848x480x8,16,32,64 960x600x8,16,32,64 1024x768x8,16,32,64 1152x864x8,16,32,64 1280x960x8,16,32,64 1280x1024x8,16,32,64 1600x1200x8,16,32,64 1920x1440x8,16,32,64 2048x1536x8,16,32,64=3B;"

Now, the only change there is that I added "1920x1080x8,16,32,64 " before the 1920x1200 entry. The "=1" at the end of that first section means that those resolutions listed in that section are only available at 60Hz. After making that change to the nv_disp.inf file and reinstalling the drivers, firing up Crysis Warhead then showed 60Hz in the TV's "info" display, whereas it was running at 24Hz before. So, that's fixed for him now, gladly. Now I know what to do whenever I got some extra coin for a monitor like that, heh.
