Yep.

No idea why it happens though, and why only in DX10 for only a few games.

Unfortunately DX10 or 11 doesn't let you set anymore the refresh rate.
You could do that in windows xp, you can't in Vista or 7.
A boneheaded decision if you ask me.

Could this be related to LCDs being so popular?

I mean, for an LCD it doesn't matter what the refresh rate is. For my CRT, I need to adjust the settings on the monitor, depending on res+refresh; settings are different for 1280x960 @85Hz than 1280x960 @60Hz.

When experiencing these overscan issues, my monitor still runs in 85Hz, but it's like the game is rendered (internally?) at improper res/refresh, resulting in incorrect output.

Maybe, I think that Microsoft just said screw the CRT owners and from now on all games that use DX 10/11 will set their refresh rates locked to 60 Hz and thats it. Its part I think of the "consolization" process of computer games. Sad sad sad.

Yeah, seems that way, huh? I still don't understand how those flatscreens took of like they did, guess not too many people are aware of their shortcomings, particularly the early ones.

The current trend is actually to make more and more cheap panels; as long as it's cheap, people buy it. Even the HDTVs are being fitted with TN-panels nowadays. Very few actually look for quality.

Here's how you actually do it without any third party software. I just figured this out after neither refreshlock nor refreshforce nor multires nor powerstrip nor registry editing nor Monitor .INF file patching helped and I was just about to give up.

In contrast, this one works flawlessly on my shiny new GTX 260 (Ain't I sneaky? OK, probably I'm not the first one to figure this out, but no answers on this or other forums suggested this yet.)

Create a custom resolution in your driver control panel. Just make it one line smaller than your desktop resolution - for example 1600x1599, or 1280x1023, or 1280x959, or 1024x767. You get the picture. The point is that you create only one version of this resolution - with your desired refresh rate. And with the timings changed so that to the monitor it looks identical to your desktop refresh rate - just turn the vertical display size down by one and the vertical front porch size up by one. To the monitor this will just look like a black line that happens to be at the botttom of the normal picture.

Then start Crysis and set it to use this resolution. As there is only one version of it, with your desired refresh rate, Windows (and Crysis) has no other choice but to use that one. Boom, 85Hz (or 100Hz or whatever your heart desires).
