Torchlight

Native.
Select your resolution from the in-game options drop-down menu. (Settings are saved in C:\Documents and Settings\<username>\Application Data\runic games\torchlight\settings.txt)
A note on 'Netbook mode' : this checkbox is merely a quick "low-end settings" switch, it has no incidence on widescreen support. In "non-Netbook" mode, netbook resolutions such as 1024x600 are supported just the same.

All HUD, menus and UI elements scale correctly to the sides of the display.

16:10, 15:9, 16:9 + netbook and Surround resolutions are natively supported with Hor+ gameplay.

Note: When entering a new map or gaining a level, there's a one-second message displayed on top of the screen. These brief messages stretch. Refer to additional screenshots.
