LegallyBlindGame: Here's the issue with the GOG releases using DOSBox. Apparently, Under a Killing Moon does not get along well with it, causing framerate issues that no amount of tinkering with the settings can fix. That is, unless the game originally had choppy and inconsistent framerates when it was released, which makes the game even less appealing.
No problems with DOSbox & UAKM, I'm happy to say...;) I feel as though I constantly repeat this but it is really worth the repeating as people should get as much from these games as possible, I believe...use a *real* DOSbox that's been honed and refined for gaming (and tested out of the Yazoo!): use DOSbox-svn. Only real Dosbox game in town...imo...

latest version is January 2014...and allows you to run the game through D3d output, for instance, and use a variety of gpu shaders which can greatly improve the display & text output even as the resolutions are scaled upwards. DOSbox svn now includes a 64-bit executable (!) that runs *great* with every DOS game I own save *one* so far (which runs fine under the normal 32-bit version of DOSbox.) 64-bit version noticeably improves performance, makes much better use of available ram, etc. DOSbox is so superior to the anemic version of the standard DOSbox Gog ships the difference is fairly dramatic and the configurability of your games is exponentially better...
Next recommendation:
CoolSoftVirtualMidi Synth (for Win7/8)-- I used to use the Gravis Ultrasound emulation with the Tex games that supported it--and any other DOSbox game that supported it--but this GM utility blows GUS emulation away, imo...! It's free (donations only) and it works with pretty much every DOS game that supports GM, and is child's play to setup & use (especially compared to GUS.) Even the soundfonts the developer recommends on the site are free..!
