Got in the mood for some tactical goodness and didn't feel like playing ET or Jagged Alliance 2, so I decided to give Aftermath another chance (at the very least, it is a damned fine SG-1 game :p)
Unfortunately, the startup movies are very choppy and I suspect the gameplay would be as well (haven't tested that yet).
I suspect I already know the problem: It is trying to run at 75 Hz while my monitor is 60 Hz. Unfortunately, I can't change this because whenever I try to test the settings in the configuration program (which seems to be required to save the settings, the program crashes with the following
Application crashed: access violation reading from address 0x0000000c!
SymInit search path: C:\Program Files (x86)\GOG.com\UFO Aftermath
SymGetSymFromAddr:487, addr:0x004194f0
(...)
StackWalk:6
the (...) are a few more lines of the SymGetSym crap which I am sure is useless for almost everyone :p
Any tips? I tried to find the settings manually, but I can't find any files in the install directory that reference refresh rate or resolution.
And I am running Win7 64-bits.
Thanks.

Thanks. I have Catalyst but I was in "standard view" and the Vertical refresh wasn't an option. I had to set Catalyst to "advanced view" under preferences to see the refresh options. Problem solved!! I can see the movies now...it added some graphics glitches to the menu screen but doesn't seem to have messed up anything else.

I have the same problem. Tried changing VSync in CCC, didn't help. Changed the config file with KEY "video_mode" INT 88, now the game runs part-screen (1024x768 out of my 1360x768 monitor), and the movies run a little faster, but are still very choppy and slow... Any way to make it run full-screen (even if "stretched") and make the videos in the game run at their normal speed?

Thanks @burigufutsushide
Vertical Refresh worked wonders. Now i can view the Videos. :)
