Huehuecoyotl: I've been trying to get Overseer to run on my laptop for a few hours now with no progress. The problem is that the screen remains blacked out after opening the game unless I alt-tab out and back in, in which case I can see the main menu screen but the mouse icon doesn't appear to move until I alt-tab back in again. The mouse itself does move, as I can (invisibly) position it over something and click and will find that the movement/click has registered when I alt-tab back into the game, and the sound seems to be working just fine.

Overseer is set to run as administrator by default, and I installed the game in C:\Games to avoid the issues with Program Files. I've tried redownloading and reinstalling, experimenting with various compatibility settings, switching the "Threaded optimization" option in the Nvidia Control Panel to "Off" and "Multi-display/mixed-GPU acceleration" to "Single display performance mode", adding "/affinity 1" to the target for the game's shortcut, and changing the laptop's energy management settings, all to no apparent effect.

All of the solutions I could find to this problem were for ATI cards. They seemed to suggest that the problem was running the game on multiple cores, but as far as I can tell it should be running on only one with the settings mentioned above.

My system:

Windows 7 Home Premium 64bit
6GB RAM
Intel Core i3-2330M @ 2.20 GHz
NVIDIA GeForce GT 520M
(It's also got an integrated Intel chip, but the first thing I did upon encountering the problem was to switch to the Nvidia.)

Huehuecoyotl: It starts, but nothing shows up on the screen. I can hear the audio from the opening movie/logos/whatever plays before you reach the main menu, but I can't see them. And as mentioned above, when it gets to the main menu I can alt-tab out and back to see it, but the mouse icon doesn't appear to register any mouse movements unless I alt-tab out and back again, in which case the icon will have moved in a manner consistent with any movements you made before switching windows. I also I have to alt-tab to another window and back for any change to register on my screen if, for example, I click "New Game" or "Config".

Basically, the game seems to be working just fine except that the graphics freeze on whatever frame it's displaying when you open the window and can only be "refreshed" by switching to a different window and back.

plumgas: install the new ffdshow maybe thats your problem https://dl.dropboxusercontent.com/u/21372568/ffdshow_rev4500_20130106.exe
this may or may not make a difference.

WRMW: I have the identical issue. I've tried all the listed solution I've seen online (including downloading the new ffshow) but nothing has worked.

Huehuecoyotl: Still having the same problem after installing it. Thanks for the suggestion, though.

waltc: Have you installed the June 2010 version of Microsoft's DirectX? That was the last version of D3d 9.0c that Microsoft shipped and is more compatible with older games than the Dx10/11 that ships with Win7.

I have a desktop with an ATi gpu and the game runs almost perfectly under Win8.1 & now even Win10TP. The earlier DX versions install alongside the newer versions without overwriting them, so you still retian DX10/11 D3d support.
