Hi 2byts, sorry MoI v4 is not working well on your system. It's most likely some problem with the video driver so it would be a good idea to update to the latest driver to start with.

There are a couple of settings in moi.ini you can try adjusting to see if it makes any difference -

DisplayThreadLimit=1

and

StaticBufferMaxVRAMToUseMB=0

also you can test setting

GraphicsAPI=OpenGL


Another thing is when you go to close it with Task Manager, right click on it and choose "Create dump file" to see if you can get a crash dump file created and then send that to me at moi@moi3d.com , that might help me to get some information on what is happening.
