You need to provide far more infos from your system and build
The build is easy zip and add the buildlog
For ufoai add ufoconsole.log and config.cfg ( explorer "%APPDATA%\ufoai" )
your HW driver version and gfx type (ati radeon HD4600)
He is using make_UfoAI_win32.exe
A classic C::B build ....
If we talk about lag, I mean Geoscape
had to disable
"post-processing shader effects" (6fps vs. 45fps)
but i'm using a low^2 gfx card (onboard)
Changing resulotion cap made no difference (1 fps)
