Running the game on a nVidia 250GTS and driver version 196.21. After installing new patch i have glitches in a ground mission, which did not appear in previous versions on this tileset of ground missions.
They appear when chacters use weapons and during explosions.
It would be a nice optical addition: Lights that turn off, when something explodes in the room. Unfortunately those darker squares appear and disappear in fractions of seconds, which is very annoying to look at. (glad that i don't have epilepsy)
