I wouldn't had even thought it realistically possible if I hadn't seen the video. Could we please have similar snow FX for ARMA3? This would vastly improve the game for players, map makers and mission creators. And probably wouldn't hurt sales either.
"This video highlights the new procedural snow technology in VBS3. Snow layers are defined using rulesets and rendered at run-time. Snow has depth and affects the simulation of units and vehicles. New fog and snow fall effects are included."
