Not many days go by that I don't fall in love with Far Cry 2 just a little bit more. Now I already knew it was a great graphics engine, but it takes one hell of a graphics engine to do this (you can skip the first 38 seconds of the dude admiring his level):

I've seen plenty of fancy fireworks in the course of normal gameplay, but it's pretty amazing to see just how much the engine can handle. The level was created with the map editor on the PC version. The guy who made it is using a pretty beefy system (3.5Ghz Athlon processor, 3GBs of RAM, a Radeon HD 4850 videocard), but note how there's virtually no slowdown during all those pyrotechnics. And look how far up the debris are thrown during the bigger explosions.

Thanks Blue's News!
