Currently, we're finalizing trees and bushes for ARMA2. The biggest problem with vegetation is impact on game performance, so we develop a lot of new techniques on the side of the engine and on the side of LindaStudio as well. We make very deep analysis of performance problems in Armed assault and we find, that the main problem is overdraw in the first 20 meters of the scene. So it means, we needed to optimize the overall surface of trees and bushes and develop some more effective shaders and drawing techniques in the engine to reduce these aspects. So what did we do?
