With many great effects and shaders at your disposal, one of the biggest risks is overloading a scene with too many effects and slowing down the frame rate in the process. Most shaders and effects in CryENGINE are fast and optimized. These can be used without much performance impact. However, when too many effects are used in a scene, the frame rate might be impacted considerably. During game development, often so-called beautification passes are done to a level or environment. During those passes, a lot of eye candy and polish is added. It is important that during those beautification tasks, the performance and frame rate are closely monitored to catch any performance impacts early on.
Luckily, CryENGINE provides a powerful set of profiling tools that will help you identify performance bottlenecks easily.
