I and some good friends of mine decided to try making a smaller game in C++ just for fun, with help of DirectX and some other libraries original written in C++. I would say all of us have experience from earlier development projects but however almost only from managed languages. I have been programming in C++ before but never any bigger projects or solutions.
When we did a bit of research we found that it seems like a lot of people worries about memory fragmentation on the heap when creating small short lived objects frequently or when the memory usage grows. We got a bit concerned that we may have to take this under consideration when designing the game engine, instead of just creating objects the C# or Java way with "new". (I'm aware of that you must free the memory unlike in the managed languages mentioned)
Is this something you should worry about and if so what are our options? I have read a bit about memory pools, but will we need one and is there any known already working we could use if so? We are very thankful for all feedback we get on this.
