If you use the same libraries/frameworks in all three you should see nearly identical performance no matter how you write your code (unless you have an application that is heavily dependent on driver performance).For example, dolphin is compiled with msvc on windows and with g++ on linux. That definitely is a significant difference. Of course there's many cases where it won't matter, but there's definitely cases where it *does* matter. Even in my 3-line-test program here I can easily see that virtual function calls are faster in clang++ than in g++, and dynamic_casts are faster in g++ than in clang++. I don't have msvc here for testing, but I'm *absolutely* sure there will also be differences.
Quote:And saying "platform" is not the same thing as saying "OS", as I'm sure you already know the OS is only one part of the platform.I used those two interchangably here, as it was clear from the context that we're only talking about PCs. But we both know what is meant
Quote: Often times direct3d is going to be much faster than openGL even if you spend loads of times optimizing both backendsand often it will be the other way around.
