(This is copy of my forum thread, located here, but now on the AnswerHub for support).
We’re spawning in a few thousand basic cubes at runtime, and have fantastic performance running a DebugGame build out of Visual Studio (with a debugger attached, no less!), but running the “Test” build configuration (both Win32 and Win64), which is like a shipped build but with profiling enabled, we get horrible render performance - fps: 200 vs ~20.
Why is there such terrible performance in what should be the superior build configuration? The render thread and GPU are getting totally hammered!
Thanks!
