How to run game without textures?

I want to run my project without textures and see how map looks like and do some profiling/check statistics.
I can do this in Editor, but I need to do this in real time.

maybe you can press F4 when you run the game

This does not affect statistics. It looks like textures are still in memory. I’m searching for solution to disable textures and don’t load them in memory to check performance.
