Hi t0msk, welcome to Unreal Engine! 
Yes, of course there is: Timing Insights in Unreal Engine 5 | Unreal Engine 5.2 Documentation
And for GPU: Timing Insights in Unreal Engine 5 | Unreal Engine 5.2 Documentation
There is also an option to get memory statistics: Stat Commands in Unreal Engine | Unreal Engine 5.2 Documentation
Press “~” key to open the console for running console commands (you may need to rebind the hotkey on German keyboards for example.)
I didn’t find anything about VRAM allocations. But if you mean the VRAM size of the screen, that’s widthheight4*4 bytes, if that is really important to you
I hope I was able to help!
