After some time (default 10 seconds of testing + warmup) the test automatically closes and reports FPS values. Test was developed as part of Metal backend for performance testing and we decided to integrate it with mainline for any potential further development and fixes.

I did basic testing with different options and everything works fine.
Its good that we are open-sourcing this rendering performance test.
LGTM.
