Unreal Performance Tests

>>>>> PERFORMANCE TESTING for Unreal Migration from 5.4.3 (old) to 5.7.4 (new) <<<<<<

1280x720 windowed mode, all settings to EPIC

Numbers are FPS

Note: on Mac I had to upgrade XCode from 15.4 (used by the old release) to 16.2 (used by the new release).

Note: On a PC, textures and render targets live in the GPU's dedicated VRAM, Apple Silicon uses Unified Memory - CPU and GPU share one physical pool. So on the Mac, that same ~5 GB of textures/render targets shows up in the process footprint and counts against the RAM you see with 'top'.

Windows: old: 46-47  new: 65 (memory used: old: 1.34Gb new: 1.639Gb)

Mac: old: 9.5 new: 2.5!! (memory used: old: 3.381Gb new: 7.375Gb) Here we are trashing memory to swap, as we go above about 1.5Gb of the physical memory. In a case where it was not swapping we got 19FPS.
