Final Fantasy Type-0

So, I specifically checked. In the demo, in a fairly normal area, on my desktop:

1x render / no texture scaling: 282 MB VRAM (may be other apps, let's call this baseline.)
7x render / no texture scaling: 423 MB VRAM
10x render / no texture scaling: ~480 MB VRAM, unplayably slow
1x render / 3x texture scaling: 321 MB VRAM
1x render / 4x texture scaling 386 MB VRAM
7x render / 4x texture scaling 495 MB VRAM, still playable

Not super scientific numbers, but my point is just that both render resolution and texture scaling cost GPU memory. Also, both are exponential. 10x render resolution requires 100 times as much memory for render buffers. 5x texture scaling requires 25 times as much memory for textures (actually possibly more because scaling requires 16-bit textures to be converted to 32-bit, which doubles the memory requirement as a baseline.) Keep that in mind when choosing your quality settings.

Also, texture scaling will slow down every time a new texture is used and must be scaled, of course, but that's outside of sheer memory usage.
