FPS and view range values taken at their apparent best values.

Using smooth lighting, particles enabled, 3d clouds, fancy trees,
connected glass.  All other settings turned off or set to "no"

No mipmap or anisotropic or other filtering was used in any test.

Using Dreambuilder, on my usual test map.
HDX 512px texture pack with normalmaps, total of 5113 texture files

To ensure each test is accurate and records the chosen modes,
Minetest was closed completely after changing settings and then
restarted to measure.

Only the map in front of me and perhaps 30 degrees to each side was ever made
visible.

Screenshot of the area under test, taken with all-view-range turned on only
for the several seconds needed to take it, so one can see ALL of the terrain
that could theoretically appear:

Map was allowed to load and settle for perhaps 30 seconds on each run before
adding the figures to the chart.
