Crysis, the DX10 is a lie?

These screenshots were taken on Windows XP computers, with enabled features that were supposedly exclusive for DX10. What does it mean?

Essentially, what the tweak does is allow DX9 users to use the "Very High" settings that are exclusively reserved for DX10 users.

The tweaks are relatively simple. Users need to edit all of the files found in "\Crysis SP Demo\Game\Config\CVarGroups". First, back up the folder. (Since they're all text-based config files, the backup is just a few megabytes, if that.) You'll then need to edit each file, taking the first block of text and swapping it out with the text with the third option. In the example (sys_spec_Particles.cfg)below, take the text at the bottom (in italics) and replace it with the text at the top (in bold).

[default]
; default of this CVarGroup
= 4
e_particles_quality=4
e_particles_lod=1
e_particles_max_emitter_draw_screen=32
r_UseSoftParticles=1
e_water_ocean_soft_particles= 1
e_particles_object_collisions=1

[1]
e_particles_quality=1
e_particles_lod=0.75
e_particles_max_emitter_draw_screen=4
r_UseSoftParticles=0
e_water_ocean_soft_particles=0
e_particles_object_collisions=0

[2]
e_particles_quality=2
e_particles_max_emitter_draw_screen=8

[3]
e_particles_quality=3
e_particles_max_emitter_draw_screen=16

Now, enter the game, and under the "advanced" graphics settings, turn up all of your settings to high. (Your system will still show the "high" settings enabled, even though the new eye candy is turned on.) After you've seen what the game looks like at its best, feel free to decrease some of the settings to improve performance.
