By Default, Crysis can not be played on very high settings on Windows XP due to DX 9, but a small hack can let you change it. This hack allows you to tweak some of the CVarGroups folders in Crysis and achieve very high settings in Windows XP using DX9.
I found a couple of Tweaks at Crysis Forums, which worked for many people. You get the whole deal: Motion blur, Depth of field, the so-called god-rays, every single “dx10 only” effect is active and running perfectly on DX9 Windows XP.
How to configure very high settings for Crysis using DX9 and Windows XP
Suggestion 1:
Suppose you tweak the configuration files in CVarGroups by copying and pasting the “very high” settings (1st paragraph) IN PLACE of the “high” settings (last paragraph). In that case, the game will load the highest possible settings even though the drop-down menus display “high.”
Suggestion 2:
- Try this only if Suggestion 1 does not work.
- Make a copy of your CVarGroups in case you mess up things.
- Now open the “sys_spec_Particles.cfg”.
- Copy the default (4) option, which is the first block of text, and paste/replace the last block of text with it.
- Do this with all the configuration files in the CvarGroups folder.
Original [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 Copy all the red text and paste/replace the blue text with it so it looks like… Edited [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=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
This tweak is taken from Crysis forums and has been tested by one of my friends. He said it worked surprisingly well. Since DX10 is not available for XP, achieving this high configuration is not possible, but with this, it’s straight on the face of Vista. Probably Microsoft does not allow it when it’s not DX10, but this tweak works like magic. Thanks to guys at Crysis forums and a Guy Sandman who referred this link to us.
