Maybe we need anoteher with this settings on.

Simple add r_TexturesStreaming=0.
To your autoexec.cfg or system.cfg (or create one)

Done, fixed.

Run #1- DX9 1680x1050 AA=No AA, 32 bit test, Quality: VeryHigh ~~ Overall Average FPS: 43.335

As you can see, performance at VH settings is higher than with HIGH settings before using the command line.


Explanation of what this cvar do.

Quote :

r_TexturesStreaming [0,1,2] - This setting controls the streaming texture system in the game, and if set to 0, textures are not constantly streamed as you walk around, they are preloaded from a cache. While this increases memory usage, and hence may cause additional stuttering on systems with low RAM, for the most part disabling it should cause no problems and will reduce stuttering on most systems. More importantly, disabling it also appears to improve more distant textures without any real drop in performance. You can see an animated comparison by clicking here: Crysis_TexturesStreaming.gif (818KB). As you can see, the distant mountain terrain, especially near the base of the mountain, is much clearer with this setting disabled.
