... the problem resides in graphics though , the speed for me reached around 20 but with graphical bugs ... to fix them i can use one of the 2 graphical options :
-Enable decoding of indexed textures
-Disable optimized vertexInfo reading

checking one of them fix graphics but it really drop the fps to around 5.

Similar situation here, but i must add that since r2684 games become friendly with ATI cards (At least with mine) and GOW is one of those games.

The game maximum FPS is 20 and is a decent speed for being playable; however, graphics are very glitch. As fullpulse, it can be fixed enabling the option "Disable optimized vertexInfo reading" but game speed take the price of that fix because FPS goes down dramatically to 1/3. CLUT option does not speed up or down game, neither fix graphics so i keep it off.

Like gid15 told to fullpulse, turning off VertexCache make disappear some strange lines but some glitch graphics will still there; the only option that fix graphics at all is "Disable optimized VertexInfo reading"

To keep game playable on 20 FPS i must have this options enabled:
-Only GE Graphics = Without it game models are just strange bars everywhere.
-Use Vertex Cache = Bring the most important speed boost and can be alone to bring it.
-Use Shaders = Fix some video flaws.
-Disable UBO = Fix some video flaws and bring a speed boost if activated with other speed boost options.
-Enable VAO = Without it game models are just strange bars everywhere.
-Enable saving GE screen to textures instead of memory = Bring a speed boost if activated with other speed boost options.
-Enable Dynamic shader generation = Fix some video flaws and bring a speed boost if activated with other speed boost options.
-Disable optimized VertexInfo reading = This one will fix graphics at least 99% but game speed goes to 2/3 FPS.

So, as i say r2684 changes were magical to my ATI card bringing a very notable and important speed boost to all my games including this one. I guess other improvement like that will make games more friendly with ATI cards . Thanks gid15; keep on.
