could you look into your Program Files\Sony\Vanguard\binTest\Caches dir and see if you see 2 files: compiled_PixelShaders.shd and compiled_VertexShaders.shd and let me know what the last modified date is as well as the size of the files?
If they are present but have not been modified recently please delete them and then log into game and play for awhile, check them again when you log out after a session.
