God of War 3 BCES00510 Major graphical bug

I was playing the game no problem up until the point where you fight water horse after ''Tomb of Ares'' save point. There starts a major graphical bug which in background there are copies of the boss. And after the boss fight where you need to jump into Gaia, screen starts to rotate endlessly and you cant do anything which makes the game unplayable.

When i arrive at that part i always get this error: E RSX: set_memory_flags(0xc0384000, 0xc0707fff, 1): region_ptr == nullptr
E RSX: Format incompatibility detected, reporting failure to force data copy (VK_FORMAT=0x2C, GCM_FORMAT=0x9F)
