http://youtu.be/-zd1Ascm-9A My configuration: E8500 processor, 4 Gigabytes of random access memory, EVGA GeForce GTX 650 Ti BOOST Superclocked. Than it can be caused image twitchings? Sorry for wrong English.
To be more exact, the fact that it's dual cores. Crysis 3 hates dual core CPUs and though the E8500 is fast, a weaker quad core CPU will run the game better.
