My glitches are good compared to what others have faced. It's just a poor port.
It definitely has some glitches, but the gameplay improvements that they brought over from Crysis 2 make it superior to the original pc version, in my opinion at least.
I didn't realize some of the changes made to the game because I never played the PC version. It seems that in some ways, the graphics are better on the 360 than on the PC (running at the same resolution) like the lighting and better quality textures.
