TrueView is an interesting feature that allows first person playing to be just like it would in real life. By enabling different parts of it, you can make rolls, spins, flips, jumps, and knockdowns all feel like you're doing them in real life. Tired of the gun always residing the bottom-right corner of the screen? By turning on TrueView, it's held in first person just like it would be in real life. Ever notice not being able to see your own feet? With TrueView, that will never happen again.
—It can be disorienting, so don't set everything to "Full" right off the bat.
—It will still not allow you to look around corners as well as 3rd Person does. Or at all for the most part.
—Sabering is harder.
—When holding/firing a gun in TrueView, you actually see through parts of the gun. This is due to clipping that occurs - when the camera is close to something, it will show the inside of it. This means that it can be more of a buggy nuisance to play with than a fun addition.
—It can be adjusted by going to Controls > Visual Options.
—Keep in mind that trueview.cfg is simply a file that is written as you change the TrueView settings.
