If driving a Humvee and taking fire in the rear (XD) the impacts hit a good 3 feet behind it, not on the car at all.
When your tactical visor mode's activated, the mini-map's blurred out and there's a second blurry copy of your current objective behind it, along with the one above the mini-map.
The energy/ammo section of the hud often blurrs out when looking at weapons you can pick up or near ammo crates.
Sometimes when running and you power jump you only jump half as high as you should. This is usually when jumping off a ledge, it's like there's 2x gravity.
And if you lose all your suit energy during a power jump for any reason, you'll fall short of the full jump when your momentum SHOULD carry you anyway.
There's no reason that energy should be drained/power mode still on when FALLING from a powerjump or sliding downhill. After the jump energy's not necessary anymore, and it shouldn't take energy to slide. Another issue of momentum, it's not like the suit's doing the work, but gravity is. So you shouldn't lose energy once the action's been done.
From what I've read, alot of people don't notice that the film grain glitch is ALWAYS there and just becomes exacerbated when you continue a saved game or at any random time on certain levels. In bright light, haze, and/or when you tap the button to activate Armor Mode (there's a light flash) you can see what looks like static swimming over everything. The FG glitch is noticed when the diagonal crawling static effect from Nanovision is piled on top of that.
