[quote:x9yn9s4h] i noticed that the background blurs and since the game is playing near 60 fps this shouldn't happen, also when if i turn off the camera and i just move my guy around he does get kind of blurry because of the speed.
I could think of several possibilities.
Could you try run your game on other monitor screens? Some of the old monitors render things in such a way that gives you a constant motion blur. Hardware Mouse motion blur, anyone?
OR... this is just biological - an illusion your eyes are perceiving because of the objects are moving at high speed. Since you mentioned the background got blurred when you run at high speed, but the player will be blurred if the camera is turned off, along with mentioning everything blurs in Sonic at high speed but you didn't anything about blurring in SMB, I think this is likely to be the case.
The reason that the background is blurry in both Sonic and your C2 game is because your character is moving so fast (while being centered) that the background goes through from side to side quickly and your eyes couldn't keep up with those quick visual changes. When you disabled your camera, only the character is blurred, because the character is now the one moving quickly on the screen.
The games (Sonic and any C2 games) do not render anything blurry here but because those frames are being rendered at 60 fps and have visual updates moving so fast on the screen that your eyes are playing tricks with you.
Is what am I thinking correct?
