Motion Blur

Java 2D
#1

Hey guys, I’m doing a pong game in full screen as some practise.

The problem is that when I move the paddle (or anything) more than about 8 pixels a sec I get a motion blur. I was wondering does this happen all the time? Is it a form of screen-tearing? It’s just kinda annoying that the paddle goes sorta blurry when moving any way fast. Do I just have to put up with it?

I don’t think I need to post code because it’s more of a general question, but if ye’s need to see it I will.

Thanks a lot,
Jim.

Are you using a slow TFT?

sorry, what does TFT stand for?

its a type of Flat Screen (pc monitor). Screens of that type if they have a high refresh rate it will cause bluring, however anything below 16ms should be fine for games, anything above might cause ghosting and bluring.

Well, you can also get that kind of effect with CRTs.

TFTs need some time to switch and CRTs use some phosphor layer for making the image steady… the older the CRT is the longer it glows. With TFTs the effect is generally stronger.

hey yea it must be that, I’m on a 6 month old dell laptop (top of the line at the time). It’s widescreen LCD. Thanks for the info guys.
