I get a lot of tearing in GT5; have since launch.

To be honest it's not that bothersome to me; it's the wiper tearing that is simply off-putting and distracts from the actual racing. I can't stand it.
 
Thats crazy because ever since the update I get no more screen tearing.

I will test these tricks next time I play. I actually play with 240Hz mode to make it more smooth.

Exactly all I have to do is put the Hz at medium and GT5 looks amazing so smooth.
 
I play with the chase cam, with the latest update i dont get tearing in new places,
i just get greater tearing in the same places, that i was getting already.
e.x. elger short at the hairpins that the entire background has to turn almost 180 degrees plus the road turns in to downhill.

Here is my setup if that helps.
-PS: Slim 320GB CECH-25xxB
-TV: Bravia KDL-40W4000
-GT: Display Settings:
--Current Display: 1920x1080 59.94p
--Image Quality: Normal
 
If your HDTV has a 'game mode', I highly suggest using that. Using any kind of "Motion Enhancer" feature (240Hz) actually seems to have the oppposite effect. GT5 and GTA IV for example sometimes become very jittery unless I have my Sony on game mode.

It won't eradicate the screen tear problem, since that's mostly game-to-PS3 processing issues, but it might help make the image more fluid.
 
GT5 never goes beyond 60fps, right? It may drop here and there, and replays are at 30fps. The motion perception with more Hz on the display is just the repetition of frames for smoothing motion, right?

In my Bravia (KDL32cx525, LCD Ccfl), there is a game mode, where it seems to disable most image processing on the TV side, probably to reduce response time. Also, I found a slider to choose between quality or responsiveness of the display, but can't feel any difference.

The tear seems to be mostly related to the PS3 - I'm still unsure how much 120Hz or 240Hz TVs affect it. Maybe we should focus on 720p vs 1080p, Ps3 model, HD space available, video output being used, screen settings in the XMB and in the game.

Which settings change the AA?
 
Sharpen & Flicker reduction affect AA.

TV, PS3 60,120,240hz doesn't matter, it is the Hardware in the PS3 that is under too much load and either drops frames, tears or both.

Putting PS3 in 720p mode is roughly the same because even though there is a reduction in resolution it uses 4xMSAA which uses any benefits that otherwise would be gained!
 
I put all the Games I have on game mode aside from GT5 Game mood seems dark and bland for some reason
 
Screen tear in this game is bad especially on corners with or without other cars. It is especially noticeable on us people with 32 in and above HDTVs.

If the hardware is the only factor to be considered, how can we explain that some people get a lot more tear than others?

Could it be that the PS3 reduces its clock speed when too hot, like some computer GPUs?

Or slims have improved internals than fatties?

I believe that some people just don't notice it as easily as others. I think the way it's described is a little misleading too. The way some people talk you'd think that half the screen freezes while the game carries on for a few minutes on the bottom half.

It depends a lot on the track, as some are worse than others and the same with the camera settings, then the person's sensitivity to it is a factor too. I expect all things being equal the problem is exactly the same for everyone, but we all race certain tracks more in specific cars we like from different cameras, so there is variance in the perception of the problem.
 
Is anyone else getting it really bad around Tsukuba in chase cam? That's the only one i have problems with.
 
It does seem to be worse recently. But that might just be a change in driving habits; I'm doing more races, so there are more cars on screen, whereas before I was just doing practice runs etc.

I will give these extra settings a go, though. I'm using a slim 320, HDMI output to PC LCD monitor at 720p.

You have to tweak the picture setting. Games also have a gamma setting option to help with darkness.

Hmmmm Will Give it a Try I did Find some Custom Settings on the Internet for Improving Game mode for my LG 'Whatever' LCD But not completely Satisfied with them Either To be Honest.

What is screen tear?

In order to combat the issues with reading from while drawing to the same buffer, double buffering, at a minimum, is employed. The idea behind double buffering is that the computer only draws to one buffer (called the "back" buffer) and sends the other buffer (called the "front" buffer) to the screen. After the computer finishes drawing the back buffer, the program doing the drawing does something called a buffer "swap." This swap doesn't move anything: swap only changes the names of the two buffers: the front buffer becomes the back buffer and the back buffer becomes the front buffer.

Computer draws to the back, monitor is sent the front.


After a buffer swap, the software can start drawing to the new back buffer and the computer sends the new front buffer to the monitor until the next buffer swap happens. And all is well. Well, almost all anyway.

In this form of double buffering, a swap can happen anytime. That means that while the computer is sending data to the monitor, the swap can occur. When this happens, the rest of the screen is drawn according to what the new front buffer contains. If the new front buffer is different enough from the old front buffer, a visual artifact known as "tearing" can be seen. This type of problem can be seen often in high framerate FPS games when whipping around a corner as fast as possible. Because of the quick motion, every frame is very different, when a swap happens during drawing the discrepancy is large and can be distracting.
-------------------------------------------------------------------------------------------
When it comes to Gt5 when it takes more than 16.67 ms to draw the new image on the back buffer the front buffer is sent again to the monitor to be redrawn. As the front buffer is redrawn for the second time the buffer are swap thus starting the new image part of the way down the screen. (For example if the new image takes 24ms to draw the tear would be near the middle of the screen) With vsync on this will allow the monitor finish redrawing the image before the swap but will drop the frame rate from 60fps to 30 fps.

I'm not sure if this is the same thing or not because I'm not tech savvy. But after two hours on the 24 hour Nurburgring I just about went mad with how much the screen was jumping around especially in the highspeed corners. In fact it lead to more crashes than I can ever remember doing on that track while my eyes tried to keep track of the car.

Also the car, the longer I went in the race the more it seemed to drift away from center before two or three jumps in the screen.

The sad part is I can't do anything about it until I finish the 24 hours, which at this point I can only stand a couple hours a night as is. :yuck:
 
@montecarlo87 That's is not screen tearing, that is a problem with the new "dynamic" chase cam, it seems to become somewhat detached from the center of the car and jumps from left to right. I am having this same problem doing the Nurburgring 24H race.

As for screen tearing, yeah, its just a PS3 problem. I'm not sure that the system supports any kind of video sync so screen tearing is going to happen on resource intensive games no matter what. One thing that PD could do to reduce load on the PS3 is get rid of those stupid 2D and 2D animated people. Seems it only really happens on tracks where there are hundreds of those buggers all copy and pasted over and over in grand stands, standing and sitting and cheering over and over... It does look very tacky and doesn't make the game or the driving experience any better, if anything it detracts from the experience as they look awful!

As my post pointed out it's not a PS3 problem. Most PC software offer a vsync option. X360 version of F1 2010 had more screen tearing then PS3 version last year when the frame rate drop below 30fps. The reason it wasn't as noticeable was most of the tears were at the top of the screen.

Awesome, thanks for the info. :) Switched to the nose cam until I finish at 5 hours per day. Eyes aren't good enough for cockpit cam ;P
 
Don't know if its considered tearing or not, but when using the behind car view the screen/car keeps 'jumping' every five seconds or so. Quite hard to explain, but its like a few frames were skipped and suddenly the car is in a slightly different place (talking millimeters here) than it was before.

Happens even in a straight line. Will try record it on my fiance's cellphone.

But yeah, am getting a lot of screen tearing still - never had any before the latest update.

Tearing does not depend on display.

Wrong. Tearing depends on the refresh rate of a screen.

My TV has game mode and it makes no difference to the games I play. Also I have 100Hz at maximum on my TV and it does smooth out the gameplay with no jittering as you call it.

I play on both my Samsung LE40A616 40" LCD 100Hz Tv and noticed some tearing with a cheap HDMI 1.1 cable , but as soon as I upgraded to a HDMI 1.4 cable the screen tearing is gone. I also play on my iiYama Prolite B2409HDS 1080P computer monitor 60Hz 2MS response and I have no screen tearing on that.
 
Actually, displaying a 60 Hz source at 100 Hz will cause jitter, because not all frames (in the source) will be displayed for the same length of time, given 100 is not an integer multiple of 60. Whether or not you notice that is another matter.
