hi guys got a pc about 3-4 months ago from OCUK

it was ... a titan vulcan
II X3 Tri Core 720 2.8GHz @ 3.3GHz
-Gigabyte GA-MA790XT-UD4P
-Corsair 4GB
- XFX ATI Radeon HD 4870 1024MB
- Seagate Barracuda 500GB

was taken up to overclockers by myself and the GFX card was spwated for another 4870 and the memory was changed.

got home and still same problem i then sent the pc back around a month ago and the chagned the GFX card for a GeForce GTS 250 1024MB.

i have been working away so only just got chance to test it again to find its still tearing when any thing is moving fast on the screen .

i have tried a standard vga monitor and still does the same i have been ringing overclockers support for 3 days but cant get through any one got any other idears what could be causeing this .
 
You'll get tearing in any game unless you turn on v-sync. Most games will have the option in game, but if it doesn't, you can force it on via CCC (ATI) or the Nvidia control panel.

BTW, you do realise that the 250 1GB is a downgrade from yout 4870 1GB?
 
its not just in games ... its even watching youtube vids and movies on wmp even with vsync on it still tears.

i think its a 250 .why is it a downgrade .
 
as the above, try turning on v-sync in the graphics options. This should eliminate tearing in games.

Yes a 250 would be a downgrade from a 4870. A 260 would be about the same as a 4870.
 
it might be a 260 ill have a look and another play when get home is there any other settigns i should alter ?
 
not really. You could try running fraps to check that your fps isn't going over 60fps. I have had certain games that seem to ignore the v-sync command. iirc you need Rivatuner to fix that.
 
They don't do a 1024mb 260 (896/1792) so it must be a 250 and yes that is slower than a 4870.

Without v-sync, you graphics card renders and sends out a frame as fast as it can (afterall, thats what you pay the money for) and starts straight away on the next frame. Meanwhile, your monitor is oblivious to all of this and captures 60 even spaced frames a second (presuming your refresh rate is 60) the result of this is that your FPS will be at its highest but you will only ever really see 60 refreshes of this and quite often the monitor will capture a frame right in the middle of your graphics card sending out 2 frame. So if you were running at 90fps the your monitor would roughly capture 1.5 frame every refresh and you would get tearing.

With v-sync on, the graphics card renders a frame and then waits untill your monitor is ready for its next frame and the full image is sent in one go. Only then will the graphics card start on the next frame so you are effectively capping your frame rate at 60 but will get no tearing. The downside of using v-sync is that if you were playing a game that was only running at (worst case) 59fps, you would be almost halving the frame rate at times because it would keep missing the monitors next refresh and so wait for the next frame.

Unless of course you enable triple buffering though that of course introduces other lovelies like input lag and substantially reduced fps. Wonder if the suspension relates to the 3 days comment in the OP? :D

Not compared to normal double buffered v.sync it doesn't. Proper triple buffer with v.synch should be closer to double buffer no v.synch, in terms of fps and input lag, than double buffer + v.synch.

That is where triple buffer can drop frames when needed. There is render ahead, which is not the same as triple buffered and can't drop frames, that introduces things like input lag.

This is one recent article on it that is worth a read.
 
right have been playing with V Sync all weekend
i have had it on
i have had it off
i have had it aplication settings with it on and off

and i still get the horizontal tearing if anything is moving fast on the screen

i have had 2 GFX cards and still have this problem .

am going to ring overclockers up Again tomorow.
 
OP, are you using DVI or VGA? Every recent card I've owned has had tearing when hooked up to a VGA monitor, I don't know whether it was the cards, cable, adapters or monitors but I don't use VGA so it doesn't bother me.

Any chance you could try HDMI or DVI?
 
Sorry im using DVI . on a 23" Samsung monitor .
I have changed the cable
Also i have hooked up a 17" VGA and it still Tears .
 
It doesn't sound like a graphics card problem to me.
It's either V-sync or another component.

Which games are you actually testing it on? Have you tried forcing V-sync on in the NVidia control panel?
 
Hey, i'm having the exact same problem.
Tearing on all video/dvd, even when i move/scroll a window quickly, its even worse on my lcd tv when its connected.
I've tried formatting, updating NVidia drivers.
I've tried forcing V-sync on in the control panel, triple buffering too.
I've tried changing from my 1gb 9800 gt back to my old 512 8600gt.
I've tried new RAM.

No joy at all, any suggestions would be welcomed. I don't play any games, its just a media pc.

BTW its a Intel Core 2 Quad Q8400 2.66GHz @ 3.20GHz / Gigabyte GA-EP45-DS3P Intel P45 Motherboard / 8GB RAM / Gigabyte GV-N98TOC-1GI GeForce 9800GT ATX HDMI Graphics Card / Win XP

Thanks

Tearing ALWAYS happens when you render without vsync on.

Bare in mind that drivers can over ride game settings, make sure your drivers are set to either let the game decide or force vsync on, if neither of these things work then you might have a bad driver install, i'd suggest the usual fix which is to uninstall all video card drives, delete all the install files, use a driver cleaner software to clean out all the hidden files and reg keys, and then do a fresh install of the latest drives.

Do you have windows vista or win 7? If you do and you have tearing on the desktop then something might be wrong with your windows install, they both have vsync forced on the desktop, something like a youtube video shouldn't exhibit tearing under any circumstances, irrelevent of driver configuration. (XP and before the desktop can/does tear)

thanks for the reply but like I said I dont play any games, the problem is mainly with watching video/dvd.
I'm running XP sp3, i've re-formatted already.

its so distracting
