Way to stop 5970 using 2D clocks in 3D games?

I've noticed an odd kind of screen tearing in games, where only the top half tears away from the bottom, I have vsync enabled/forced and it only appears to happen when the game isn't taxing the gpus.

Looking in MSI Afterburner I can see that the card is constantly clocking up and down during these areas, as soon as you get to some action where the gpus are doing some work everything is as smooth as you could want and clocks are locked in 3D mode.

I've tried disabling Crossfire, overclocking, setting a new 2D profile in Afterburner, updating/downgrading drivers but I'm having no luck, Supreme Commander 2 and Fallout : New Vegas are being especially affected by this.

Any ideas?

Cheers.
 
Something that I think might be related, a 3D graphics program I use is acting sluggish and I noticed that when signing into windows (7) the screen fade effect is really juddery.

Do these cards have 2D clockspeed issue?
 
I noticed this lately with my 5870, I was playing Borderlands in window mode, so I'm not sure if it was related to that, but my 5870 was staying at 400Mhz core, so I upped it with MSI afterburner and the performance went up to what it should be like.
 
Power state is the route of all problems.
Happens all the time, but many ppl dont notice it. 3dmark2001 is a classic example when powerplay starts messing around with the game.
Happened to me in SLI with nvidia / crossfire.
The only way to really eradicate it is to reprogram the power state.
 
Wouldn't upping the idle clocks sort it out? Or would that make what I seem to think is a not too hot running card into a toasty one? :)
 
Can't you edit them like I did mine by using notepad? I know some drivers restrict flexibility, but I found 10.4's and 10.11's give me the lower idle clocks that I want.

I just tried creating a profile and editing the values, it accepts 3D clockspeed changes but the 2D clocks are apparently brickwalled at 400 no matter the "Want_0" values.
 
i hate powerplay.....with every driver release on the 5970 ive been hoping for a fix or option to turn it of but nothing......there our cards ati let us turn of this **** if we want!
 
Maybe the only option would be to change the values in the bios. Keep the 157mhz idle clocks but substitute the 400mhz ones with the full power clocks and voltages? Correct me if I'm wrong tho, also have you tried the afterburner option of forcing 3d voltages permanently?
 
i've got exactly the same issue, tried the 10.10e drivers, didn't help. tried fiddling with afterburner/statistics server which hasn't helped either.

i thought it was just doing it when a game was launched after a previous go on a game, leading me to have to log off, log back on (only solution i've found without restarting), but it did it mid-game on l4d2 earlier :mad:
