Hi Juanlo,
I'm still having issues with this new driver in the form of "horizontal tearing". It happens in game when you quickly move the point of view and occurs so far in bf3 and also borderlands 2. I've tried your "game time" fix (50 to 65 fps limits), v sync and lower graphic setting. None of them seem to have any effect. Something also I've noted, the graphical problems are more blocks rather than on a horizontal line. This problem has only been since the last driver install. I'll try to nut it out from this end but any ideas for your end would be greatly appreciated. System = i7 960, 3x7970, 875w + 450w psu's, win 7 64 pro, 12gb ram. Gpu's stock volts and clock, CPU 4 ghz on water. I sort out my signature soon so I'll list everything. Keep up the excellent work!!!!!!!

It's great to have you here Juanlo!

In Battlefield 3 I also noticed a little bit of horizontal tearing, even after limiting framerate, but for me it's the same visual tearing that I get in any game with vsync disabled and I can play perfectly with it (this weekend I have played over 8 hours of BF3 and it has been a wonderful experience). I don't know, maybe I just haven't paid attention to the problem you are describing and I just concentrated on playing. But I will take a closer look as soon as I can.

Anyway, if anyone else could share their thoughts about this problem, it would be very helpful.

To correct it try limiting the fps to your frequency of your monitor then adjust up or down +/- 1 fps at a time to see if it corrects it.

Here are a few commands you can play with to get your setup running smoother.

Use the tilde key next to 1 on keyboard in game.

Gametime.maxvariablefps 60 - (Limits fps change to what you want)
RenderDevice.ForceRenderAheadLiimit 1 - (Sets how many frames to pre-render)
RenderDevice.TrippleBufferingEnable 0 - (Enables triple buffering if set to 1)
Render.drawfps 1 - (On screen display shows fps)
Render.perfoverlayenable 1 - (Enables the performance overlay)
Render.perfoverlayvisible 1 - (Shows the performance overlay)

The performance overlay is helpful for adjusting your renderahead limit. Rendering to many frames taxes the cpu pretty hard and you should be able to see it on the overlay. I found that with 3 7970's and my cpu renderahead limit of 1 gives me the smoothest game play. Mess around with the setttings until you find a combination that works for you. Also limiting the fps + or - a frame or 2 near your refresh rate can move the tearing so it is not visible sometimes.

Here is a few quick video clips I recorded of my son playing. As you can see the tearing has been eliminated for the most part unless I just can't notice it. Sorry for the poo quality recorded with my Iphone.

Also each game is a little different, some take a little more time to get setup correct. But yeah, vsynch is sometimes a nightmare to get working smoothly in games. I will post my settings when I get home from work.

I did some testing in game:

With Vsynch enabled and trifinity enabled the graphics were jerky but synched. Disabled trifire and run one card and vsynch worked fine.

I messed with some of the setting I posted above and was able to get the game smooth with trifinity and vsynch enabled but mouse lag was terrible. If you look at the performance overlay with crossfire,eyefinity and vsynch enabled you can see the graph going crazy. You disable vsynch and it smooths out.

Settings I am using are renderahead 1, no vsynch, rest of the settings ultra, using in game 2xMSAA. I get no noticeable tearing with vsynch off. What Monitors are you using BTW?

Thanks all for the advice, we're getting somewhere. Have been able to get 90% smoothness from setting the refresh rate to 50 fps (monitors are benq bl2201 with a refresh rate of 60hz). I might drop it to 48hz to stop interference from the lights in the room, other than that a great result. Also my gpu's are running a bit cooler, 65c max. I'll be doing the change to win 8 soon, so I know I'll be back here soon with more questions. Thanks again everybody.
