Hey all,

This is the rig I'm working with:
I7-3930k
Gigabyte g1 Assassin2
2x Gigabyte GTX 770 GDDR5-4GB WINDFORCE 3X Graphics Cards GV-N770OC-4GD
G.SKILL Ripjaws Z Series 16GB (4 x 4GB) 240-Pin DDR3 SDRAM DDR3 2133 (PC3 17000)
Samsung 840 EVO-series 250g SSD
Cooler Master Silent Pro Gold - 1200W

Display: Samsung UN60D7000 TV (240hz refresh)(set to auto motion plus: Clear setting)

About 2 weeks ago I got my second of the windforce cards in and bridged them together. After getting everything connected I decided to fire up Metro: Last Light to see how it looked. The texture detail and fps were great, but I noticed lots of tearing and stuttering in the intro when the camera would speed up, and when I looked around quickly, but it never slowed down, just stuttered/tore. I've tried a bunch of different "manage 3d settings" in the Nvidia Control Panel, but the in-depth settings within that menu definitely go over my head a bit. It seems as if Adaptive Vsync with triple buffering helped the most so far, but even with that tears will catch, and I've tried different in-card vsync and in game vsync combos and nothing totally fixes it. I also tried another game (FarCry 3) and once again it looked great but tore when the screen moved quickly. I looked into the 240hz refresh of my TV display and heard things about it being an internal only 240hz refresh rate and that the 240 label is actually a misnomer. I tried looking into overclocking the display rate past 60hz on my nvidia control panel custom resolution, but my display wouldn't accept anything much over 64hz because the TV doesn't find a video source for about 15 seconds then it reverts the settings.

so far I've tried:
-disabling SLI (tearing remained/was worse)
-adjusting various Nvidia settings/game settings
-disconnecting second monitor
-going through and ripping out all files and registries associated with Nvidia and re-installing drivers.
-One of the 4 different 8 pin power connectors needed for the 2 cards is off a 2 4pin Molex connector, but I figured anything causing power issues/SLI bridge issues would do more than tearing.
-my HDMI cable was a fairly high-end gold tipped one from 2011 so I'm assuming it's 1.4

Am I wrong in thinking that my current rig is more than powerful enough to run both of these games at absolute ultra graphics with flawless execution? Am I barking up the wrong tree looking into my display/Nvidia output refresh rates? I've considered trying re-removing all the drivers with driver sweeper, but don't have high hopes.

This forum community always rocks, so thanks in advance for any help.

Screen tearing is from the mismatch of refresh frequencies. So this doesn't necessarily mean that your graphics set up is underpowered, but could be that the display, in your case a tv, isn't able to keep up with the frames rate that is being rendered. Stuttering is just something that comes with the use of multiple cards in SLI from what I understand. The 240hz misnomer is what I'm going to assume Samsung's clear motion rate which generates artificial frames to help smooth out motion blur.

With all this said I'm going to point fingers at your display for the most part. Perhaps the latency isn't that of a typical pc monitor and that is causing issues at higher framerates due to the mismatch in refresh rates and frames per second rendering. SLI has its issues and micro stutter is the main one or at least the one I hear and read about the most.

This is basically how I understand it. Hopefully someone can elaborate on what I said or correct me if I'm wrong.

Not a problem with your rig. This is due to the "artificial" refresh rate used on many televisions these days. As previously said, a lot of these companies use various forms of programming that provide filling and/or filtering of frames that makes the overall video more seamless to the human eye, *like* a much higher frame rate but NOT actually a higher frame rate.

*sigh* that's what I was afraid of! =/

It sounds silly, but if I turn OFF the clear motion plus sensor and keep it at a true 60hz, which is what the GPU control panel says it's pushing, would that help at all/ or dropping the GPU hz output to 59 to keep below the 60hz of the display? I have always loved being able to play epic games on a 60 inch TV with surround sound, etc, in my livingroom, so this is quite the bummer for me. If I had a monitor with a true 120hz refresh, and I went to the Nvidia settings panel, would increasing past 60hz be a possible option? or is 60hz output from the cards as good as it gets?

As always, thanks for all the help everyone, it's nice to have help deciding which route to go!

I have a samsung tv that offers the same clear motion technology and I've had no issues playing games on it. What I would do is download a program such as EVGA Precision that allows you to tweak the gpu settings. I do believe that gigabyte has their own sort of program, but I think they're all relatively the same for the most part. This program would allow you set max frames per second. I would play around with that setting until you can find something your tv can display without issue.

Ok sounds good, I'll check out Gigabyte's site for something similar and let y'all know how it works. Thanks for the help!

So I downloaded the Gigabyte OC Guru II, and it has options for GPU clock, Memory clock, and voltage adjustments, as well as Temp and Fan adjustments. As for the Resolution adjustments though, it has nothing that the Nvidia Control Panel doesn't already have (pixels, color-depth, and hz refresh rate), and can't find anywhere to adjust max frames per second. Are there any 3rd party programs that might do this? I've double and triple checked that absolutely everything has the most up to date drivers, etc, and it's all good. I've been trying to figure this out for weeks now and was hoping to have it solved by launch of Titanfall/ESO, but I'm starting to lose hope, and honestly becoming very very frustrated. I would consider my rig fairly decently high-end, and my TV (while not 4k ultra) pretty nice as well, but am having to play games with horizontal rips anytime the action heats up. I'm about to try contacting Gigabyte but that likely won't resolve anything. If anyone has any other suggestions, I'm willing to try almost anything at this point =/

I hate to go back to it, but if I had a 144hz monitor as opposed to the 60inch Samsung TV, would this no longer be an issue at all?

Thanks,

Yeah, I have a 144hz monitor. Once I put my build together I noticed tearing unless enabling vsync on my computer with normal 60hz monitors, which would be a waste of the power of my rig. Once I got the new monitor, vsync off, no problems at all.

I do believe that most TVs have a slower response time than a better computer display. This could be the biggest problem with screen tearing. That and adding the already not perfect SLI. When you disable SLI and use one card, are you keeping the settings the same as when using SLI? If so, one card definitely can't handle the work of 2 therefore inconsistent frame rates that do not match with the TV or display you are using.

I would find a decent monitor to use instead of a tv.

Also, try EVGA Precision. I know it has FPS lock and is visible at start up at the bottom of the window.

Got EVGA Precision (which was way better/more versatile than the OC Guru II so thanks) but locking my FPS at 60 just lowered the quality of the image while retaining the tearing. Currently looking for a buddy with a higher end refresh rate monitor. If that fixes the issue, then the answer is in site... just not the ideal answer I wanted lol. Thanks as always fellas!

I read something simillar on another forum their solution was to ensure the samsung tv was in PC mode. It might be worth a shot, if you've not already done that.
