Asking folks to watch a video probably won't get you the help you desire. I suggest you post the specifics of your issue here and let the members view the video, if needed, afterward.

Just a recommendation to get more help.

Good luck!

I'm sorry. it's hard for me to type much because I recently broke my collarbone and it was much easier to make a video.

I already cleaned out my drivers too.

It looks fine to me, Fermi cards early on had a Lot of rendering bugs due to drivers and Kepler is no different. A clean install might help but doubt it will change anything and even if you returned for a different sample chances are you might have the same problem but never know there could be differences between samples. Beyond that you can live with it unlike having a physical injury.

Will do. I forgot to add that I already RMA'd the card and it is still unable to OC. That's why I think the card itself is fine. I think it has to do with the Mobo or faulty PSU.

Turning HT off made no difference. Also, the 2700k is at stock clocks.

Brand new comp, haven't gotten around to OC'ing it yet.
The temps are in the 30's mostly.

Good temps, what is the reading on the 12v rail during average and full load?

I'm sorry I don't know what the 12v rail is. Noob here!

I watched the video in 1080P. I don't think anything is wrong with the card or your system. I think you are being overly sensitive and expecting absolute perfection. I really had to look hard for the issues you pointed out and then even after seeing them they didn't bother me one bit and seemed like normal minor glitches in the games or drivers. I have seen similar things like this on every video card and console I have owned.

I don't expect a new card will fix these issues and would like to see a video of the same footage rendered on the new card. I would love for you to follow up on if the card you get back after the RMA did fix these things. I am now wondering if I should look for these things in the future.

Good luck and please keep us posted.

OK, thanks for your feedback, but I am still wondering why I can't OC it past 30 on both offsets...

Not sure why you are having overclocking issues but I think I may have some insight.

Have you thoroughly read a detailed overclocking guide yet for the 680? My understanding is that overclocking is very different on these cards due to the fact that they will dynamically and aggressively auto overclock. I believe you have to change the constraints on the TDP and possibly add voltage too, if you want to push the card. In other words, the conventional methods of overclocking a video card no longer apply to the 680. See if you can find a good guide or a youtube video to help.

Texture flickering is normal and to be honest even my GTX 680 SLI are not the best overclockers. I know now that I should have gone with the 7970's, but no real regrets since the GTX 680 sip power. Hopefully driver update in the future will solve these problems. Try using Afterburner to OC!

OK, I think I'm actually OK with the OC. My core clock was near 1250. That's good right?

Now I just need to figure out why my Ambient Occlusion is messed up.

Why? The only thing I would like to accomplish now is to fix my messed up ambient occlusion.

yes. My AO is set to High Quality and FXAA is enabled. Every game I play has all these weird flickering shadows that usually occur if another object is in front of it. Like in Battlefield 3, when my gun goes in front of a shadow, the shadow disappears around it. This gets annoying when you are moving and there are flickering shadows everywhere...

Well 30mhz is pretty sad indeed but I believe that it is software capping the clocks. I am beginning to believe that the gtx680 and 670 are pretty close to their hard limit on the reference models power wise even though the gpu could possible handle a lot higher clocks. Like the high end amd cards and high end kepler I wouldn't be surprised that a modded card could hit 1.3-1.5ghz on water with an evga untouchables or a zombie card providing extra power.

I have seen one complaint of one gtx680 shorting out when the owner had overclocked the core by 100mhz while playing bf3. It was a reference model and one of the power vrm phases had shorted (mosfet). It lasted for about an hour then blue smoked.

I've seen that before on my gtx460, the memory doesn't like heat all that much. Manually set the fan speed like 60 or 80% and keep it fixed while gaming. It will keep the temps down and especially the spikes.

My fans are at 85% (highest) and i still get the weird shadow flickering. I may do a clean install of Win7

I think that you should just sit and wait for a new driver release to come out. I had to wait two months once due to a bug that caused fallout 3 to crash back in 2009 but every other game worked.

I already have the 304.79 beta driver. No difference. Nobody else has the same issue as I do???

I'll make my issue clearer - Ambient occlusion is causing crazy flickering shadows all over the place - lines, flashing, disappearing shadows - you name it. It seems that when an object goes in front of a shadow, the shadows disappear around the object, creating a flicker effect. It is SOOO ANNOYING.

And this is in EVERY GAME I HAVE - Crysis 2, BF3, CS:S, Skyrim, Fallout 3, etc.

I am still having what I expect to be the same issue you have. (Video is no longer available).
Smoke is flickering, and when I'm playing games like Battlefield 4 nowadays, it's really annoying. Especially on the boat levels. (lot of smoke)
Has someone found a fix already?

If it's usefull these are my specs:
i7 3770K @ 4,2 Ghz
Asus Sabertooth Z77
Corsair H100i
2 x GTX 680 4GB (Palit Jetstreams) in SLI
Corsair Force 3 SSD (240GB) where the games run from
Asus Xonar D2X soundcard
XFX 1050W Black Edition

Running on Windows 8.1 up-to-date version.
Drivers: 331.65
