SLI issues with fullscreen games (780M sli, clevo P370SM3)

Okay, hi everyone. Just got my new machine in my sig from Mythlogic on Monday, and I'm seeing some issues with a lot of fullscreen games when SLI is enabled. I originally thought it was the new 331.40 drivers, but I removed them and installed the 327.23 version and still I have issues with some fullscreen games. Not all mind you; games such as Trine 2 and Sleeping Dogs got a whole lot better with the new drivers, but games like BF4 beta and Black Ops 1 and Shattered horizon get a lot of flickering and red/blue/yellow lines across the screen and eventually they crash my video card driver. I initially thought it was my second monitor causing issues, but it does the same thing with that removed.

Now if I run my games in windowed mode, I get very similar performance and no flickering/artifacts/etc, but not every game has/likes windowed mode. If this is just an example of a couple of games where I have to force them to only use one video card, I can understand that to a point, but sometimes it isn't possible and frankly, it should just work >_<. Is there anything I could do to help this? Some windows settings, or do I need to re-seat my SLI bridge or somesuch? (assuming I even have an SLI bridge in this machine; and that it isn't a motherboard-only thing. I'm new to SLI, forgive me friends).

Or could it be that 314.22 drivers are simply the best for SLI-ing and 327.23 and 331.40 are both pretty bad at it and I just need to downgrade a little further? I would mind that a lot less; as I expect a better new driver will come out soon that would fix the issue that the last two I called would have (assuming it is the drivers).

 

Run the games in fullscreen borderless window.

 

I kind of said not every game likes window mode or has a window mode.

 

I've never seen a game that was less stable in windowed mode than in fullscreen, plus windowed makes task switching much easier and less crash-prone. It's usually the fullscreen games that have issues. Most games have a built-in method of enabling borderless windowed mode, either through in-game settings, config files, or console commands. I also use this small external program for games without the built-in method.

 

Well thanks for the tool. I went and flash my vbios to see if it'd help and apparently that fixed even BF4. So I guess the stock vbios is really terribru

Thanks anyway octiceps ^_^
