Might be worth reapplying that DX9 redist... Possibly a removal, redownload and reinstall of the FC3 module as well. We're also learning that a reboot following these fixes works.

These are things I'd be trying anyway...

I just found out it could be because of inputs folder in saved games folder from the past. This was only one folder I didn't delete. There were some outdated inputs in FC3 AC folders and after deleting them it seems to be OK so far.:)

Well sadly for me nothing fixed the issue. After reinstalling my windows and downgrading my drivers to 331.60 the freezing issue still remains.

Funny thing is I can close it down trough the task manager but I will continue to have freezes every 5 seconds on my desktop ( this is caused by cpu spikes in NT Kernel & System process ) until I restart my computer and considering I've tried the game on 3 drivers now and a fresh win install I can't blame anything else but my gpu. Either that or 1.2.8 is incompatible with 780ti.

How can I downgrade the game to test the previous version?

I also had freeze situations after deleting saved game folder etc. as said above but in one topic http://forums.eagle.ru/showthread.php?t=126698 he disabled full screen and fixed his issues.

I tried it for curiosity and I am able to fly a Su-27s mission an hour if I want without freezes. I think it is worth a try for you too.;)

Denco · July 13, 2014

I'll test it, thx. What is your GPU hornet?

This is what event viewer throws up ( its logged the same time as the freeze happens )

The description for Event ID 14 from source nvlddmkm cannot be found. Either the component that raises this event is not installed on your local computer or the installation is corrupted. You can install or repair the component on the local computer.

If the event originated on another computer, the display information had to be saved with the event.

The following information was included with the event:

\Device\Video7

The same one. I`m still investigating freezes it just hold on.;)

Have U tried to lower the GPU Clock to normal?

Denco · July 16, 2014

Yes I did and its the same. I tried the same with my CPU overclock but the result is always the same.

f-18hornet · July 21, 2014

After some testing I have best experience with this:

http://support.microsoft.com/kb/2665946

I had only once "wanna be freeze" after 10-20 minutes of flying but application did freeze just for 5 seconds or so and then I could go back to the game with no application crash. After that I had at least eight flights without any issues.

Time at pictures is real time of game play and no time warp was used. It is not perfect but better than nothing. I hope this could help to you too.

Try downgrading your drivers back to 314.22

That fixed the freezing I and other Nvidia user were getting with 1.2.8.

I rma'd the card since I suspect its faulty. Will let you know what happens once I get a new one.

PE_Tigar · August 4, 2014

I've upgraded to that same GPU (I think even the same card) and have the exact same thing happening. I've turned off hyperthreading in BIOS and the frequency of freezes decreased, but they're still there.

rajdary · August 5, 2014

Im also geetting freezes with my Asus 780ti, only in DCS not in any other game, i start and after about 5 seconds the game freezes and i have to reset my comp. There is no way to play. i get a blue screen with something about mindump and some dmp references.

Im stuck

Can't find the post, but another user of the 780ti had the same issue. He ended it with an increase to his fan speed as heat turned out to be his issue.

Give it a go. or u are not getting overheating problems?

thanks, but how do i increase my fan speed?

f-18hornet · August 5, 2014

Use MSI Afterburner to manually increase RPM. It seems to solve that VRAM overaheating problem.

rajdary · August 5, 2014

Ok, problem solved, before going for the gpu fan speed i tried erasing DCS folder in saved games and that has worked for me.

Thanks to all for the help

PE_Tigar · August 6, 2014

I've installed a manufacturer's utility for my graphics card (Gigabyte something something) and set the fan RPM to manual (it lets you set up step increases for fan speed based on GPU temperature). I've played for about an hour yesterday and no problems so far. I did notice that the fan was really sluggish on auto in idle - maybe the problem is in GPU switching fan speeds back and forth based on 2D-3D transitions (that happen quite a lot in DCS - launcher, 3D part of the sim, than launcher back again, than F10 map view, etc...), and than it just misses the switch to higher RPM at some point...

Can you pleas post a screenshot of your RPM settings? I'm still struggling with lowest stable RPM.

Denco · August 6, 2014

I see that there are other 780ti users who are experiencing the same issue.

I find it strange that increasing the fan speed fixed the freezing for some of you. Using Afterburner to check my temperatures and it never went above 70. Considering DCS is a simulator it makes sense since all of the sim are more cpu dependent.

Anyway I'm still waiting for my card to arrive back from RMA.

I've upgraded to that same GPU (I think even the same card) and have the exact same thing happening. I've turned off hyperthreading in BIOS and the frequency of freezes decreased, but they're still there.

Have you tried other games. Try Metro LL or Rome 2. I've experienced a lot of driver crashing in those games. Also try 3DMark 11. See the threads bellow for more answers.

You are free to chip in on both of the forums for a discussion and your experiences with the gpu.

Just a question is there anyone with this issue with Evga GTX 780 Ti OC?

Sabre-TLA · August 7, 2014

Check out this thread. GPU overheating seems to be a common cause for crashes.

tango4 · September 23, 2014

Hi everyone,

If anyone is still monitoring this topic (especially Denco), I also have this issue.

I have a Gigabyte GTX780Ti as you and have those freeze. After a random amount of time, I go from 60fps to either 20 fps (with grapics card core freq locked at around350MHz) or, more frequently, to 1 or 2 fps.

I have to completely reboot my system to regain control, as I also have one or two fps in windows.

This has been driving me nuts for months, so if anyone has a solution or explanation, I would be really grateful !

I have placed a support ticket with DCS, but for the moment, no solution.

Please note that my graphics card does not seem to be overheating, and that I don't have crashes with FSX, P3D or Xplane10.

I already tried reverting my cpu to factory clocks, but it did not help either.

Best regards everyone.

Charles

I see you turned down the CPU overclock, did U do the same for the GPU? That has worked for some users of the Ti cards in other threads.

tango4 · September 23, 2014

Hi Atalia, and thanks for you answer.

Actually, I did downclock the GPU, but I did not do it in a very thorough way, and now that you talk about it, I only turned down core clock, and not memory clock.

So it might be worth a try.

I have a Gigabyte GTX780Ti factory overclocked.

Do you think I should downclock it to a factory Gtx780Ti non OC, or even lower to a regular GTX780 ?

And is MSI Afterburner ok for it or is is there a better tool that you would recommend ?

Anyway, thanks for having taken the time to answer me.

Charles
