"....encountered the driver crash problem after several minutes of playing and found a possible workaround. It looks like this is a videocard problem, most likely caused by videocard power subsystem (not neccessary PC power supply unit itself) of 780 series card not being stable enough for GPU frequency when close to the limit, resulting in some instructions being processed incorrectly. This issue appeared as a direct result of DirectX 11 implementation and optimizations - your graphics card is working with much more efficiency (it is not about GPU load and temperature). There is no apparent solution on the game side short of removing the optimizations and returning to 2.005 version performance since the problem is caused by incorrect work of a certain graphics card model.
You may say that the card works fine in other games, but this is not really relevant since most modern games don't use such vary renderers capable of drawing giant landscapes or use popular licensed engines which have optimizations in graphics drivers and hardware made specially for them. Sims similar to ours have similar problems...."
Therefore, please,.. take into consideration that the only way to contiue flying il-2 BOS for the time being is reverting grafics drivers to an old version:
"At last we have found a working second hand NVidia 780 Ti device and figured out what to do if problem of "Constant crash after 1-3 minutes of flight" is presented.
First of all, we have reproduced this problem on most recent drivers 376.33. Indeed, problem appearing constantly. It can be removed only by reducing all Graphics options to minimal settings, and even this may be not the solution in case if resolution is more than fullHD.
Also, investigation with using of debug version shows that hardware driver stop working randomly during standard procedure of dynamic loading of graphic data, which works OK for all others video cards.
As we have supposed before - it is NVidia problem and it is depends on driver version. So we have tried this solution and it works good - on our 780 game become to work stable for hours.
Uninstall completely all NVidia software and drivers (using Control Panel, Programs and Features), install NVidia driver version 368.81:
Windows 10 64-bit:
Windows 7 64-bit, Windows 8.1 64-bit, Windows 8 64-bit:
We have wrote a e-mail to NVidia support regarding this recent drivers problem, but they're on the holidays and will respond in January in best case.
If you will do the same and will write your own claim to NVidia with all these details - this may help to force them to solve the issue in actual drivers"
You should start a thread titled " Calling All 780 Owners" or something along them lines and promote your problem there!!!!!!!!
So it seems 780's are left hunging around,... it seems to be nobody's problem... 1C says it's NVIDIA faulty drivers implementation.... NVIDIA labs (http://surveys.nvidi...8f07694a40f8ac6) needs info to be provided by 1C & 780's owners...
...reverting the drivers version, it's not the way to proceed, new versions appear to optimize new games, and fix existing issues, and il-2 users want to also get benefited from them. Moreover, i'm not only flying il-2 but also other flightsims and games. It's not a matter of going back and forth with drivers versions depending on the game to be launched.
It seems 780's owners who are suffering this issue are being told that We're the only ones impacted... so it our problem....
This is what i was answered with at NVIDIA's forum:
If you want it to work for now, your only option is to revert — no way around it. It is the coordinated effort between the two involved entities that forces you to one path or the other in the meantime.
But this is a User-to-User Forum and not necessarily the quickest or surest method of contact. You need to direct everyone to the NVIDIA Display Driver Feedback Form (http://surveys.nvidi...8f07694a40f8ac6) with as much of the tech info as possible. It's a "direct line" to the labs...
Unless i'm wrong (And I hope I am), 1C developers have stated that this is an NVIDIA faulty drivers implementation and THE SOLUTION is to revert to an old driver version and stay with it, for all of us with a NVIDIA 780 card... Therefore i am led to believe that they are not going to be worrying about us any more.... So please, all of you (780's owners) are kindly requested to fulfill that form (http://surveys.nvidi...8f07694a40f8ac6) if we want NVIDIA to find a solution...
Looking forward to seeing this issue will be solved...somehow..someday..,
