Some users have experienced issues with the update. Win7 users appear to have the most problems. Update 2.006c Dear Pilots, A day of hard work and buying videocards in stores brought some results. First off, we managed to reproduce the 'rainbow particles' problem and find out its cause. It turns out that newer Radeon cards or its drivers have problems handling indirect addressing in shader code, while older Radeon cards and all GeForce ones don't have such problem. We used a different, a bit slower addressing method and the problem should be gone now. The 'ghost stripe in the hangar on the left' issue remains and also seems to be isolated to a wider range of Radeon cards. This isn't a game breaking bug so we decided to slow down a bit and find out its cause after the holidays. Second, we haven't succeeded in buying a working GeForce 780 (the used one we hastily bought turned out to be broken) but we contacted several owners of such cards who 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, sometimes with the same card models (NVidia 780)and a similar advice is given on their forums as we do: Variant A: Try to lower the maximum GPU clock of your card by 100-150 MHz. Variant B: 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: So, this update fixes the following: 1. 'Rainbow colored particles' issue fixed on some Radeon models; 2. AI now handles more than one take-off and landing in a mission correctly (previously it could perform taxiing in a wrong way).

The 780 issue 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: PS 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.

a bit of hope for win 7 users
My GTX 680 card seems to handle things very good, I haven't had time for long flights but I see no other problems than Win 7 related ones, witch I fixed. - 216th_LuseKofte
