Blackbird Sims / Milviz Forum Archive

First of all, I want to thank the help you have given me in this forum, with which I have been able to solve some problems that I have had. My most sincere appreciation.

I had to change my computer to a more up-to-date and powerful one than the previous one.

When I go to start the plane I get an error message which does not allow me to continue. I have done the following tests:
* Drivers in their initial version and updated.
* With and without shaders.
* With and without True glass.
* High and low definition graphics in the aircraft installation.

How can I solve it?

Simulator version: PREPAR3D v5.1
Airplane version: MV_KA350i_v1.2.0_20201109.exe

Computer descripction
Procesador: AMD Ryzen 5 2400G
RAM: 16 GB
Windows: 10 64 bits
Video card: NVIDIA GeForce GTX 1050 Ti

Unfortunately a 4gb card isn't going to be enough vram to run this in V5. On my system it is at 5.3gb with no addons.

Sorry I don't have a better answer.

I get the same thing with a 2070 8gb. I get the error everytime rendering it unusable.

I've just upgraded to a 3090 and I'm getting the same thing. I managed to make one full flight after disabling true glass but now the problem is back. Very frustrating.

These types of crashes are very hard to nail down and can be caused by any number of things, especially if you removed TG/RL and still have it.

90% of them I have seen are related to DirectX12 and not limited to P3D only, one need simply do a check on YouTube/Nvidia Support or any gaming sites to see it is a fairly common issue.

DX11 on P3DV4 and DX12 on P3DV5 are very different animals so you can't really compare what works between versions...

In a nutshell:

"In order to prevent any rendering or GPU computation from locking the system, the Windows Operating System kills the GPU driver whenever a rendering takes more than a few seconds. When the driver is killed, the application using it crashes automatically. Since we can't possibly know how long a rendering or computation will take (it depends on the GPU, the drivers, the OS, the mesh size, the texture size, etc.), we cannot put a limit on how much the computer can process and avoid the crash."

list of possible culprits:
1) Could be a bug in the P3D rendering engine or our implementation of TG/RL in DX12(but unlikely if you disabled it)
2) Not enough memory on your GPU (In my experience 8GB is the barest minimum for V5)
3) Outdated/Bad video driver install/Driver bug
4) Overclocked GPU - even factory overclocked models (Try downclocking to stock clocks)
5) Too high of settings in P3D (overloaded GPU didn't respond within TDR limit) Unlimited FPS etc.
6) Failing hardware

You can increase the TDR values so that Windows will not throw a crash so fast but if there is a Out of GPU memory(OOM)/driver/software bug this will not fix it.

Here is a short guide on how to do it. There are also many video on Youtube. Also note you may have to redo these edits anytime you get a windows update or upgrade video drivers etc.

FYI a newer version of Trueglass is in beta right now that may help some people (obviously it can't fix low GPU memory or hardware faults). Keep an eye on this forum or if you are really interested you can join the TFDI discord server and get in their tester area/program if you have their 717.
