I had the same problem today.
m_VertexBuffer->Lock(m_nNextVertexData, Size, &pData, VertexLockFlags) failed
at Src\D3D9DrawPrimitiveUPWrapper.cpp:293
with error D3DERR_DEVICELOST
....and it's very annoying and it happens time by time.
Please find a solution to fix this issue because this makes the game completely unplayable.
Thank you for letting me know guys.
Maybe I found a temporary solution. If your game crashes/freezes just press CTRL+ALT+DEL then go back to your game. It will unfreeze your game - at least it worked for me several time so I could go back and proceed with my mission...
Hey folks,
I am running the game with RTX 2060 GPU and it seems I have the same issues. I can't play longer than 20-30 minutes because the game just crashes every time...
Did anyone find the solution? Will they release the new engine in short time?
