We have issue that many of our users are reporting that the game is forcing Dx9 on launch.
We told them to try using -force-d3d11 command but it still launches with Dx9.
Also some of our office computers have same issue, even if they have exact the same hardware configuration as other PC’s on the office (gtx 960 and 750ti).
It happens both on the editor and build, and it started to be an issue after we have moved from 5.4.2p4 into 5.4.3p4 version. Same issue happens on 5.5.
We have tried creating a new empty project and launching it on PC’s which have the issue with our game and it gives same result. Even having GTX 960 onboard forcing usage of Dx9.
The only common thing we thing found was all raports we had about that were using Windows 7. But still, the PC I am using at home is also W7 with GTX960 and it works fine.
I have the same issue - workstation, windows 7, x64, gtx 470 - latest drivers etc.
the error code of the editor console log is also 0x80070057
dx9 and OpenGL 4.5 works fine
One of the proposed solutions for the error 080070057 is related to the decimal symbol - i am not on my workstation, but it is w7 in english and with german date/time/notation. Will try to change it once i am back, but already asking here if you people have similar setups with differing symbol settings?
I would say its more like a workaround since we cannot force all of our users to download this. Also it won’t fix users using other system than W7 - as it also happens on W10.
