If you are having problems loading VEGA Conflict in Steam while on Windows 10, or if your GPU usage gets incredibly high when the game is inactive, you may be experiencing a known Unity issue.
By default, Unity player will try to use DirectX11/12 to render graphics. However, Unity is currently experiencing an issue that has trouble with DirectX11/12. We recommend forcing Steam to use DirectX9 instead, as it doesn't have this issue. Follow these steps:
1. In steam right click on the game -> Properties -> General -> Set Launch Options
2. In the popup that appears, type the following: -force-d3d9
Don't remove the dashes, type it exactly as displayed above.
This issue is not likely to resolve soon. While Unity has a fix for this issue in its later versions, we are holding off on updating (as doing so will remove Webplayer Support).
