Close witcher3.exe process from task menager or restart ur o/s. If that doesn't help then:
Change in gog settings to lunch other dx11 mode or dx12.
If still you have problems then:
Cause of the crash issue in DX11/DX12 may be:
- Sometimes are wrong user.settings files in <ur documents>/the Witcher 3 folder(u have to delete all user.settings files) or no system privilege to run game exe or to save game settings files in dokuments folder (runnig game exe as admin may help with that) .
- Wrong or old graphic drivers or non
https://www.microsoft.com/en-us/download/details.aspx?id=35] directX update[/URL] or non
https://www.techpowerup.com/download/visual-c-redistributable-runtime-package-all-in-one/] visual c++ redistrib update[/URL].
- Many problems also causing mods or changes that they made in some game files, that steam/gog verify/repair option cannot recognize, even saves can be broken because of some mods that was used at progress in this save(you have to run older save or new game). Even uninstalling game do not remove mods from game files, you have to manually delete whole game instalation folder to be sure that no mods left there anymore.
- For others only using DVXK dlls can help running DX11:
if ur GPU supports Vulkan technology, then download DXVK dll:
~ download newest "dxvk-...tar.gz" from:
https://github.com/doitsujin/dxvk/releases ~ unpack this file and from "x64" folder copy: "d3d11.dll" and "dxgi.dll" in to the same location where is the game .exe (This will force the game to use vulkan instead of the DX11)
