Possible to force DX11 after March 2025 update?

[flooo]

FPS dropped for me significantly after the March update.

I just started playing this game for the first time the weekend before the update dropped. Performance was great with 4K and High-Ultra settings with my W6800X. 2 days later, after the update, suddenly there are massive lags and fps are much lower.

Before the update there was a pop up during game launch asking me to pick between DirectX 11 or 12 – I chose 11. (somewhere it said DX12 supports Raytracing but for most users DX11 is recommended)

Release notes of the March update say: "Improved graphics adapter detection at startup, with automatic selection between DX11 and DX12"

Could it be, after the update the game always uses DX12 now? Any way to force DX11 / check what the game actually uses?

I tried but not sure it works. Do you know of any way to confirm if the game really uses DX11 or DX12?

Hover your mouse over some video settings in the menu - when you run dx11 some of them will state, that you need dx12 to be able to run them. When you run dx12, you won`t see such notes.

Thank you, this indeed was very helpful. I can confirm with the -dx11 start option the game successfully started with DirectX 11 - game options like HDR were disabled and showed the warning about it being only available if I switch to DX12.

I believe performance is better this way, although I cannot directly compared it.
