Question / Help Distortion and Discoloration - Dirt 3

[duzy_wonsz]

I've recently reinstalled my Windows 10 install because I couldn't get that game (Dirt 3) running.
Now as the game starts fine I've setup OBS Studio, Installed all Graphics Drivers and a K-Lite Codec Pack.

Unfortunately using Game Capture in OBS Studio shows me this in preview window (and records this way aswell):

Any ideas how it can be fixed?

Switch the renderer to Direct3D 11 instead of OpenGL.

THANK YOU :)
I thought that D3D 11 was default, but I must have changed it on previous installation and moved it with config.

Thanks once again :)
