Please check my signature and upload your DxDiag.txt

Make sure your graphic drivers are most up to date. What launcher are you launching the game through. There are two available launchers one from steam and one from UBER. The uber launcher is said to me more stable. Make sure you have all the correct updates to the game. I mean your playing on the right patch. Make sure your direct X 11 version is up to date. Hope this helps.

Works now with other client (without steam ) thy <3

It's doesn't related to other client at all, it's just luck.

Your graphics drivers are extremely outdated:

You need to download and install latest drivers from AMD website:
