Gaming Laptop configuration optimisation

[euramer]

Hello, I really enjoy the game, but I have two types of problem and I tought that I had a good enough configuration with a recent 6 processors i7, 16 Gb of Ram, 512 Gb ssd, Nvidia 2060 and a 4 K screen.
My first problem is a game (Vulkan ?) freeze which usualy happen after 30 mn to 120 mn of game: I haven't found a solution except a reboot of the computer.
The second problem is just ennoying, but doesn't crash the game: The screen goes black for a few (2-3) seconds and comes back. It must be linked to the Video card Nvidia 2060 which is driving a 4K Screen at full resolution.
Can you help me? Should I modify/check some parameters?

5 jours plus tard, je n'ai malheureusement pas eu de réponse à mes deux questions: Est-ce qu'il existe toujours un support technique pour ce jeux?

It seems a driver or a hardware problem. Did you update all? (with motherboard).
If you have new generation gig, maybe you'll have to wait for some official driver fix.

ErissN6, thank you for your suggestion, I have the latest update on my video driver, I have also tried to reduce the quality of the images, but not the 4 k resolution of the external screen.
