Witcher3 and ray tracing on Arc770

[Roflosaur]

When ray tracing is on, lighting glitches (video in attach). Also there is some vertical seams on screen center when the camera gives a close-up of faces, but I couldn’t capture it. In general, I noticed that this video card is characterized by flickering of objects when they are instantly loaded in some games, not only in The Witcher 3. For example, in Wolfenstein: New world order without ray tracing. This is much older game with same visible glitches.

Hello Roflosaur

Thank you for posting on the Intel® ARC™ Graphics Communites.

I see from your post you are using driver 31.0.101.4824, Have you checked if this issue happens on driver 31.0.101.4826? I would suggest uninstalling driver 31.0.101.4824 using Display Driver Uninstaller and updating to the latest version so we can discard a corrupted driver problem.

In case the issue still happens, let us know the distribution service the game was downloaded from (Steam, Epic, GOG).

Well, last driver fix issue wit DX:HR performance (from list of fixes), but for Witcher 3 seems like ray tracing is still artefacting.

Hello Roflosaur,

We understand that after running the DDU and updating the driver to version 31.0.101.4826, the raytracing issue persists. There is a new driver update that includes multiple fixes, and we would like to recommend you install our new driver 31.0.101.4885, and check if the issue persists with the latest fixes.

Best regards,

Install 31.0.101.4885, but not see the difference. There is need too look RTX behavior for comparing, I suppose. In the same game location. I just don't know what's normally for ray tracing for Witcher 3, because it's my first time experience with rays. But the advantage is still in favor of the classic render. In Cyberpunk 2077 rays looks fine, in Ratchet and Clank too, not counting the disappearance of glass near distant buildings at a certain angle.

Hello Roflosaur

We want to let you know that this issue regarding the popping/disappearing shadows when using raytracing should have been resolved on the game's latest version. Please update to the latest available version of the game and check if the issue persists or gets fixed for you. You might also want to update to our latest driver version 31.0.101.4972 but just updating the game should fix the problem.
