Just to keep it short. This games runs terrible on my hardware. I have a modern PC with Windows 10 as OS.

AMD Ryzen 5 2600
AMD RX 5700
16GB DDR4 3200Mhz

I'm running the latest drives and updates.

When I check what is causing the bad performance it looks like possible a driver issue from AMD. The card is under utilised and runs only ar 40 to 50% with clockspeeds far lower can the normal game clockspeeds (500-900 vs 1700Mhz). With this utilisation I only get 20~40 frames in first opening level (where you shoot the Trebuchet).

Don't give me an answer to turn of SuperSampling, that is not causing this behaviour.

What can I do? This is gamebreaking performance.

I have the same comp, and the same issues. Haven't found a workaround yet..

Found that, it might give some clues?

In general i think many people are having issue with AMD's latest cards, and it seems to be driver related much of the time.

Hi everyone! I've found that after CDPR updated Witcher 2 for MAC it crashed the Windows version. So I got version 1.3 made before the update and it works just fine! Hope that helps.

How did you get the 1.3 version? It seems I can't choose which version to download in GOG library.

You should be able to do this with GOG Galaxy and its rollback feature.
