Hi Community,

i played Witcher 2 a few years ago on an i5 / 8 GB DDR3 / GTX 1060 - Windows 10 with:
40-60 FPS with everything on max but without Über-Sampling.

Now i tried to play the game again, this time not on the side of the Scoyatel.

System today:
Ryzen 5 1500X / 32 GB DDR4 / GTX 1060 - Windows 11 with:
15-25 FPS the moment i leave Triss tent, with everything on max but without Über-Sampling.

And the strange thing is, it doesn't matter which settings i choose. Lowest or highest (1080p) the result is always the same?! What the... !?

I reinstalled the Crapvidia driver, complete deinstallation and then fresh new install. I completely deleted every old Witcher config but the result is always the same.
I already set the user.ini TextureMemoryBudget=6144, fitting my GTX 1060 specs. Nothing helps.
Trying DXVK (in Windows) won't change anything too.

And to enter the zone were normal things don't happen very often completly. When i install Witcher 2 (Windows Version) under my Linux on the other drive (Fedora 42 / KDE / Proton GE 10-3) and use the same max settings i use under Windows 11, i get out nearly constant 60 FPS, no matter whats happening on the screen.

Is there some kind of heavy problem with The Witcher 2 and Windows 11 ?! Does somebody here know a solution?

Edit: Steam Version shows the same behavior under Windows 11

Found a "solution".

First problem, the first part of the games prologue always suffers a heavy perfomance loss. Regardless of the settings.

But for the following parts of the game, changing the TextureMemoryBudget in user.ini solved the problem for me.
Beginning at 1500 up to the max for my hardware (6144).

The FPS is now jumping around between 40-60 FPS,

Changes through the settings menu will revert the manual change of the TextureMemoryBudget!
