This applies to the GTX 10
line
The game Alan Wake 2 is one of the most demanding at the moment and the first that conditionally does not work at all on older video cards, and the point is not at all in ray tracing. However, the developers from Remedy have prepared a patch that greatly improves performance on older video cards.
The preliminary version of the patch has already been tested by Digital Foundry specialists. Judging by their review, the patch improves performance only on video cards of the GeForce GTX 10 line, but this is very good news, because, judging by Steam statistics, there are still a lot of owners of such video cards.
The authors tested the game in Full HD with settings roughly equivalent to those of the PlayStation 5, including active FSR 2 technology in Quality mode. As you can see, the patch greatly improves performance. GTX 10 cards began to work faster by anywhere from 50% and up to 100-200%, depending on the location. As a result, even the GTX 1060 produces a little more than 25 fps, however, in the forest, where the load is lower than, for example, in the city. The GTX 1080 Ti, in turn, allows you to get the almost coveted 60 fps.
True, testing was carried out with top AMD and Intel processors, and GTX 10 owners clearly mostly use much less powerful solutions, so it is unclear how playable Alan Wake 2 will be after the patch on the GTX 1060 or GTX 1070 in the case of some conditional Core i5-7500.
In any case, considering that the root of the performance problem on older cards lay in the mesh shaders, it is surprising that Remedy was able to somehow solve this issue at all.
It remains to add that the same patch will become available to everyone on March 6th.
