As we’ve already reported, The Witcher 3 Next-Gen currently suffers from some awful CPU optimization issues. These CPU optimization issues surface when players enable the game’s Ray Tracing effects. And, due to these issues, there is currently no CPU that can run The Witcher 3 Next-Gen RT with constant 60fps.
A new mod for the game surfaced earlier this month, promising to improve performance when using RTGI. At first glance, this mod looks interesting.
However, and after testing it, the mod does not bring any performance improvements in CPU-bound scenes. So yeah, no wonder the comparison video is in the open-world area and not in a city. Thus, and while you may get some performance improvements in the rare GPU-bound scenarios, you will be still dropping below 60fps in CPU-heavy scenes.
So, is there any way to get constant 60fps in The Witcher 3 Next-Gen with Ray Tracing? Well, actually there is. However, this “workaround” is only available to those owning an RTX40 series GPU.
By using DLSS 3 (which the game supports natively), you can double your in-game performance. As such, and even on an Intel i9 9900K, you can get constant 60fps. We’ve said it before and we’ll say it again; DLSS 3 is a godsend for games that are CPU-bound. Furthermore, most of you won’t be able to notice – in this particular game – the additional input latency introduced by it.
Below you can find some comparisons between native 1440p without DLSS 3 Frame Generation (left) and with DLSS 3 Frame Generation (right). In order to capture these screenshots, we used an Intel i9 9900K with an NVIDIA GeForce RTX4090 and 16GB of DDR4.
In conclusion, and while we appreciate modders, there is no mod that can improve the game’s RT performance in cities. The only way to overcome the game’s CPU optimization issues is to use DLSS 3. At least for now.
