PC
Note: Since launch, we are continuously making improvements to the game and will keep rolling out these patches. We are also actively working with NVIDIA on specific issues that some users have reported with performance degrading over time. With the latest 1.3.3 patch, we've added NVIDIA DLSS, which significantly improves framerate while maintaining high quality visuals for NVIDIA RTX hardware. We've also added DLSS support for ultra performance mode and Dynamic Resolution scaling. More information about NVIDIA DLSS can be found here.
