DRS (dynamic resolution) for PC

[cybernesis07]

From the demo, I noticed that the game has very inconsistent FPS. I'm playing on high settings with the FSR Balanced preset and a 4K target resolution on a Ryzen 7800X3D and Radeon RX 7800XT. And depending on the scene, I get anywhere from 40 to 90 FPS. Are there any chances of implementing a dynamic resolution system for PC in future updates to smooth out these fluctuations? I would really prefer not to drop resolution to 1080p everywhere.
And what about FSR 3.1 with frame generation for non-Nvidia GPU owners?
