Computer: RX 7900 XTX, i9-12900K, 32GB (2x16GB) DDR4-3600 CL14, Win 11 Pro 23H2 (latest build), Adrenalin 24.5.1 driver

Optimizing the game's performance for at least a smooth and steady 60 fps experience can be tricky for AMD Radeon (and Nvidia) users.

There is already an AMD Performance fix using DXVK Async layer with a few tweaks you may want to check too:

After some research and personal testing, I found an alternative performance fix without using Sporif's dxvk-async translation layer/patch. It only requires capping the framerate externally and some tweaks to in-game settings and display driver config (Adrenalin Software).

The tweaks are as follows:

• Use a reliable external third party (such as RivaTuner Statistic Server -RTSS-) or the in-driver framerate limiter and limit it to 60 FPS or your target achievable steady framerate.

• Force the in-driver V-Sync globally or in the driver game's profile (Wait for Vertical Refresh set to Always on). Alternatively, you can enable Radeon Enhanced Sync if you are using a high refresh rate (higher than 60 Hz) monitor and aiming to a steady high frame rate. Also, VRR/FreeSync is recommended.
  
• Enable Radeon AntiLag.

• Set in-game V-Sync off.
  
• Keep FPS uncapped in-game.
  
• Set the Object Quality setting to Low in-game (DO NOT use any other value).

After using these tweaks and settings, you should enjoy a smooth and steady 60 FPS experience. In my case, I had a 99% smooth and steady 60 FPS/Hz at 2160p, ultra settings (except Object Quality set to Low) using these tweaks. I hope it helps.
