TechPowerUp writes users can expect a performance uplift of up to 50 percent. This will not be the end of RTX performance optimization, more updates are expected:
NVIDIA has been closely working with EA-DICE on this new patch, which NVIDIA claims improves the game's frame-rates with DXR enabled by "up to 50 percent." The patch enables RTX 2080 Ti users to smoothly play "Battlefield V" with DXR at 1440p resolution, with frame-rates over 60 fps, and DXR Reflections set to "Ultra." RTX 2080 (non-Ti) users should be able to play the game at 1440p with over 60 fps, if the DXR Reflections toggle is set at "Medium." RTX 2070 users can play the game at 1080p, with over 60 fps, and the toggle set to "Medium." NVIDIA states that it is continuing to work with DICE to improve DXR performance even further, which will take the shape of future game patches and driver updates.
