There was a regression between Wine 6.22 and 6.23 that caused a FPS performance
drop in Vanilla WoW 1.12.1 client (Nostalrius client, played on
https://darrowshire.com).

This regression is still present in 7.04c4. The FPS is almost double the value
in 6.22 compared to 6.23 or 7.0rc4.

Pure Wine installation, my OS is Arch Linux 5.10.88 with nvidia 495.46
proprietary drivers with Openbox WM.

Here are a few screenshot for comparison:
