Not the greatest performance with Unreal Tournament 3 under Wine (proton)

Unreal Tournament 3 works under Wine Proton 8.0 with FreeBSD 13.2-RELEASE-p4/5.
My main issue is that there are many times where the frame rate will drop to 20 or under when it shouldn't considering my hardware.
I have a Ryzen 5 3400G paired with an Nvidia GTX 1050.
My launcher is as follows:
env WINEPREFIX="/home/josh/.wine" env PROTON_NO_ESYNC=1 env PROTON_USE_D9VK=1 //usr/local/wine-proton/bin/wine "C:\\users\\josh\\AppData\\Roaming\\Microsoft\\Windows\\Start Menu\\Programs\\Unreal Tournament 3\\Unreal Tournament 3.lnk"
Have you installed separately dxvk? emulators/wine-proton is only a Wine version used by the Valve's Proton. All additional batteries must be installed manually. In that case, either download the precompiled library from the project on GitHub, or use emulators/winetricks for that.

Also, there are many other possible reasons for problems. You can try switch to pulseaudio as the sound system, different version of Wine, etc. Sometimes altering system configuration helps too.
