Warframe running at Low FPS on High end hardware, no sound

Hey,
So I recently started running Warframe using the latest custom Proton patch by GloriousEggroll. I noticed, however, every time I boot into the game, it runs at crazy low FPS and there's no sound. It appears no messing around with the settings fixes it, and no other Proton patches fixes it either. Is there a driver I need to fix somewhere maybe?
Here are my specs:
Operating System: Manjaro Linux
KDE Plasma Version: 5.18.3
KDE Frameworks Version: 5.68.0
Qt Version: 5.14.1
Kernel Version: 5.5.11-1-MANJARO
OS Type: 64-bit
Processors: 6 × Intel® Core™ i5-8600K CPU @ 3.60GHz
Memory: 15.6 GiB of RAM
GPU: AMD Radeon Vega64

Any help is appreciated. I am addicted to this game and I need my fix ASAP

Hello there, can you mention what you have tried?

I played with most of the settings... DX10 instead of 11, all the launcher settings, vsync, and most of the graphical settings. Setting them all to low and then high and medium... Nothing.

As for proton patches, Proton5.4-GE-1 thru 3, normal 5.0.4 and Native Steam.

Have you tried adding some of the launch flags suggested there?

I have. All of them. Specifically:

DRI_PRIME=1 PROTON_USE_WINED3D=1 PROTON_NO_ESYNC=1 WINEDLLOVERRIDES="xaudio2_7=n,b" RADV_PERFTEST=aco %command%

And all they did was make my launcher display no graphics, lol. I even installed xboxdrv, to no effect.
