My system:
CPU, AMD FX-8370
GPU, Sapphire HD7970 (r9-280)
MOBO, GA-990fxa-Ud7 rev 1.0
RAM: Corsair Vengeance 16Gb 1866Mhz
Drives: Multiple SSDs in RAID5 clusters on a LSI MegaRAID controller
O.S., Pop!OS (Ubuntu 18.04.3 LTS)
Kernel, 4.15.0-20-generic
OpenGl version 4.5
Mesa 19.1.4
1920 x 1080 60Hz monitor

The system seems to meet requirements, but I get abysmal performance and FPS bouncing everywhere.
I had to lower resolution and graphic until the game looks horrible to get passed the 30fps average...
The GPU can run similar games at epic resolutions with a steady 60fps (Vsync) normally.
Could it be due to the fact that 3Gb VRAM is on the low side for this game?

Haven't tried it under Windows, and don't really plan to unless forced to...

Thanks for your help :)

Are you running it natively or emulated? According to the developer, the emulated Windows version has a better performance:
For whatever reason I don't understand (only Epic, the makers of the Engine, will know) the game runs much slower on Linux. But running the windows version via an emulator gives people great performance. So either way this is the better option. I would rather not give you a version that is inferior for reasons I cannot change.

I am guessing that you mean running the windows version through WINE (which is not an emulator, but rather an interpreter/translator for Windows programs).
I will give it a try and report how it goes...

If it does in fact get rid of the issue, it would mean that Epic is the worst software developer out there! How can a native Vulkan game run so poorly on Linux... Normally, Vulkan API flies under Linux!

I never knew WINE is not an emulator, although even the name says it... ouch xD

But good luck, hope you can enjoy it!

Known issue with the Unreal engine under Linux. And yes, it sucks.

Well on my machine it runs stable at the max and does not drop FPS, but still annoying that it does not deliver more FPS.
