The game was playable in the starting area but once I got to the void is became almost unplayable. The framerate is very low and even when it was playable I was getting sub 25fps with stuttering when the game loaded assets. the further I got into the game during my first 1-2 hour play session it got worse.
It occasionally starts running better after I stutter around the map and seemingly load the extra textures.
System details below.
Ubuntu 20.04 (stock and updated)
Mate window manager 1.24.0
Native Linux client installed from Steam
GTX960 running 440.64 proprietary
Temps reach 62c max on GPU
GPU Utilization between 25 and 95%
Intel 3930k
CPU utilization 75% to 100% on 1 core
Govenor set to performance
CPU temps never over 70c (rated to ~94c before it would go into protect mode and slow the clock)
Looks to be only using one core but jumps a lot from core to core
16gig RAM
Uses between 9 and 11 gigabytes of RAM!!
Textures set to very low
Medium brightness
Maximized Window
Resolution set to 1920x1080 but tried lower resolutions and this had no percieable impact.
Vertical Sync on and off (no difference)
Antialiasing off
Shadow quality very low
Grass density off
Reflections very low
Ambient Occlusion very low
Screen Space Reflections very low
Terrain Quality very low
Bloom off
I have tried just about every combo I could think of and used some suggested settings I found posted in other threads. I can play other games on near full quality at 1920x1080 with no issues and even windows games using proton through Steam or installed with wine seem to blow this game out of the water when it comes to performance.
The game looks like it will be amazing but I cant play it like this and I just spent $35 on it.
Any help would be much appreciated.
