Game is using only 2 of 6 physical cores, up to 5 after adding lunch options.
My rig:
Workstation Laptop Dell Precission 7530
Xeon E-2176M 2,7 GHz (6 core) 4,40 GHz in Turbo mode
32 GB Ram DDR4
2x SSD
Nvidia Quadro P3200 6 GB Ram
Driver 582.41 (newest)
1080p
Windows 10 64bit
Hello. Game is using only 2 out of 6 physical cores by default. After adding -useallavailablecores in lunch parameters it is using all 12 during loading and max 5 during gameplay. This results in lower fps in the game. For comparison SE1 is using all of my 12 cores. I made some pics with MSI afterburner monitor. You can find them here or as attachment.
Here are the pictures with difrent settings and all the numbers i was able to show on screen:
Planet
Space
SE1 on planet
Here You can see how the game is using the hardware better than in SE2
after adding the lunch parameter in SE2:
As You see it uses more at once but far from 100%. I only hit 100% of all cores after setting High preset in graphical settings. In other cases its more or less as You see on the screens.
Wish You the best
Jaroslaw
