Since Total War: Shogun 2 was recently ported to Linux, I decided to install it on my laptop running Arch Linux which has an integrated Intel graphics card (Intel HD 5500) as well as an additional NVIDIA card (NVIDIA GForce 940M), which are setup using bumblebee. However, when starting the game using
primusrun, the game doesn't actually seem to use the dedicated card (entering the video settings in-game shows me that the Intel card is used). Upon researching further, I found out that the game uses a shellscript named
Shogun2.sh to launch itself, and sure enough, running
fuser -v /usr/lib/primus/libGL.so.1 shows that
Shogun2.sh has actually loaded the
libGl.so.1 from primusrun, but this doesn't seem to extend to the actual binary. Then again, running
tr \\0 \\n < /proc/8044/environ (where 8044 is the PID of the binary) shows that
/usr/$LIB/primus is actually a part of
I have tried inserting the
primusrun command into the shellscript so that the binary is executed through it, but to no success.
Another method I thought about was using the "Advanced options" field in the Feral launcher that seems to be baked into the binary and seems to be required to launch the game, but I was unable to find any documentation on supported switches/syntax.
Is there any way to enable the dedicated GPU for Shogun 2: Total War on linux?
