Star Citizen 3.16 - Testing PCIe Gen 4 SSD at New Babbage at 4K

Quick comparison benchmark test of the 1TB Western Digital WD_BLACK™ SN850 NVMe™ SSD with 7000MB/s read speed and 5300MB/s write speeds.

The comparison is against the Crucial MX500 1TB 3D NAND SATA 2.5 Inch Internal SSD, up to 560MB/s

As expected there are performance gains in terms of both frame rates and frame times to be had by using the NVMe drive due to the faster read speeds.

NOTE: I lose about 7-10fps from capturing the footage with lib.x264 encoder.

Once Lutris is installed, install SC from Lutris script

Lug-Helper

Run pre-flight checks using Lug-helper either from
GitHub: https://github.com/starcitizen-lug/lug-helper
or
Arch AUR: https://aur.archlinux.org/packages/lug-helper/

Once SC is installed you can use the LUG WINE runners from
DevNull:

NOTE FSYNC COMPATIBLE KERNEL REQUIRED:
Ubuntu/elementary OS/Pop!_OS users can check out XanMod for an fsync compatible kernel

======================================================
Increase the sysctl option vm.max_map_count to prevent
crashes due to memory allocation limits in areas with
lots of geometry:
Note I am running at 4K on 64GB RAM so my setting is 2100000000
For anyone running 1440p or 1080p with upto 32GB RAM use 16777216

sudo nano /etc/sysctl.conf
enter the sysctl option vm.max_map_count

vm.max_map_count = 2100000000

sudo nano /etc/sysctl.d/20-max_map_count.conf
enter the sysctl option vm.max_map_count to prevent crashes
due to memory allocation limits in areas with lots of geometry
vm.max_map_count = 2100000000

sudo nano /etc/systemd/system.conf
delete # from the line "DefaultLimitNOFILE" and set value to
DefaultLimitNOFILE=2100000000

sudo nano /etc/systemd/user.conf
delete # from the line "DefaultLimitNOFILE" and set value to
DefaultLimitNOFILE=2100000000

To temporarily increase this value enter this command in a terminal
sudo sysctl -w vm.max_map_count=2100000000

Output: vm.max_map_count = 2100000000

more /etc/systemd/system.conf | grep NOFILE

======================================================
Finally, to make sure your system is not starving Star Citizen of RAM,
you may want to change your "vm.swappiness" to 10.

The default is 60 meaning tthat your kernel will swap when RAM reaches
40% capacity. Setting it to “100” means that your kernel will try to
swap everything. Setting it to 10 (like I did on this tutorial) means
that swap will be used when RAM is 90% full, so if you have enough RAM memory,
this could be a safe option that would easily improve the performance of
your system.

To temprarily set vm.swappiness=10 do the following in the terminal:

sudo sysctl vm.swappiness=10

and enter the following to confirm the changes took hold

cat /proc/sys/vm/swappiness

For more permanent sollution simply open your "/etc/sysctl.conf" file from earlier
and add the line

vm.swappiness=10
