Perhaps will be useful to someone else who mad enough to run Freelancer on Linux (i'm using arch, btw).
So as been said, tested on Arch Linux with wine staging 6.16: works fine, aside of odd FPS drops every ~15 seconds (see screenshot for FPS graph and another for (h)top output) everything went smooth -- I had wine mono and gecko installed and launched DLauncher without issue but used it only for switching profiles. Freelancer.exe launched without issue as expected. Considering a single core double thread APU (AMD A4-4300M) I utilise - most likely hardware to blame.
In winetricks had installed the following packages: amstream, d3dx9_24 > d3dx9_43 (not sure if necessary, but guide on WineHQ had them listed), d3dx9, devenum, directplay (required for multiplayer, as far as I know), dotnet40, mfc42, msacm32, quartz_feb10.
^ Issue was in the prefix version's and lack of CPU. On older prefix cpu was not that bloated so lesser drops.
The server IP has been updated to 95.217.88.9:2302, thus replace -s163.172.117.137:2302 to -s95.217.88.9:2302.
p.s. Lutris script was failing (no_file_provided error) the installation after the discovery itself been installed. Didn't find the reason yet, but if someone will - please share/submit the fix.
