It seems Clustertruck has high demanding graphics requirements (not given in GOG product page;
see my forum contribution to Filament: "Game needs conformant Vulkan (AMD Navi means Mesa 20.0+)").
If not met, selecting the stage and starting [i.e. Play - Campaign - Play - {stuck}] results in emerging noise of the game while still seeing the selection screen - but with changed color palette and blooming effects ...
On AMD Navi 10 (aka AMD Radeon RX 5700 XT; used with AMD Zen 2: Ryzen 5 3600) I had to use
for Kubuntu Focal (20.04.0 LTS) Linux 5.6-oem from `Ubuntu Test Kernel' PPA:
* https://launchpad.net/%7Ecanonical-kernel-team/+archive/ubuntu/ppa/+index?batch=75&memo=150&start=150 ,
on Kubuntu Bionic (18.04.4 LTS HWE) and Xubuntu Eoan (19.10 STS) I used Linux 5.7.6 from Vanilla kernel PPA:
* [url=https://kernel.ubuntu.com/~kernel-ppa/mainline]https://kernel.ubuntu.com/~kernel-ppa/mainline[/url]
and Mesa 20.1.2 (which can also be used on Focal 20.04.0) from `Mesa Almost Stable' PPA:
* [url=https://launchpad.net/~ernstp/+archive/ubuntu/mesarc]https://launchpad.net/~ernstp/+archive/ubuntu/mesarc[/url]
to make it run.
On Haswell with iGPU I saw the same problems ... but in this case it is not a driver problem ...
so that HW is not fulfilling the minimum requirements (whatever those may be ...).
I thought Clustertruck had been a 32 bit game (with formerly giving needed 32 bit libs for Linux).
But maybe I am wrong.
It is now a 64 bit binary only for Linux (which is OK, of cause) and looks quite current (using Unity).
On Navi 10 with current drivers (not in Ubuntu distros right now) it is really nice ... but a game of 2016
should work on Haswell - and the GOG specification for HW is easily met ... without fulfilling the real one.
So GOG should give the minimum requirement for the current game correctly to help their customers.
This should only be a technical heads up - especially for Navi 10 gamers on Linux incl. specified PPAs one may use to play - but be warned - this is no longer a supported Ubuntu platform (but with Navi there is no supported Ubuntu platform available yet - thus it is OK ;).
First well working Ubuntu will be Groovy Gorilla (20.10 STS) which will also not be blessed with support by GOG ... so it will be that HWE stack backported to Focal (i.e. 20.04.2 LTS HWE) which gives the 1st possible supported platform for AMD Navi (and hopefully the package problems and other difficulties with programs may be solved till then ...).
But only if GOG will support that Ubuntu 20.04 LTS in the future ... we will see ...
