Created attachment 62929 [details] Full CLI output with winedebug enabled
Kernel: 4.18.0-11-generic AMD Threadripper 2950x Nvidia GTX 1080TI w/ 396.54.09
Similar symptoms to OP. Launcher seems to work fine but hangs on the splash image after launch. I can confirm that the game starts up fine on my Intel based systems. I verified this by both swapping the SSD from the 2950x/1080TI system to the i5-6600k/GTX1080 system and also doing a clean Star Citizen install on the i7-8750H/GTX1070MAX-Q system.
Just a note if you're trying to help reproduce this, it has a lot of overlap with bug #46099 - similar symptom but different root cause as this issue predates that one on my system. Make sure you're using the patches from that bug when testing, or test with 3.17/3.18 before that bug was introduced.
If you're on Arch, you can use the patch set with the '_starcitizen_fix' variable set from this PKGBUILD: https://github.com/Tk-Glitch/PKGBUILDS/blob/master/wine-tkg-git/PKGBUILD
Or you could use either the RtlWaitOnAddress-race.patch (for wine master) or the starcitizen.patch (for wine staging) files in that same directory on github.
