WOW, what a can of worms.

As usual I start with the websites of the actual game, sometimes this can give hints as to the issue(s) that might have to be fixed.

In this case, I only found a list of requirements that needed to be installed.

* quartz qedit devenum wmp9 physx (plus an extra decoder)

When starting for the first time, it turns out that "physx", is the only requirement to get to the actual launcher.

Boom, a crash caused by failure to allocate memory, in quartz and d3d. On startup, was it really trying to allocate more than 3GB of memory. Rumors have it that some games actual try at allocated more memory than they should and windows some hows handles it without issues, sometimes. Things you learn on the way.

All the logs I generated pointed to some sort of memory corruption/exhaustion. At this stage logs alone were not going to give to much of clue. More investigation was going be required.

Then a surprise, after a daily rebase of staging, it worked without issues. After checking that my PREFIX was clean, it was time to workout exactly what changed. It was easy enough to spot, a fix in quartz (listed below), which stops glibc memory corruption and X errors.
