It's a shame they don't officially support OSS drivers despite them running X-Plane better. All this contributes to driver separation, confusion, and Linux still being regarded as "not ready for quite a few games". BTW, if you happen to run OSS drivers and wanna try X-Plane, be it v10 or v11, set a launch command (could be on Steam too) to: --no_pinned This does get rid of the crashes, which are observable when e.g. clouds are enabled.
