Hi Tim 767
I'm not with Laminar Research, just a fellow simmer in the UK, but could you please confirm what type of 'crash' you mean?
1. X-Plane 11 crash back to desktop (CTD)
2. Total PC crash to blue screen of death (BSOD)
Any such crash could be software related, but could more often be hardware related.
Please therefore could you confirm the specification of your PC:-
1. CPU - central processor unit
2. GPU - graphic processor
3. PSU - power supply unit wattage
4. RAM memory
I'm simply trying to establish if your PC meets the minimum specification requirements as per the following webpage: https://www.x-plane.com/kb/x-plane-11-system-requirements/
