Absolutely not unfounded. ;-)
The specification of my computer absolutely does not allow me to enjoy the benefits of XP12 using IXEG in VR mode (that's the only way I fly).
In XP11, with all the additions and "improvers", it achieves a completely smooth VR simulation in any region, in any weather conditions.
I have an XP12 and I am fully aware of its superiority over the XP11, but I have no pleasure in flying it.
If I upgrade my computer, I will definitely switch 100% to XP12, but for now, the VR mode in XP12 is very lame.
And still if I want to fly IXEG, I fly in XP11....
