The newly added check for HasTemporalUpscaleView() runs in 4.26 before any views are added to the ViewFamily

[soulsource]

In the latest version (3.1.0) a new check has been added that prevents the setup of XeSS-SR for ViewFamilies that don't have any Temporal-AA views.

The problem is that at least in 4.26 this check is being run before the views are created, and therefore fails unconditionally. Namely, the checks run when UGameViewportClient::Draw() calls GCustomStaticScreenPercentage->SetupmainGameViewFamily(), what is done a couple of lines before the calls to LocalPlayer->CalcSceneView(), which create the views.

Thank you so much for your feedback, we'll investigate the issue and try to fix it in the coming release soon.

The issue has been confirmed and Unreal Engine 4.26, 4.27, 5.0 are affected, we'll disable the checking for these Engine versions and strengthen our automation test.
