Same here, with my settings that aim for 36 baseline FPS with frame generation on to get 72FPS, I have no issues to maintain those 72FPS with the PMDG 777, while with the Ini A350, I struggle to get above 70FPS on many airports. Put it on a default airport with clear skies and no AI traffic, then yes, the performance is fine. Put it on a big addon airport with AI traffic, and the 350 shows considerably 20FPS less than the PMDG 777 when running unlimited FPS. And yes, I am already using the low res textures and the performance mode. It is a ressource hog...
