Have you tried no dense scenery, no weather, no nav-aids, no routes and anything else … no flight information, approach guides, landmarks, interactive cockpit, advanced view movement, reduced frame rates off, ‘assistance’ and that ‘co-pilot’?

My Sony Xperia I phone needs reduced frame rates and medium graphics in Android, it was a hot phone until 2023!
