I think LM have done a very good job. 5.2.22 (HF) has rectified a lot of small and irritating issues and repaired and adjusted others. So no need now for Shader fixes or Cloud Addons - they have basically nailed it now. Menu's and view change selections are smooth and trouble free and basically with most sliders on ULTRA - the sim is smooth and predictable.
This is now a very impressive flight simulator and I am not sure what one could possibly change with high quality LC or textures (Such as ORBX) Stock Shaders, EA and True Sky (Plus NIVIDIA's ocean and wave motion capacity) I can run a highly complex study level aircraft or the most basic of aeroplanes or one that likes to be on the water now and then (DC-9-30 v Piper Cub v Floatplane) without any issues or problems.
I have always hoped that we would finally get a high level simulator with superb graphics and performance and a fair degree of addon flexibility, LM appear to have done it - 9/10 from me!
I am sure some folk will find something to complain about but I can't.
