Comparisons to Rise of Flight

ROF was unplayable for me (just after release)..massive stutters etc....and is optimised pretty well today (with some graphical glitches above no mans land, flashing/flickering textures etc.) ......however I must admit that some folks had smooth gameplay right from the start....
Looks like I will need to pass through same "horror" again...its my destiny with sims I like, it seams....
