you are still comparing real vs virtual and IMO they are different , a virtual world will also make you dizzy . well as I said i am not technically qualified as to what fps an eye needs to see clean / clear / smooth / jerk less motion. Do realize we are playing with real time object creation. in a real world they already exist. here it is the computer world which needs to create it every time the same or maybe different objects and scenarios hence we run after having more fps that means that your comp needs to be super quick. As I said this is my opinion. You are free to comment though. Simply put it, you don't like the scenery or the tool you are free not to use it. no offence or anything intended towards you. I come from FSX and i know that fps is essential , there FSX is a good example. why not try a flight around the heaviest area having OSM data using W2XP and keep the settings to the max and see what you are achieving , every computer will behave differently even though they may have a similar config. Seriously just try it and fly around , take some flights around zurich / geneva and see how it feels and if you haven't flown in Switzerland in XPX with the HD Mesh and the photo scenery and W2XP then let me tell you that you are missing something, its beautiful, or better yet fly from Schiphol towards Seppe South West as Netherlands is pretty heavy on the comp. One thing I would like to say this is what i wanted in a simulator the real world objects or object placements and here it is. Don't go too much on the object models and textures as I think in the future they will start getting matured enough. But still they look very very nice. Fly man.
