...well, here is a little thing about you guys who are waiting for dynamic weather and time of the day.
Sadly it is not going to happen (although I wish I was wrong, 'couse I'm the one waiting for that too).
Facts are simple, let's look at two games that have that. First one is FM7, on PC it runs OK, if you have OK PC, but on xBOne, it runs OK if there is no rain, if there is rain FPS drops to 30 (instead if 60). So there is big toll to be payed in order for xBOne to run rain etc. And worst of all, I know many won't say it is true, but FM7 doesn't have full day night cycle, it has only something like 2-3h of sun movement (where shadows stay same all the time), so it is not dynamic at all... And the rain, well there is rain, but how much does it affect cars... not so much. But feature is there...
Other game is ACC, and in order to run rain on that sim, you'll have to have really beefy PC, and I doubt it will be available on PS4/xBOne at all... maybe next gen... maybe...
In order to make day and night cycle on GTS, shaders, AF and many many other things need to be redone, and even if they've did that, game would look like **** (sorry for that word). And in order to run weather effects in the game, well, fps would for sure go down a lot. Look at one example we have in game, in missions you can drive a rally car in rain and... well everything is wet for sure, but there is no rain at all... so I really doubt that we will see dynamic weather effects at all... And why making static rainy day, it doesn't bring anything new to the game... you can simply put lower grip tires and have same effect...
We will probably have weather and day/night cycle on GT, but it won't be on PS4...
Simple as that... over a year and a half have passed and nothing is said about that at all... You really think it will come? I hope, but, as it is now, I doubt...
