The Sim Update 5 has been released yesterday.
For Steam users, you first need to download a first update from Steam, size is 350 MB.
Then you launch the sim, and it will download the actual Sim Update. The size varies depending on which version of the sim you have (standard, premium etc...).
I have the standard version and the Sim Update 5 size was 40 GB.
The servers are currently overloaded a bit, so I would recommend you to wait a day or two before trying to update, if you're not in a hurry.
Also, keep in mind that after installing that SimUpdate 5, you will need to go into the content manager in the sim, and download some updated versions of the previous "World Updates" (Japan, UK, US etc...) that you might have installed in the past. These updates are approx 5~6 GB in size each.
From my side I was lucky and the install went well without problems.
I could test the sim yesterday to see the results. I had to re-adjust a few of my settings. My controller settings were kind of default so no issues for me, but I know some simmers had to re-configure their axis settings in the sim.
For info, my computer is equipped with an Intel i7 8700k coupled with an NVidia GTX 1070-ti, running on Windows 10.
In 2D mode, I have quite a nice FPS improvement. Around my local airport LFMN, I used to get around 40 to 45 FPS in average. I'm not getting number close to 60 FPS.
In VR my FPS gain was smaller. My video card is too old for a miracle on that side. Nevertheless I did get additional smoothness that allowed me to increase the render scale a little bit.
A quick summary of the various info I collected on other forums, from user feedbacks:
- It is STRONGLY recommended to empty your "Community" folder before applying the Sim Update 5. Changes brought by that update are too deep and many addons are totally incompatible. This could even prevent the sim from loading. You'll have to wait for these addons to be officially updated by their creators for SU5 compatibility.
- The Live AI traffic is currently causing crashes to desktop (CTD) for many users. It is recommended to leave the AI traffic OFF.
- The sim now 'unloads" the ground objects which are not on screen, and needs to reload them when they come in the screen. That means that when panning the view very fast, some popping of ground objects can happen. On my computer this is quite limited and hard to spot (and not visible at all in VR) , but for some users this is very annoying.
