How do I enable slow animation in iOS simulator?

In the iOS simulator, at the bar on the top, click on Debug → Toggle Slow Animations (or Slow Animations with Xcode 10+). Chances are you accidentally toggled it on. Show activity on this post.

Why is my network connection so slow on simulator?

Now you can run your app on Simulator and its network connection would be very very slow. Please be reminded that it is affecting your Mac’s network connection. If you’re running your backend server on the same Mac, it’s still fast because it doesn’t affect localhost. Also, remember to turn it off AFTER finishing your testing.

Why can’t I run Farming Simulator 22?

A good first step is to check the system requirements for the game. The game’s minimum requirements are: There are a few things you could try: Close other programs (especially CPU and RAM heavy programs like web browsers). Give Farming Simulator 22 High priority via task manager.

How do I enable high priority mode in Farming Simulator 22?

2) Open Task Manager [CTRL+SHIFT+ESC]. 3) Switch it to the More details view if required using the “More Details” link in the bottom right corner. 4) Switch to the “Details” tab. 5) Right click “Farming Simulator 22.exe” on the list -> “Set priority” -> “High”.

iOS Simulator games run very slow (low fps)

The Simulator is not a device. The Simulator uses the Mac's CPU (tons faster) and the Mac's memory (lots more). However the Simulator also emulates OpenGL ES via a software renderer, which is abysmally slow even on the fastest CPU.

Because of this and the fact that no end user will ever run an app on the Simulator, any performance measurements on the Simulator are utterly IRRELEVANT!

Sorry for shouting but I felt this needed to be said with conviction. ;)

Even though this post is almost 8 years old I found myself in the same situation when trying to record an App Store preview for my Unity game.

With your simulator open you can change the GPU Selection to improve performance. It was set to Automatic for me and changing it to Prefer Discrete GPU dramatically improved the frame rate.

Notes

Tested with Xcode 12.5 - not sure when this feature was introduced.
I had to restart the simulator for it to take effect.
Your Mac will presumably need to have a discrete GPU in the first place (mine is a 15" MacBook Pro).
