I am developing a VR mobile racing game for android devices with Unity 2017.3. I have followed all the advices on improving performance that are listed here: VR Best Practice - Unity Learn , but after my mobile device automatically updated the firmware two days ago, the performance now gets pretty bad in terms of FPS, after a few seconds running.
I really don’t know what to do. I have searched for similar issues on other topics but didn’t find anything. Last week the same .exe was running perfect. Now, without changing anything, it’s almost impossible to play.
I would appreciate any kind of hints or help! Tomorrow is the launching day.
It’s been a re-occurring problem for me as well on mobile. I left vSync on and didn’t set the target frame rate with a script. Sometimes I get it working by completely uninstalling the app from the phone and then building and running it. Your issue could be different from mine though, so I would recommend downloading the memory profiler by Unity: https://bitbucket.org/Unity-Technologies/memoryprofiler/overview
You just drop the files into your project’s root folder (if there are any files with the same name SKIP them. Do not replace) then open it in Unity from the Window tab. It helped me find a few sprites that had a high import size which was forcing unity to resize them and waste a lot memory.
