Getting rather low fps on andoid Galaxy Tab S8 ultra with the startup sphere

new nomad version 1.91 40 fps

old nomad version 1.90 120 fps
nomad - WebAssembly (/demo) 60 fps
nomad - WebAssembly (older /demo2) 120 fps

gpu load is 70% for all, cpu 30%. used gpuwatch to see fps

let me know if there’s anything I could investigate

gotten better with 1.92, but still not the performance numbers of 1.90 or the older 1.91 webdemo from April

Tablet S8 Ultra
version 1.92 ** 57 fps **
nomad - WebAssembly (/demo 1.92) 57 fps
nomad - WebAssembly (older /demo2 from April 25 2024) ** 121 fps **

Tablet S7+
nomad - WebAssembly (/demo 1.92) 87 fps (probably because of lower resolution)
nomad - WebAssembly (older /demo2 from April 25 2024) 120 fps

Windows
nomad - WebAssembly (/demo 1.92) – not working – shows the sphere shortly then the sphere disappears
nomad - WebAssembly (older /demo2 from April 25 2024) 120 fps

57 fps would be ok to work with of course just seeing it can do so much better

standard startup scene with the sphere, no post fx added

Ok reverted to an older version, then reinstalled the new version, now it’s fast at 120 fps! Probably there was another 1.92 update meanwhile, or the reinstall fixed it somehow (unlikely though) Thanks in any case.

I know it’s annoying, but just one more thing about android, at the moment it crashes every 2nd time I start it - I think the cycle is: it goes to some kind of background mode that it can’t properly wake up from, and when i try it exits fully so it starts normally the next time (Same thing happened around a year ago, then it was fixed, but now it’s back)

Happens only on the Tab s8 ultra in Dex mode though. Normal mode and on the s7+ (both Dex and Normal mode) works fine!

In today’s android 1.92 update, the crash issue has changed but it’s still happening when coming back from stopped mode (I called it “background mode” in my last post but I think it’s actually “stopped mode” where memory contents are cached or something)

So as usual in Dex every 2nd time it’s started, but also happening in normal mode now when it’s stopped, for example when switching user to guest and back. Background mode is working fine for both Dex and normal.

It happens after moving the camera for a few seconds. Without moving the camera, there’s no crash. Also it happens on the tab S8 ultra only, not on the S7+.

The crash was different in the last version, before today, it crashed immediately from stopped mode. Interestingly only when the window width was > its height.

in case this is gettting too annoying :grimacing: It’s only an inconvenience btw. Starting the app for a second time is no problem.

I shoud’ve started a new thread for this issue… anyway some more info

The crash happens exactly when removing all fingers for the first time after starting the app (from stopped mode). So i can do exactly 1 brush stroke/1 camera movement before it happens.

maybe this helps
