do we have to abandon Spritekit ?

The issue continues to be the same with the latest BETA 26.4 released yesterday. I experience the same issue and I filed no I ticket with a similiar simple example code. The whole problem is very concerning for me - since the issues remains for months now - and I feel my Spritekit Indie project I was investing year now in danger

BETA 26.3 (2) (23D5103d) - does not fix the issue - the issue remains. My Spritekit App that runs smoothly on an very old iphone 6s (ios 15) with 60fps - is only running with 40fps or less (!) on BETA 26.3

Thats a bit frustrating. With BETA 26.3 the issue came back. My 100% Spritekit project that ran smooth with 60fps even on very old iphones - is now back stuttering , lagging at 40fps (iphone 13, ios 26.3)

Indeed I can confirm that 26.2 fixes the issue. Also for my (spritekit) project the framerate dropped from 60 to concerning 40 ... or even 30 on iphone13 - after installing 26.1 yesterday. the beta 26.2 fixes the issue (fortunately). now i am wondering when this update can be expected for normal users.
