Found something interesting!
I load the config from post #7 on WinUAE 3.0.0, start the emu with Alien-Scoopex demo in FD0 and immediately save state file when WB screen showed.
Now I load the config from post #7 on WinUAE 3.5.0 and load that saved state file... max CPU usage at "inside of torus rotation" part is now 96-97% instead of 114% !
I tryed same with savestate file from WinUAE 2.8.0 and got same 96-97% result in WinUAE 3.5.0 !
So, when WinUAE 3.5.0 is started with config from post #7 it give 114% and when is started + savestate file from WinUAE 2.8.0/3.0.0 it will give 96-97% !

Note: After every test the emu was quit, started again, loaded with same config file, loaded with next state file and run!

This 4M+ cache is not L2 cache! On "modern" laptop PCs L2 cache is 512KB or 1024KB and slower L3 cache is 4M+ but shared with other cores!
Also, with high resolutions + integrated gfx cards the bandwidth of DDR4 2333 RAM may drop drastically.
