I have "Disable Copy to EFB" and "Enable EFB To Texture" - wich one did u mean?
And do you mean with JITIL the "Unlimited Jit Cache" Function?
Edit: Ah sorry, always running in JITIL because its crashing permanently and isnt playable without.
Edit: Enabled both Options (so disabled copy to EFB

) but same Problem AND no Cars anymore.
Thanks anyway. =/
Edit:
Tested in Practice with 29 CPUs.
Rubin Cub:
Mute City - Good
Casino Palace - Good
Sand Ocean - Horrible (FPS arround ~3-5, dont know later i dont have fun to test a later Part of the Track)
Lightning - Good but after a while it Crashes - to bad its a cool one

(GFX FIFO: Unkown Opcode (0x3f) + some other Codes in a second Warning)
Aeropolis - Good with minor Slowdowns at the Start (think the Playerfield in Front of me)
Saphir Cub:
Big Blue - Runs "okay", many Slowdowns inside of the Tunnels on some Places
Port Town - Good with some minor Slow Downs
Green Plant - Many Slowdowns but its "okay" ...
Port Town (Pipe) - Ahhh a Pipe without Slowdowns ...

Mute City - Good but then Dolphin Freezes with Soundloop (no Error)
Smaragd Cub:
Fire Field - Good
Green Plant - Horrible! Maybe some Areas (realy short) with better FPS but the whole Track is a Slowdownparty
Casino Palace - Good
Lightning - Good at the Start but after that much Slowdowns
Big Blue - Same as Lightning here =/
