The Idolmaster One For All [BLJS10260]

Your CPU is an engineering sample, which model is it?
Needs verification without SPU Loop Detection and SPU Preferred Threads to 1/2.

If it still happens, add a game report so it can be moved back to Ingame.

I suspect it is an i7-8700 engineering sample, seems to match the spec reported here

8700k

My mistake was following above poster's advice on settings. Running the game with default settings gave me much better results, after that i only had to upscale it and force white buffer.
