@hrydgard This is probably the same as this issue https://github.com/hrydgard/ppsspp/issues/10229, right?

@marosis Turning off "Simulate block transfer" fixes the performance issue.

Weird. I don't have this problem on my phone using Vulkan. Instead I get a weird "mirroring" effect when I enable "Hardware Tessellation". The game is not playable on Vulkan...

Right. It doesn't!

Yes it happens on both backends. I don't have the PC version installed. I'll install it and report later.

Update: The issue also happens on the PC version, regardless of backend: 

Oh. Well in that case, here it is: [UCUS98641_0001.zip](https://github.com/hrydgard/ppsspp/files/1527529/UCUS98641_0001.zip)

@hrydgard Burnout Dominator is also affected by "Simulate Block Trans." (disabling it makes the game 2 times faster)

@hrydgard @unknownbrackets I realized that if you turn on Software Skinning the game constantly slows down and its speed never recovers no matter what. But you have to do certain...

@unknownbrackets There are some errors:  The console was constantly spamming the first group of messages when I was using Auto CPU clock speed, after setting it to 333 MHz...
