This bug occur in all video backends. With OpenGL the frame drop is less aggressive (5-10 FPS), but the same problem are here too

Definitely not 4.0 imho, we won't have the time to fix this. Not even sure how fixable it is. Does it lag that much if you disable PE logs?

Disabling the logs doesn't change anything, still cause the sudden drop from constant 60 FPS to around 1-5 FPS... How I remove the 4.0 flag from the issue title then?

Try checking "Skip EFB access from CPU" in the hacks tab of the graphics dialog.

Skip EFB access from CPU works. I'll add that to the wiki page...

Praise the all mighty EFB access cache \o/

Game is hitting a code path which is known to be slow.
Updated by JMC4789 over 11 years ago
Even though this is a performance issue, knocking a Core i5 3570K to 0 fps is pretty impressive. And the fact it works fine in OpenGL leads me to believe it may be a fixable issue.
Wouldn't this be better labeled as wontfix?

It is a fixable issue, and it will be fixed with a VideoCommon refactoring. I'll file an issue about this.
